Should I sell the used Dura-Ace 7710 crankset w/bb (got it for $200), profit, and get something cheaper (i.e. omniums) or just run them on my new Soma rush build?
Should I build up my Soma rush and then sell the Mark V or have it do duty as a singlespeeder?
Should I use the IRO wheelset on the Soma rush or get the Wabi wheelset (or something else)?
Should I get 28c or 25c Panaracer T-servs? I weight about 160lbs.
1) How much are you selling it for? Omniums recently had a price increase so you probably won't save that much money. I'd be inclined to keep the dura ace, but that would depend on my budget
2) Would depend on my finances. I like the idea of having two bikes though, especially since the money made on a Mark V isn't all that much.
3) I'd get a new one. Again though, would come down to my funds.
4) 25s will be fine, but I love my 28s.
The BB with those Sugino 75s is a 113 or a 115mm? I don't understand why someone would have bought either of these when the suggested Shimano BB is either a 107 or a 110. Buying a new BB for these cranks is a deal killer.
But I could probably buy them and make some money...
According to Sheldon Brown, an ISO crank on a JIS taper will sit ~4.5mm further out than if you were to use a ISO taper of the same length. So if I used a 113mm JIS tapered Shimano BB, the crank will sit a total of 6.5mm out?
4.5 + ([113-109]/2) = 6.5mm
Or are you not supposed to divide that second quantity by 2?
i have the protype BB on both my S75s, works great, way less $
You're depriving yourself of the full sugino 75 experience... trust me I had the protype for a week before I gave it away to a cycling buddy for a legitimate 75 BB; smooth like butt'ha. I mean why compromise when you obviously didn't on the cranks? What floats your boat nonetheless.
