Long Haul Trucker Build - Chainset and Bottom Bracket, what are my options?
Hi
I've not built a bike before and its now time to pick out a BB and Chainset. I have two queries i hope you can help advise:
1) What BB for a Surly Long Haul Trucker? I'm looking at a Shimano UN54 but i'm not sure what length i need? Some people use 113mm and some 110mm.
2) I have a mountain bike chainset at 44/32/22 and a road bike at 30/39/52. I much prefer to ride the road bike and find this very comfortable. My rear cassette on my LHT is Shimano XT M770 9 Speed Cassette a 11-34T so what are my options? I don't really like 44/32/22 setup, so I was thinking of perhaps the Shimano XT M771 Triple 9 Speed Chainset 48/36/26 as a happy medium. I guess i can't use a road chainset on this cassette, or does it make no difference?
Thank you for your help.
