Reading with interest your adentures with the Modal project bike, and curious about what you’d think about an adaptation I’ve been wanting to try with a slider dropout bike (should I ever get one.) My most recent frame was built with 132.5 mm dropouts at the builder’s recommendation (Moots) to run 130 or 135mm hubs. In normal derailleur “mode” I run 130s (or Bullseyes with extra spacers to be 132.5 exactly), but I also run a 135mm Rohloff hub without having to force the dropouts apart. Nice. But would this work and be better: build a slider frame with 135mm spacing and run stronger 135mm wheels for touring and general riding. But when road racing or in any other situation where borrowing a spare or panic-bought wheel might happen replace the stock sliders (the sliding aluminum parts) with another pair that have dropouts spaced 130mm (and the derailleur hanger positioned to match). That is, offset sliders. Whaddaya think? Thanks, —Eric
Dear Eric Your Modal bike concept sounds interesting and in concept seems workable. However, there a few more things you should consider.
