Some tiny much needed parts I could not get in New Zealand. Ordered and they arrived within a week. A lifesaver and really happy.

God bless the traders (like SJS) that have those kind of attention for "minor issues" of their buyers and treat them like major problems, but for a little price!

The adapters were easy to fit for me but as yet I have not been able to judge the benefits.

I had been running my schrader rims with a loose valve stem until eventually the stem tore out of the tire. I am sure as a consequence of this practice. Hopefully this will never happen again

My Ridgeback Voyage is really good but yuk schrader valves! This is exactly what I needed, although you can get a better looking metal one for a little more money.

Does what it says on the tin! (But it is expensive for such a tiny piece of plastic.

Works perfectly on traditional Mavic style box section rims. Too deep to use on the sort of rims that have a separate bore under each shoulder and only a single thickness round the spoke holes. It can, however be cut down, but it then loses the bayonet that holds it in place. You then have to rely on the valve collar to do that. But,for box section rims, it simply does the job!

Holds valve stem securely, to convert schrader drilled rims.
