If it Works for Fat Bikes...
by Adam of Prairie Village, KS on November 14, 2016
Ownership: a few weeks
Tech Knowledge: average
My bike runs 650B x 2.8 tires and came originally with WTB 2.8-3.0 tubes; these Q tubes are spec'd for 2.0-2.3 tires but are working perfectly. I know that going tubeless is the best way to reduce rotating weight, but in the meantime, the Q-tubes are about half the weight of the factory-option WTB tubes, which is a very noticeable difference.
None so far - the tubes hold air well over time and are much lighter than what they replaced.
Only tubes with 60mm long valve stem and removable valve core

Only tube with presta valve stem long enough (60mm) that fits deep or aero 20 inch rims, AND has a removable valve core so you can add sealer. If both of these conditions are true for you, this is your best and only choice.
Until I found these tubes, I had to buy expensive (and leaky) valve extenders for tubes with shorter valve stems. There are tubes withOUT removable cores that have 60mm long stems, but you cannot add sealer.
