I can't see the wood for the trees any longer.
Switching road frames and groupsets - Shimano for Campag, both shells Italian threaded, both double cranks. Was running an 118mm UN54 pulling 6 speeds - from what I can tell Campag come no wider than 115mm, which are for triples.
I'll have a double crank pulling 8 speed - is there an obvious penalty I can't think of from using a double crank on a triple BB? In any event 115mm sounds too narrow, unless I'm missing an appropriate, wider Campag spindle? I know I could use another brand but would prefer Campag for consistency. Will their 115mm be fine for a double?
