No complaints! they are very durable and hold up well never had a flat!

if you can afford them buy them. riding with anything less is not my idea of being smart. think about it, flexing, rubbing, landing, stem movement, dirt, water, errosion, need i go on?

Only tubes i use and recommend. Nothing worse than being stuck with a flat on the trail. Little more difficult to install but 100% worth it.
