Sun XCD Groupo
The New Sun XCD Group is special for a number of reasons, it’s new and still fairly easily available, the hubs are very light, and the rear derailleur can handle up to an 11-34 tooth cassette.
The rear hub is very light with it’s red alloy cassette body. It has lovely classic high flange hubs, and super smooth sealed cartridge bearings for fast rolling. The sealed bearing are thoughtfully the two most common sizes and readily available.
The alloy cassette body means that it should really only be used with higher end cassettes that have light weight alloy spiders.
It has the traditional spacing used from 8 speed through 10 speed. So any 8-10 speed cassette will fit (*excluding Campagnolo). 7 speed cassettes will fit with the addition of a 4 mm spacer.
The body is alloy and the cage is chrome plated steel. They work well with compact doubles.
They are all braze on and will need the braze on adapter clamp, which we offer.
The rear derailleurs only comes with a very long cage. They work well to wrap a lot of chain and can do up to an 11-34 tooth cassette.
Matching the group:
We like matching Sun XCD group with a Shutter precision dynamo front hub, Sun Xcd crank set with T.A. chain rings mounted with Velo Orange 50.4 hardware. Shimano dura ace 9 or 10 speed down tube shifters KMC Ultra light chain and Sram or Shimano XT alloy spidered cassettes.
