Anybody running a triple?(8 posts)

Anybody running a triple?rockbender

Just got my first CX bike (hooray for me!) and am running an Ultegra double right now. Ideally, I would like to go to a 110mm crank and run a 36-48 double. But, I was just thinking that my roadie has a triple on it, so why not do a swap? It would just be a BB and crank swap, maybe der's too, right? (yes - assuming the BB widths will swap straight across).

I've got an old MTB crankset, but the 7spd rings are thicker than 9, right?

BTW, I won't be racing, just leisure trail and fireroad riding / commuting. Also, running a 12-27 cassette.

thanks for the info!

I don't race either - cross bike is my all rounder and my only off road bike. So when I ride single track, I ride it on that. I definitely need a triple on steep singletrack. Sounds like you should be able to swap the gear from your roadie as long as they're compatible groups (ie, both 9-spd Shimano or 10-spd Campy or whatever else).

I think I will try making the switch - seems like a logical choice!

Got campy 9 with 30/40/50 - works great.
No shortage of gearing here!Steve_O

XT crank up front (44-32-22T) and 9 speed XT cassette in the rear (11-32T). Not much I can't crank up (I'M the limitation not the bike). Never run out of gears on the road (no downhills in IL).

The only issue I can think of is that your chainline might be slightly out of wack if you put the triple on the existing BB. Try it out and see. If you have problems in different gear combinations (ie - big/big) then maybe a slightly shorty BB (or more chain lube :-)
