Submitted by kjhishere a Weekend Warrior from Redlands, CA, USA
Date Reviewed: May 6, 2009
Duration Product Used:1 Year
Price Paid: $7.00
Purchased At:Cyclery USA
Strengths:Puncture resistant. light weight.
Weaknesses:Always losing air. Stem is floating type. does not have a nut to hold it down on the rim.
Similar Products Used:Lots
Bike Setup:Fezzari Wiki Peak with lots of upgrades.
Bottom Line:I spend way more time filling these with air on the trail and in between rides than any other tube I've ever tried. I've run into a number of these where the stems leak constantly requiring air to be added during rides. Tighten the stem with needle nose pliers ... and then you need to bring the pliers with you to be able to add air if it starts to leak again.
I'm very glad I'm on my last one ... which I haven't even gotten one ride in on because the damn stem will not stop leaking.
Do not buy these. Waste of time.

Favorite Trail:Highlander
Duration Product Used:6 months
Price Paid: $7.00
Purchased At:Bicycles Outback
Strengths:Good against thorn punctures.
Weaknesses:Very pron to popping.
Similar Products Used:basic PV tubes
Bike Setup:'05 North Face Kichatana (Iron Horse Warrior Trail)
Bottom Line:I'm rather disappointed with these tubes. At 7 bucks a pop...I went though 3 of these in 3 weeks (all rear tire), then again I do jump off 4-5 foot drop offs. It even popped once when i hit a root. I wasn't really to worried about thorns since i put a liner in both tires, but the rear tire kept popping after jumps, and the slime was worth crap in sealing it. I could hear my tire hissing, and 2 minutes late, it was completely flat. It usually popped at the seals, so patching it was out of the question. I had my tires inflated to 30-35psi.

Submitted by mike a Weekend Warrior from edwards CA
Date Reviewed: May 21, 2005
Favorite Trail:on-base locals
Duration Product Used:3 months
Price Paid: $7.00
Purchased At:block shop
Strengths:Has resisted all thorn punctures which are very common in the Mojave desert.
Weaknesses:The rear tube began leaking air around the base of the presta valve within the first two days of riding on it. The Block shop repaced it for free (block shop rocks!) but within three months it did the same thing. So far the front tube has held up just fine other than the presta valve being difficult to unscrew (even after removing sealant buildup.) It's also a little heavy but I don't really care.
Similar Products Used:slime tube, stan's no tube, salsa tubes, every thorn resistant tube made "almost".
Bike Setup:2003 enduro 5in. travel all mountain gucci setup
Bottom Line:I'd have a good defense against the Mojave desert eating my tubes if they did'nt leak around the stem. I've found luck by using the slime tire liner in between the tube and tire but I need a good tube that will endure my riding conditions.
