Topeak Pressure Rite Presta Valve Adapter, Silver

This little invention is a saviour and at a price that is reasonable. Having recently purchased a rear disc wheel, I quickly realised that there isn't much space to pump the tyre up, especially if your using a normal bike pump. This was a concern for me as I like to be prepared during races, knowing that I have the means to fix a puncture should the worst happen. Adding this device into the pump housing, there is loads of room to insert into the valve without bending the stem. 100% piece of kit that needs adding to all tri racers with disc wheels.

Great service

Screw on mechanism simply doesn't work ..... in 9/10 cased either a) crewing on is likely to unscrew a tubeless valve at the rim, or b) unscrewing takes the valve core with it. Do not take out on the road .... you'll be left at the side of the road with no co2 canisters . i wish I could rate this zero.

Brilliant

Brought this adapter for my tt disc wheel worked perfectly.

Brill item , also got it fast

Difficult to attach. Still need two people to inflate disk wheel

Not impressed. Bought it for use with a disc wheel and couldn't get it to be fair tight or connect properly to the pump. Returned and bought alternative which works much better.
