Genuine InnovationsDisc Wheel Pump Adapter, Angled

While designed to insert into a pump hose permanenly (with a hose clamp), there were no issues just inserting it into my pump's standard universal chuck ( which fits both presta and schraeder type valves).Would be nicer if it had a lanyard loop or other means to put a leash on it to keep it from "wandering off".I made my own just now. Not too hard.Appreciated the spare washers, too.Good deal.

Fits nicely into opening for disk wheel so it can be inflated. But it separates under air pressure, so you have to hold it altogether by hand while pumping--which is tricky unless you have another pair of helping hands. Would have been nice if it could have been threaded to attach to the pump.

Have disc wheels on my trike and have tried just about every angled adapter on the market and this is the very best and most reliable one I have used. It stays on every time and has never leaked.

It's not meant to fit into a presta pump, so you'll need to file it down a fair bit. And it won't stay on the valve stem like others will, so you'll need to hold it on while you pump, or get some assistance.

works fine, no problem.

It works, but I can't get it to stay on the valve while I'm pumping, so this requires two people: one to hold it on the valve and one to pump:(

Perfect. Buy it.

High quality product, and the ridged fitting makes a good seal with the track pump. However, it doesn't work with the Topeak valve extenders with the spindle that allows you to open and close the valve below () - the spindle is too long and so the adapter does not seal around the extender. That's probably more an issue with the extender than this product, but I'm either going to have to get new extenders or not use this adapter!

Does the job
