I've got a 03 Trek Fuel 100, and a FSA Octalink Carbon pro TEAM ISSUE 48/39 Crank set.
This kind of presents a fit issue, as the BB that came with it was 116mm wide, and the left crank would hit the lower rear stay. However, if I adjusted the offset to the left, then the inner 39T chainring would rub against the right lower stay.

Does anyone know an Octalink V1 that is wider than the 118.5 available????
If so, what model?

Do you think the FSA Triple 53/39/30 would fit better?

There are some longer Octalink V1 BB's but they were proprietary to Santana (tandems). I think they made a 73 x 129 but its not listed in any Shimano Books. But I think you can get it from Santana for $80

You do know you are using a road crank on a mountainbike.

Its not a road crank on a mountain bike. Its a mountain bike on the road. I can't stand the road bike position, but I do so much riding on the road, and this bike is much more comfortable. 22kph is all I need. I need to be nimble in traffice, so a mountain bike is best fitted for me.

However, bring up a great point. The Octalink V1 isn't a mountain worthy BB.

Thanks for the lead on the Santana - I hope I'm not on a goose chase for a mystical item.

road doubles don't have the same clearance as mtb triples.

XTR BB isn't mountainworthy? wrong friend-o!

What he means by road crank on a mountain bike problem is this. The road crank has a larger diameter than a mountain crank. The chain stays on a mountain frame srpead out wider close to the seat tube than a road frame. The crankset and the frame usually occupy the same piece of real estate and thus rub. The only answer to this is to install an unusually long bottom braket. This results in several other problems one of which is pedals spaced very widely apart which may turn out to be uncomfortable. Another problem may be in obtaining a chain line that your shifting hardware can deal with. (you may not be able to get a front derailleur that will reach out far enough) Generally, this is not an installation that you should attempt unless you have a good idea of what problems are coming.
