Review on VeloTubes FR 21 40Mm Black by Matthew Aiono

Revainrating 5 out of 5

Works great - may only need drilling of the inner rim layer - NOT the outer rim layer

Works well in non-tubeless rims I converted it to tubeless using Gorilla Tape. If needed, simply drill 1 inner layer of the rim to widen the hole so that the tapered rubber covers the hole in the *middle* of the tapered rubber section, not just the small end to create a good seal.

Pros
  • Tires and tubes
Cons
  • Some minor things
