Need correct inner tube for front wheel
on: March 25, 2020, 05:58:13 PM
Using the Motion Pro bead breakers ended up causing scratches along my wheel bead that I may not be able to repair. So, I'd like to consider permanently using an inner tube. Search resulted in temporary sizes when in a bind. I need something that can be on the bike regularly.

What size inner tube precisely fits the front wheel?
The OEM valve stem is a TR412. What size valve stem should be on the inner tube?

You could try with epoxy for scatch fixing. Clean, apply and then use fine sandpaper to smooth the surface.

Thanks for the recommendation. What do you recommend, JB Weld?

I used a dremel with a sanding attachment and then 800 grit sand paper in the areas where it was leaking, and it seems to have worked. So far the pressure has been holding steady.

I think I'll get a couple of tubes for my long road trips in case I have to change a tire along the way.

It should work perfectly - it's less fluid that clear epoxy and less fragile. Dremel is great for sharp edge removal, once removed sharp edges just fill the scratch with epoxy. One trick - apply the epoxy on wheel at room temperature. I mean - don't do it in a cold garage and cold wheel, epoxy could became too viscous and wouldn't fill well the scratch.

Wow - there is specific products for virtually all problems. Seems to be far better than epoxy.

P.D. If you can't find a product to fix your problem your problem doesn't exists yet  :001:
