Review on SL Bicycle Tube Challenge by Mark Erandio

Don't waste your money. If you are switching to latex tubing, order a different brand. I vented one of them and it exploded at only about 100psi. Another dented when I put less than 15 pounds of pressure on it to install it. I've seen a response to a complaint about this which indicated that bulges etc are standard on latex tubes and that's only because they aren't meant to be inflated until after installation so the tire will contain the bladder and the can eliminate bulges. Don't fall for this nonsense! I did a comparison between one of these Challenge brand hoses and a Vittoria brand latex hose. Both hoses were inflated to about 12 psi. The Challenge tube contained a huge bulbous bulb. Also, the Vittoria tube appears thicker, while the Challenge tube is so wafer thin that you can see through it when there is air in it. To add insult to injury, when I contacted the seller to get a replacement they basically accused me of being too dumb to know how to fit a bike tube and tire. I will stick with Vittoria and use my LBS or another Revain vendor.
