Jan's point is well taken, but the Gen2 Kogswell actually take Hetres and VO Zepplin (52mm) OK. I recently did some bike camping on the San Juan Islands and rode on some mixed terrain, and the Kogswell with the mentioned set-up work perfectly.
I have both 42mm Hetres (40.5mm on synergy rims) and 38mm Soma B-line tires (37.5mm on synergy rims) and the difference in appearance and feel are noticeable. I would say that if you can fit, use the wider tires. Question for Jan and others: my Hetres have never stretched beyond 40.5mm, even though a pair is now at around 5000 miles. Are the Babyshoe Passes wider than the Hetres (do they measure to a true 42mm on Synergys? Do they stretch beyond 42mm on Synergys or A23s?) thanks, Franklyn On Friday, August 8, 2014 7:53:41 AM UTC-7, Jay B wrote: > > Plenty of 650b Rivs can take 42mm tires with fenders.
