bottom bracket for singlespeed

[plain lazy]

I am building up a singlespeed but have not got the bottom bracket. As singlespeeding puts greater forces through the crank, should i opt for a beefier BB, something designed for freeriding over a light weight XC or wont it matter. This is my first singlespeed attempt so i'm green on the subject. oH and while i'm here, does anyone wanna sell me a 1. 1/4 quill stem.

cheers

Personally I use a steel BB axle for SS. It doesn't have to be a freeride/DH BB though (mine's a Middleburn cromo).

The cost and weight saving for the Ti ones aren't really worth it. That plus Ti is more fragile than steel anyway (most Ti BB manufacturers will state a max rider weight limit). Besides as you're dumping all the gears an extra 150g in the BB won't make much difference anyway.

Any part of a SS drivetrain should be as strong as you can get it, don't go lightweight whatever you do. Steel is your friend

I've had Ti and it was fine...but steel is good enough.
What you havn't mentioned is the type of BB you are using.
Surely square taper

Does singlespeeding put the drivetrain under more stress?

Whats the difference between a fit rider pushing a 32/16 gear up a hill on a geared bike and a singlespeeder pushing a 32/16 up a hill?

Be interested to know if there is any data on this.

^^what he said^^

I suspect it **feels** like it's harder work, but actually it isn't.
I'd say steel over Ti for a bottom bracket anyway, though.

Bog standard shimano sealed b/b, in the appropriate length . B/Bs fitted to my stock single speeders have been lowish quailty oem generic efforts - never had a problem.

This is something I have wondered for a while. :?: :idea:

I suppose if anything, you might occasionally use more torque to get up the hill in that single gear where you'd wimp out n change down. All I can come up with.
