About This Item
These are pretty standard inner tubes. As long as you pick the right size, they are going to work. I installed these on my Surron which has an aftermarket 21 inch front wheel from Milk racing. The tubes fit on the wheel well and work with my Shinko 241 tires. They hold air and I usually like to run them around 20psi. Haven't had any issues with flats yet but I normally go through 1 - 2 tubes per year. They are consumables so don't expect them to last forever. Thats why they come in a two pack. Overall, these are good tubes and work well with my Surron. They won't fit a stock surron wheel but if you have larger 21 inch wheels these will fit nicely.
Got my bike back on the trail just in time
Great product for great price
Not too thick, not too thin, the fittings work smoothly. Nothing to complain about!
Good set of inner tubes for my dirt bike, exactly as described, and performs as expected.
I replaced my front tire tube with one of these. The tubes are thicker than whatever was on there and they both held air for a ride and overnight after. I don't see having any issues with these tubes.
These replacement tubes work perfectly!!I have been running them for over a month of constant riding and they are running strong!Good quality, fit perfectly, light weight, and easy to install (like any other tire to install)The price is good for the quality you get. I will be buying these from now on!
Sized Correctly.Got these as a backup standby for my Son's bike.This way, if he gets a flat, can change it out and keep going.Shipped and arrived quickly.
Great fit for my 2008 yamaha
Nice medium duty tubes. No leaks and it seem like a decent value for your money. They function well for the intended size. They look like they are a decent quality so far for medium duty tubes.
