Schwalbe

I had tried another vendor's TPU tubes that had metal stems, but those had serious air leakage problems, so I went back to butyl for a while. Then tried these Schwalbe tubes since I have had such good experience with their tires (road, gravel, and touring). These Aerothan tubes, even though they have plastic valve stems, have been working well for me for the past 3 months. No issues with durability in both my road bike and gravel bike.

A great all-rounder for city commuting, touring, and light gravel. Excellent puncture protection was my main reason for purchasing, particularly for battling goatheads here in New Mexico. Rolling resistance is relatively good, and the reflective sidewalls are a nice touch for added visibility around town.

They're not the most supple tires and have a somewhat stiff ride, but it's to be expected for the protection they offer. The folding version is likely worth considering for better weight and ride quality if you're willing to spend a little more. For a tubed setup, Schwalbe Marathons and Continental Top Contacts have been my go-tos. They're built to last!

As a year-round rider in Fairbanks Alaska this is the perfect tire for winter road and groomed trails here in Fairbanks but not without limited use. In the two weeks I have used these tires the weather provided the best test conditions ice covered and packed snow which these tires are designed for.

After seating in the studs in at a higher-than-normal air pressures I lowered them to 40 pounds as a starting point to dialing in the sweet spot and was completely impressed at the control I had on ice covered roads along with snow covered iced over pavement. Not by choice I was forced off the trail for a short, unplanned detour into slushy conditions, the tires-maintained controllable steering and traction that an experienced winter rider can handle. These tires do not give a rider the same rideability as a fat bike which is designed for loose and slushy snow conditions. these tires are designed for packed trails and road use.

Winter riding is not for everybody and takes experience and plenty of close calls as a norm, winter riding takes different skills such as not leaning the bike over too far when turning and extended braking distances. Wearing a helmet is not negotiable, normal bicycle helmets are not rated for cold weather they will shatter in extreme cold with the slightest bump, a good substitute is a lightweight ski helmet.

Winter riding has a big learning advantage, after one season of cold weather riding will increase your riding skills in more seasonable bike weather to a point one would be hard to believe. Not to mention the fun involved while learning if it's your first go at winter riding find an empty parking lot and have fun and be prepared to expect to fall a few times so go slow while learning.

Before anyone asks the cut off temperature for riders in Fairbanks is around 30 below zero F

these are the best TPU type tubes I have used - the patch system actually works well. When you get a punctures you find the hole, wipe and stick the patch on, done ant it actually seals the tube good as new. After trying several different TPU tubes including Pirelli, Ridenow, and some god knows what from Amazon these are my go to for road and gravel riding. Oh and BTD always get my order out in one day and Fed Ex ground from Portland to Eugene is overnight so its faster than expected delivery too.
