Stuff Cutter X-Wide Heavy Duty MTB Tubes in your pack and be the hero when the sun’s quickly setting and the group lagger flats with no gear. Extra thick for downhill reliability, the Cutter HD rubber will get you back to the truck before the sun drops and you’re stuck hiking out by brail.
I have been using these in my dirt jumper all season and so far I have not had any issues with them. I have had several goat head thorns in my tires and not one flat from them, however I do run a heavy duty tire on my bike which is likely the reason the thorns have not penetrated the tubes. These weigh in at 229.5 Grams which is the same as the standard wide tuber from cutter and these somehow manage to have a longer valve stem at 6cm long. These are thicker than the standard tube and offer slightly more pinch flat protection than the standard tubes. If you are looking for a light weight cross country tube look elsewhere. If you are not worried about weight but are looking for a good value then you can stop looking and get yourself a 4 pack for a killer deal. Now get out there and enjoy the trails!
Bought a whack of these this spring - all of my friends are riding them now. I've run them super-hard in 2.5" Maxis DH tires -- no flats all summer :-)
We often ride in a super-rocky terrain - our best trails are rock-fests - and as long as I run Mfg. recommended tire pressures I can ride as hard as I like without flats. I'm on the larger size of the scale; 215 lbs, an experienced / aggressive rider on a six inch travel 'all-mountain' bike (Blur LT with Fox 36's). The valve stems are on the longish side, but its made absolutely no different to product reliability / durability.
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!
I hate the stems on these. I don't mind Presta valves, but the valve stems are really stall and don't have the little nuts on them that keep them locked to the rim, that makes them difficult to inflate. I also feel that the presta valve inside bends easier than other tubes, so they break easily internally.
Giving it four stars mainly because of the price (sale price).
Not the best tubes I've ever used though. Downhill biking and jumping, my roommates and I went through a couple packs pretty quick.
That being said, I'd still buy them again.
i do not recommend these tubes for freeriding or DH.... More like a heavy duty XC tuber...
These tubes are a really good value. Especially considering that thick tubes can be almost 20 bucks a piece at a lot of places. The only problem I have had is that over time it appears as if some of the seams on the tube start to separate.
