Harrison H.wrote a review of Cutter Cutter X-Wide Heavy Duty 26" MTB Tubes - 4 Pack on July 16, 2011
Great if you ride downhill and havent switched to tubless yet. pretty heavy, probably the beefiest tubes ive ever seen, and definetly the widest. major difference in cornering from standard sized, bike shop tubes. Probably not for you if you arent running over 2.50's. or if you ride XC. Helped my cornering out big time, and gunna ride them till i go tubless!
