I only have three !!

I have black 105 on the cyclocross - grey 6800 ultegra on the TT - it was built for the cycle show in Birmingham and was built with a long cage.

Ordered a new ultegra short cage from wiggle. And re the cabling - getting fettled by the Dr in a couple of weeks. None of this jagwire shite.

If you are doing a long hilly tri (IM wales for example) then you may want more of a 'road' type gearing to avoid having to mash the hills, but at 31.8gear inches, 34/28 should be spinny enough for almost any climb you are going to encounter.


ewan is right. you want a bigger gear than 39/23 for IM wales. :oops:

A snaller one you mean.

Bigger rear sprocket. Smaller gear.
