What is this?

Hi guys,

Can you tell me what that small thing is, that small nipple? It's rubber and can be found on the front and rear rim, and on both rims its position is on the opposite site of the valve.



Second question: I haven't been able to find a tire shop that sell 21" inner tube and 18" tube, they sell smaller tubes but not 21" tube or 18" tube. Where do you guys get yours from, any on line source you can recommend?

I want to have those tubes as spare tubes. I already bought Rema Tiptop patch kit from a Rema's local distributor here and want to complete my tire repair kit with spare tubes.

I will keep on looking, but if I can't find it locally I will have to buy it from overseas.

Thanks in advance.

Plug for rims that are bead-lock compatible, maybe?

Yep, rim lock hole.

Some people only carry a spare front tube and use in the rear in an emergency. Spare tubes take up a lot of space.

Thank you RDTCU and DYNOBOB.

What size tires are most common in Indonesia?

I think tire size that common here are the same as every where else. It's easy to find tires for 17" or 18" rims, that's the common rim size here ... tires for 19" rims also can be found but not as easy. Tubeless tires are available everywhere and easy to find.

However, looking for inner tube for the Husky was not easy because the majority of the bikes that use tube tire are small bikes, 100-150 cc bike or moped, with small diameter rims. AFAIK 21" rims are not common here.

But I found one ... Well I didn't find it, my friend did. I spread the words and one of my friends found a shop outside of Jakarta near where he lives that sells one and bought a 90/90-21" tube. He also bought a 100/90-18" tube which is a wrong size for the rear tire, but I think it can be used in emergency, am I correct?

Thanks very much guys.
