    Single 9 or 9x1 drivetrain?

    I am riding an Orbea Carpe H.30. It came stock with a pretty cheap generic single chainring crank with a square taper BB. After 3,200 miles the BB is shot.

    I am looking for suggestions for a modestly priced...hopefully a little lighter single ring crankset/BB combo. Ideas?

    My wife's road bike came with a octalink BB and low end OE Shimano cranks (not a series like Tiagra, 105, etc). I swapped them with a Tiagra crankset/Hollowtech II BB I found online for around 100 bucks and dropped 500g from the bike. Of course that's a double, but you can just run the outer ring.

    Im running a 1x9 set up with Deore Octalink cranks. With a 38T single speed chain ring mounted on the inside of the spider I don't have any issues. Im running a 12-28 cassette with a 9spd 105 derailleur and a LX shifter. Works perfect!

    you will probably find useful information on the Singlespeed forum.

    is there anything wrong with the crankset itself? why not just replace the BB? that's a lot of miles for any sort of bearing.
