• Special order a Claris crankset with 46/34 instead, cheap as chip, and 34/29 is plentiful to start.

    Claris is a bit pointless, since Tiagra is so cheap and uses a modern BB. 2400 is strictly for OEMs to whom £50 on a whole groupset really matters, for the rest of us saving <£10 on a crankset which uses an outdated Octalink BB is silly.
