A Little Help...

Hi All,

New Focus Jam2 owner, and what a beaut she is....

Just a few questions, that hopefully some of you guys have faced and managed to sort.

So I am in the process of going tubeless, the rears gone on ok but the front is leaking from the valve, these offset rims mean the lock screw sits wonky....

Can anyone recommend a specific tubeless valve or a workaround for this?

Also has anyone fitted braided hoses to their Jam2? The rear looks like it could be a pig and any tips would be great.

Thanks

I had the same problem for exactly the same reason. Following a tip given on here (from @steve_sordy I think) I put a couple of windings of PTFE tape around the base of the valve before reinserting it. Leak plugged.

Previously, on my clockwork bike, I found it impossible to make the schraeder valves airtight in the narrow rims. A homemade gasket of Fermit solved that problem.

Thanks Graham,

I read quite a few tips on here and ultimately I used one full wrap of Gorilla tape over the existing (rim tape) and that seems to have done the trick.

I am now wondering if I should strip the rear and add the Gorilla tape to that one too.

I was just perplexed by the shape of the rim..... But, they were still up this morning so fingers crossed

I didn't even know tubeless was possible with schraeder. All I've ever seen is Presta.

Both Joe's and Stan's make 'em. Plus a host of others. I prefer Schraeder. It's a far more robust valve without that weak bit that gets bent when I'm shivering in the freezing rain and in a hurry. However, as the bike is still under guarantee, I'm not about to drill out the rims just yet.
