Prototype Decaleur

150.00

Small batch prototype decaleur for threadless four bolt face plate stems.

They are spring loaded and quick release. They have a laser cut polished stainless bag side that has three bolt holes to mount to your bag, and two slots that allows you to bolt the female quick release mechanism to just about any width for just about any threadless stem.

The male side of the quick release mechanism has M5 x .08 threads. These replace two of your stem’s face plate bolts and have 8mm wrench flats so you can tighten them down. They also have some spacers that come with them as most stem face plates have deep pockets that are too small.

It’s best to replace the stem’s face plate bolts with the decaleur’s male bolts first, tightening them in sequence and to torque specks just like any how you would install any stem face plate bolts.

Then loosen the female side and attach them to the male side.

Next center the bag side drilled out plate to the stem and tighten down the bolts that secure it to the female side of the quick release mechanisms.

Check to make sure that everything is in place and the quick release mechanism works well and you like how centered it is on the bike. Both quick release mechanism need to be operated at the same time. This take some amount of dexterity. If it pops on and off with no problems you are ready to mount the bag. If it’s to tight and difficult to get on and off easily then re adjust the female side bolts letting the quick release mechanism slide in the adjustment slots until it fits well.

I will make a blog post about the best way to install them at some point. I have made on on how to install bags and make stiffeners and recommend installing them correctly and using my bag stiffener design.

*These must be used only to locate the bag to the stem and must be used with a front rack. The rack must support the full weight of the bag.

*The decaleur is only designed as a quick release to hold in place an already supported bag. The bag needs to sit fully supported on the rack and line right up with the decaleur before being bolted to it.

*The stem should sit level on the bike. A 17 degree stem is usually best for this. The stem will need M5 x .08 threading for it’s stem bolts to work with this decaleur. This is the most standard size, but i have seen some stems with M6 bolts.

*These are prototypes and might not be the final design. They have no specific warranty but i’d love to know if you have any specific problems, and i will offer replacement parts cheap or free to anyone that has any problems.

*These quick release mechanism is chromed steel not stainless like i originally thought. On some the chrome is thinner than on others so while cleaning them up I polished through the chrome in some spots and you can see little bits of the brass showing through. I think this gives them a cool antique look so I’m selling them. If i can ever get these made in stainless i will.
