Regarding the BB - thanks @arvi for the input. I think I’ll grab an Omni Racer Ti maybe in 107.5, as you said to get the big ring better positioned across the easier cassette gears which is definitely my pref. The Ti model isn’t that pricey compared to a lot of boutique BBs costing more. And the Ti is 100g (almost a quarter pound) lighter than the BB that Riv includes with their frames (I just weighed a 68x110 and it’s 265g from Riv).
Regarding the front der - my normal setup steps are like those mentioned by Park Tools. The RH crank arm is close enough to the large chainring that there’s very little margin for angular adjustments (but I’ve tried). I’ll just go with narrower BB and an Ultegra chain and see what diff they make. Easiest done in coming weeks when the new Roadini arrives for buildup! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
