I do friction shift Ginz !! .... Always have ... always will :) I've stuck with FW's all these years because I have a stock of NOS and barely used Sachs FW's. . . . and the cogs just last and last and last ! I switched to Squirt chain lube last year.... and I seem to get even less wear on them. I never did quite get why they spec'd a 47.5mm chainline with 9sp., as the extra cogs are placed toward the center of the hub. This always perplexed me why they were engineered this way, as there is room to move the cogs slightly to the right, toward the dropout. The way they are, the angles are actually worse for the larger cogs in the middle and large ring, better if you ride in the small ring. Pros and cons, as always. But hey... cassettes are cheap, and meant to be replaced often... so if there is extra wear from the higher chain angles .... just go with it. Maybe they've designed more flexible chains these days that minimize the wear though .... just a thought.
I bet you can't wait to get your Hunqa built up ! Leslie, the Riv sizing ... I'm not sure why they post it, sometimes they simply don't change or update text though. Yes, the early Bomba frames could use a 107 or 110, as the driveside length is the same on Shimano and Tange(IRD) cartridges . When I bought an XD crank last year Riv told me the new Bomba's needed a 113 or 115mm, FWIW. The Sam is/was spec'd with a 107mm. Chainrings are not all exactly the same diameters either... some brands have a little higher profile teeth. I don't think they can accurately publish the data because they appear to make running changes in frames from batch to batch sometimes. Okay for them on a complete bike sale , as they can try and length they wish... but not so great for consumers who buy the frame alone and do not have a bunch of lengths on hand. It's always worth it to call Riv and ask, but never take it as absolute, they are human too .... there is no experience like first hand !! -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
