Schwalbe

I've been using these tubes on my go-to road bike for about 1.5 years now, and overall, I really like them, and will continue to use them. They're reasonably light, roll very nicely, and are quite puncture-resistant.

However, I do not quite trust the valve cores. They are loose when they come shipped, and you have to tighten them before the first use, which is not a deal-breaker, but still worth noting. I use Leyzyne pumps, which are threaded, and with these tubes you need to quickly re-tighten the valve cores every time you inflate your tires, which, again, is not a deal-breaker, but still annoying. I have not yet had a valve failure, but these things are apparently 3-D printed, not metal, and I can imagine a total valve failure happening if you're not attentive.

If they came with non-removable valve cores, I'd be a lot happier with them, but, overall, they're very good: they perform almost as well as latex, but are even lighter, and they're more durable and retain air better than butyl tubes.

What can I say that hasn't already been said about these very durable tires. I rode across the country (on the ACA TransAm trail) on these tires without a single flat! I use it on all my bikes because they are extremely flat resistant and they last a long time. They do run on the "heavy" side, but the durability and longevity they provide is a tradeoff I can easily live with (I'm obviously a "tourist" and not a "racer"). I much prefer this solution to the mess and hassle of tubeless tires.

I put these on my gravel bike - Trek Checkpoint, DT-Swiss Wheels, 700C X 45 mm. I set these up with TPU tubes because I don't want to deal with the tubeless mess + I only ride my gravel bike about 20 times per year (only in the winter). I ride at 30 PSI (165 lb). No issues with pinch flats. Great grip on gravel and mud as the tread is soft and supple. Also, it's fast on smooth tarmac - almost as fast as my road bike (Cervelo Caledonia with Elite Wheels + Conti GP 5000 (32 mm) + tpu tubes).

February 2021 I bought a Trek Verve +2 E bike and Immediately bought two Schwalbe Marathon E Plus 700c tires from Bike Tires Direct to replace what came with the bike. This year (2025) I'm replacing my rear tire after 12,300 miles. The thread is still good. I never had a flat. It was just beginning to flatten out. Highly recommend this tire!
