Jeff Lyon Collaboration Rando Small Batch Frame Sets



The first batch of Norther Lyons are heading back from the powder coater tomorrow (Friday Oct 11th). This is the 54cm batch. Sorry they’re all spoken for. Pre order to get into the next batch! With any luck we’ll get them all faced and chased and frame saved this weekend. I’ll try and take lots of pics!

Jeff's deep into the second batch of Norther Lyon frames, and they’ll be in house for braze ons and powder coating! (Size 52, and yes they’re all spoken for). Here’s a pic Jeff sent me of the 52cm frames looking pretty close to done, and a few his daughter took of him adding the front fender mount to the underside of the steer tubes before brazing up the forks! Nice shirt!

56cm are up next and there is one spot left, so if 56cm is your size email me to get you into this batch!

We're also working with the wonderful artist and bike mechanic Spencer Hawkes of Nomad Patches on the art. Check out these final drawings of the head badge, seat tube badge and the down tube decal. Note the NL and then the blank space on the bottom of the seat tube badge. We’re going to hand stamp the number of the frame into the badge and then place them on the bike like the 531 or other tubing badges of the past. Don’t worry Jeff is still hand stamping serial numbers into the bb shells.


Bicycle head badge specialist Schild Nederland is working on the head and seat tube badges for us using Spencer’s art. They probably won't be ready in time for the first batch or two, but we'll ship them out to everyone after the fact.

Check out this rendering.


Check out these pictures of the first prototype! (It's Sold!)


Check out these pictures of the prototype with a one inch threadless headset and IRD bright silver stem installed.

Above are some pictures of the headset set up on the Norther Lyon collaboration prototype. I used the NOS Miche 1in threadless headset, (*custom polished).

This set up also has a clamp on front brake cable stop, one inch headset spacers, and a one inch shim to shim the common 1 1/8 stem to the one inch steer tube, and a Velo Orange Decaleur (use the one inch one). I've stocked up on these bright silver IRD stems in many lengths, angles and bar clamp diameters; hit us up for availability.

I'm working on a blog post about setting up the threadless headset for this bike, but it will be a while before i can get enough pictures.

*Pics of the headsets by themselves are to demonstrait the difference between the stock finish on a one inch threaded Miche headset and the finish of the custom polished one inch threadless Miche headset.


Details: the Norther lyon!

Order yours! Pre-orders and down payments.

The Norther Lyon will be a silly inexpensive ode to Jan Heine and his thoughts and reviews in Bicycle Quarterly and Jeff's 44 years of frame building experience, and a little of our touch mixed in too. They are all going to be made with a custom mixture of extra light 7.4.7 high quality tubes from True Temper, Kaisei, and Reynolds 853. So light and nice that we're recommending a maximum rider weight of right around 180lbs-ish (this is only a recommendation not a law, or exact science, we're not cops, do what you think is right for you). They will all have the Kaisei super supple "Toei Special" fork blades and the light and elegant Grand Bois fork crown from Compass Bicycles.

They're made to fit 650b wheels and 42mm tires perfectly and correctly. (You can safely squeeze 48mm tires without fenders, and with fenders with a little massaging/dimpling of the fenders. Jeff has reworked the chain stays for a little more tire clearance!)

The frames are made with small raw no file fillets by the amazing Jeff Lyon. Forks are fully silver brazed. (Jeff is not currently taking custom orders, and only want's to build the Norther Lyon frames. We however are taking custom orders if you're looking for something similar but lugged/a bit more refined.)


Braze ons Options and Features:

The Norther Lyon will come standard with 1in threadless forks (You can talk us into a one inch threaded steer tube for quill stems upgrade for $50).

Standard braze ons will include a single rear fender eye on each rear drop out for fenders. Double eyes on the front drop outs, as well as mid fork barrels for fender and lowrider front racks. The fork will also come with a custom under the Crown boss for front fender mounting without having to use a Daruma or L bracket (very trick!). Same for the the chain and seat stay bridge!

