Solid Tube

Comments On May 02, 2013:For the price, these things are AWESOME. Fairly thick tubes that look like will take a bit of abuse, for a cheaper price than most thin tubes. Had them on for a little while, and have done very well

Quality seems good.

Comments On Jan 19, 2013:I haven't installed them yet, but they are definitely thicker than the standard tubes, and should hold up to my commuting and moderate trail riding quite well.

Comments On Dec 27, 2012:This tube is very thick. it feels more like an extreme duty inner tube then anything. just covered it with baby powder and the inside of the tire with baby powder then you will have no problems with installing
