Abe, Earlier this year, I had this very same question, albeit for 650b Cliffhangers instead of your 700c ones. I was wanting to find out what Velocity’s opinion was on running narrower tires outside of the “optimum range”- specifically, from 43mm down to 38mm. I contacted them and here’s their response:
“Hello Mark, You might be ok with a 43mm, taking it down to 38 is probably too risky. The skinnier you go, the greater the chance of a tire blow off. Running with tubes is more secure than without, but I can’t really say what the limits are. Some tires fit tighter than others so there is no hard and fast rule.” FWIW, I ended up getting a different, narrower wheelset in which 38-44mm was in the “optimum range”. ~Mark Raleigh, NC > On Sep 27, 2019, at 11:54, Pancake <[email protected]> wrote: > > Summary: plan to switch to tubeless setup, but how small a tire is safe / > wise on a 700c Velocity Cliffhanger rim?