The frame will have two sets of water bottle cage bosses: one on the down tube and one on the seat tube, (Sweet talkers can get us to add a set for a third bottle on the under side of the down tube for $50); traditional down tube Shift bosses (these will work with any down tube shifters or bolt on cable stops for bar ends or brifters); three split cable stops: two on the top tube for the rear brake and one on the chain stay for the rear derailleur. The bottom bracket shell will be drilled and tapped for a replaceable cable guide (included).

There is also a pair of pump pegs on the non drive seat stay for a modified Lezyne Road Drive size large frame pump. (Available for an extra $59).

All Norther Lyon frames are dynamo ready with two reinforced holes in the fork, and one in the down tube, and a driller hole in the bottom bracket shell for internally running the dynamo wiring, (for rear fender mount dynamo lights). This way all your dynamo wires can easily be run internally! Size 54 and larger frames can be upgraded to the Compass tail light braze on for $50 + $169 for the light itself. (We have and will make more blog posts on how to run dynamo wiring, and are also more than happy to provide this service to your frame before handing it over to you for $40 per dynamo light/USB Sine Wave Charger).

With your Norther Lyon you get your choice of braze ons for either Rene Herse, or our Norther modified, or any other standard canti bosss (standard); or Compass Bicycles hard mount center pulls ( $200 upgrade: These mounts also work for vintage M.A.F.A.C "Raid" brakes. Or even, as Jeff suggested, a combination of the two (He thinks a Compass brake up front and a set of cantis on the rear would be pretty neat)! Frames with hard mount studs will come with Compass braze ons for the Compass CP1 front rack. For the Canti boss version we recommend the Velo Orange Randonneur front rack for cantilevers. (We have these brakes and racks available and would prefer if you order it from us with your bike). We can also make a custom rack or rack set for you, see our custom rack page.

Current Batch:

Jeff is currently finishing up the 52 cm batch. The next batch will be size 56 cm and Jeff will probably start it next month.With each additional batch being ready to ship every 4-6-ish weeks after that (with any luck). It looks like the fourth batch will be 58 cm, then probably 60 cm. There is still room in the 58 and 60 cm batches.

There is still at least one spot left in all of these future batches! … for now.



Currently offering sizes 52CM, 54CM, 56CM, and 58CM.

More sizes and detail to come. 60cm and sub 52cm frames will get made, but probably not until next year. Put your deposit down to lock in your prices and fill the batch (full batches get made first!)




All frames, (with the exception of the 60cm and larger) will be made with standard sized, (one inch top tubes, 1 1/8 seat and down tubes), tubes, in very light weight .7/.4/.7 wall thickness and take a 27.2 seat post. All frames  come with a one inch threadless steer tube, (unless specifically ordered with a threaded steer tube for quill stems). All frames will come with a seat post binder bolt and under the bb cable guide. All frames will come painted, decaled, prepped and ready to build!

A very light 5.89 pounds frame and fork for size 56cm prototype.



As of now, we are powder coating each frame individually locally at CC Coatings using Prismatic Powders. We are offering your choice of:

Bronze Metallic Brown. Prismatic color Lazer Copper PMB-4151. Lazer Copper is a dark brown base with a heavy copper metallic. This color is a polyester metallic powder coat and has a high gloss finish.

Fine Dark Teal Metallic. Prismatic color Misty Aquarius PMB-4245. Misty Aquarius is an aqua blue and dark teal combination with a heavy metallic. This color is a polyester metallic powder coat and has a glossy finish.

Frenchy Robin's Egg Blue. Prismatic color Troll Blue PSS-2657. Troll Blue is a light sky blue. This color is a polyester solid tone powder coat and has a high gloss finish.

Gloss Black. Prismatic color Ink Black PSS-0106. #1 Gloss Black In The Industry. Prismatic Powders developed Ink Black to be the only high gloss black powder coating you will ever need. Ink Black has an incredibly deep, mirror like finish with amazing flow out, yielding the highest gloss, true black finish available in a powder coating.

