Hi so the right arm on the crank has threaded and now need a new one only problem is I can't find one anywhere. Can I replace this with another model straight swap or can anyone help me source one any help welcome

A Claris FC-2403, because it uses the same Octalink v2 121mm bb as the FC-R453, would be a straight swap.
@RecordAceFromNew thats tad heavy, my chainset from Spa, using their own Zircal rings ok tad more expensive @ £65 or so, plus 113mm square BB weighs in at 740, plus being a standard 74/110 compact triple you can fit various rings. Looks a bit smarter too I think.


Except the bolts, can't afford nice new shinny ones, they also do a cheaper chainset about £35 but this needs a 110mm BB, comes as standard I think 28/38/48 but is 74/110BCD but with one hidden chainring bolt, not sure on the weight.
