this guy is using one on a Surly Krampus so it is being done http://www.whileoutriding.com/bike-talk/gear-ponderings
I think it depends on a lot of things, fitness, how much you pack, steepness of terrain etc. I really like having a bailout gear of around 20" for steep dirt road climbs. On paved roads with moderate loads it's more doable. I once rode hwy 1 from Eureka to SF with a low of 27" and was fine. ~mike -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