Maybe a mystery color when we feel like it on certain batches.

Sorry no light colors. They're a pain and usually don't make the logos pop!

In the future we might let the first pre sold bike customer pick the batch color. We'd save money and time and really prefer to do each batch all the same color.

*This is another good reason to put your deposit in now, not only will you lock in your price, but you can pick your color.



Check out these pictures that make me super happy.

This is an often overlooked detail, and it's perfect on these Norther Lyon frames. The seat binder area has lots of room for any rear cable hanger you like! We like the Surly Bikes one because it's all stainless and has a barrel adjuster. They look even better polished! Nitto ones fit great Too, and the Rene Herse one will fit if you modify the binder bolt itself by cutting down the female side several mm.

We have all of these and a few other in stock!

*Note: Jeff is planning on changing this seat binder to one that takes a threaded M-6 bolt instead of this traditional seatpost binder bolt. It looks like it sticks out just as far and should handle all these binders just as easily.


Questions and Answers:

I'm anticipating a few questions so lets answer them here.


Hey, I want to do an bunch of stuff this bike isn't designed for, will you please tell me it's designed to do what I want!?!

No. It's designed to do one thing very well. If you want to do other stuff it probably won't work as well as a bike designed to do that other stuff, but again we're not cops and aren't telling you what to do, so do what you think is right for you. We just want to let you know that it's not a touring bike, gravel bike, hover craft, or space ship. It's not made for vintage hubs, or odd sized seat posts, or big cruiser bars. It is what it is, and it's awesome! Why want it to be something else???

Hey, isn't one inch threadless obsolete?

We'll yes, sort of, but not really. It was replaced quickly with oversized 1 1/8 threadless, so there were not a lot of headsets and stems made back in the day. Many frame builders and an occasional new bike still use this size and Jeff said that 90% of the custom bikes he's made are one inch threadless.

Several companies still make headsets including IRD, Cane Creek and Chris King. I've also acquired a large stash of NOS needle bearing Miche headsets in anticipation of these bikes being popular. Available in our store for only $65. I always strongly recommend needle bearing headsets on low trail and dynamo tail light equipped bikes; and don't recommend sealed cartage bearings on low trail and dynamo taillight equipped bikes as they can cause some issues like poor grounding of the taillight and fork shimmy.

Shims from one inch to 1 1/8 stems are cheap and available so you can use any modern 1 1/8 stem. We have a nice selection of IRD bright silver 1 1/8 thread-less stem, Velo-Orange and Compass Cycles also have very attractive ones (and we'd be more than happy to sell you any of them and install them if you like). The Compass stem even has a great decaleur solution and drop spacers kits! (We're also about to release a custom decaleur for standard four bolt threadless stems!) There are a few nos and used one inch threadless stems out there if you want to search. Many frame builders will make you a custom one too. We may also make some matching no file fillet batches of stems for these bikes if there is enough interest. We'll keep you posted if we go that way.

Hey, are there, or why aren't there, rear rack mounts?

No rear rack braze ons! Yes we know they're common on lots of bikes and people think they like rear racks because they're common. No that doesn't make them good, Low trail bikes don't like to have weight on the rear, and these aren't touring bikes. They're really light weight performance low trail bikes and they wont ride optimally with rear racks. There are lowrider mounts on the fork for larger light loads that wont fit in your handlebar bag. And these bikes are made to carry weight up front and be ridden exclusively with handle bar bags (which is the best way to carry weight on a bike anyhow).

Are you going to do 700c bikes as well as 650b?

Jeff would like too, so I'm guessing the answer is yes, although I'm not sure why anyone would want one when 650b ones are available? 650b!!! I don't know when this might happen and don't have any more info on it as of now. I'll update the website and post it all over Instagram when we do!

Are you going to do a disk brake version?

No. Disk brakes make a huge amount of torque and break light forks! You have to have a super heavy duty stiff fork and that defeats the whole point of ultra light super supple bikes!

Will you customize it--change the braze ons, change the frame sizes, do mine with lugs, change the trail, make it for internal hub or belt drive?

Nope! The only way to make them this cheap is to batch them out and make them all the same. If you want custom stuff, you need to order a custom bike. These are as is just like every other batch bike, or off the shelf bike (sort of). Mark and Jeff think it's a mistake to offer any options at all, and if it becomes a huge hassle i'm going to get rid of all the options we do have! If people waste too much of my time i'm going to remove the options and they'll all be threadless and cantilever only, or only offer the Compass brakes on certain batches. This being said, someone asked if he could get his without the mid for braze ons for lowrider racks, and if he could get it without a powder coat job, (as he has a local painter he likes to work with). Turns out the answer was yes! Much easier to omit a few details even though it's a bit of work to keep double checking and to make sure we leave off a braze on that all the other bikes are getting. It can feel wrong as we're constantly double checking to make sure we aren't forgetting anything.


Here's a cut and paste of several good questions i recently answered for someone interested in ordering a Norther Lyon. Think you might find them interesting too.


What fender do you recommend width etc?

I'm a fan of the Velo Orange Zepplin fenders for their hight and width and ease of installing, but anything that says it will fit. 650bx42 tire will probably be fine.

I am not familiar with the fender mounting you describe (no daruma no L bracket) – in your experience has this worked well?

Yes this works way better! All you have to do is drill a hole in the fenders and use a bolt from the inside/underside of the fender, through the fender and into the threaded boss in the frame! Almost as easy as putting a water bottle cages on!

How much clearance is there between the tire and the inside of the fender?

22mm perfect for a clean 20mm of fender clearance and a leather washer!

The compass mount(and light) mounts on the seat tube – does the wire go via the bottom bracket and up the seat tube?


How much clearance is there if a SKF bottom bracket is used? Is there space for the electrical cable to stay internal?

Yes, it's tight but plenty of room. The light needs to be installed first. And we have a hole photo essay blog post about this, and are more than happy to do it to your frame before shipping it to you.

Then you just need to make sure you don't snag the wire and damage it between the threads of the bb shell and the threads of the bb while inserting the bb, (we're also happy to do this for you).

What is bottom bracket threading and width?

Standard English threaded, with a standard 68mm shell.

What is clearance between crank arm and chain stay?(the 42 width tire plus the fender and chainstay might make this quite tight.)

This number depends entirely on what width bb and the brand of cranks. They're all different, but there's room for even the tightest fit such as t.a. cranks and the correct bb width for said cranks.

What is smallest distance from bottom bracket to front wheel and fender (toe overlap) I might work this out from the dimensions/angles you give but its always good to have an actual measurement to confirm.

Everyone is so concerned with this number and it's totally not important... Like at all. Especially on low trail bikes, with longer then normal fork rakes and smaller 650b wheels. You'd have to have a custom frame made with the shortest top tube ever and freakishly long feet to have this be a problem on a low trail bike.

I’m intending on using the compass rene herse crank reproductions in 171mm length.

You should have no problem with these cranks! The bike's basically designed with them in mind.

Does anybody have problems with ankle clearance with cantilevers?

No. The only time I've had clearance issues with cantilever brakes is if I'm test riding a sub 46cm compact children's mount bike.

I would like to try the miche needle bearing headset – polished of course.

More of a statement than a question, so no problems here!

 I have not had a front rack before, I have not used a rigidly mounted front bag either. How do I pick stem decaleur bag and rack so they all work together?

Now this is a tough one! Totally depends on the size of the bike, quill or Threadless stem, where the rack sits and how high you want your bars! Once we figure all this out we can measure the available space and decaileur options and pick a bag.

Other than that this question just has to many variables to give any real answer.

Front derailleur mount band or braze on? From pictures it appears to be band. Can you confirm this please?


Seat post diameter?

27.2 the most standard and common size for high end and modern bikes.

Rear hub spacing 130?

Yes 130 rear spacing for road cassette hubs.
