Review for the 38mm Schwalbe Pro One TLE tire. I installed a 38mm Pro One TLE to replace a worn 34mm Pro One TLE on my Specialized Turbo Creo e-bike that I use for work commuting, which is a 48 mile round trip commute. The extra 4mm width added some comfort/cush to the stiff riding frame. Commuted 1500 miles on this (rear) tire with no issues. Held air just fine and no flats in over 1600 miles commuting. Some conditions include sticks/twigs/debris on a canopy covered trail. Tire is starting to square off but after 1600 miles w/ average speed at 21.3mph with the power of an e-bike, I'd say this tire handled it just fine.

Happy with the purchase, Now that I have ridden these for a bunch of rides, mostly in the wet and soggy days of Portland Oregon. They really track well on our soft, soggy, mushy routes. Have not had any slips or slides, they rail the turns, stay planted on climbs, even on the short punchy ones out of the saddle. I usually ride a few miles to the off pavement area's, and do not find them to be draggy, I thought they would be, but I'm impressed. This is kind of an update from early November 2025.

Excellent tires- I opted for the 50mm size and couldn't be happier. Have about 500mi on mine, so time will tell about durability, but they seem great so far. Supple, very quick rolling, and reasonably grippy on all but singletrack/loose leaves/super chunky gravel.
I raced these in a gravel race where numerous folks running the G-One RS flatted, and I had absolutely no issues, so I have to believe the added center knobs help slightly with puncture resistance on sharper gravel.

I've used various tires over the past 9 years for gravel and have since switched over to mountain bike XC tires for most of my gravel needs as they are simply superior in pretty much every way. However, I wanted to try these tires out (along with the G-One R in 45mm which I'm less impressed with), so I grabbed a pair of these in 50mm. The RX's are very fast in a straight line. I'd put them on par with my Race King 2.0's on the straights.....however, for my terrain (Sonoran desert single and double track with varying degrees of sand over caliche and rock), the Race Kings/XC tires grip far better in the turns than gravel tires do. Now, if you're mostly going in a straight line and the terrain isn't too technical/chunky/demanding (think something like BWR Utah, which I would definitely use these RX's on) and your frame maxes out with 50mm tires, these tires would be a good option. Got them on the rim very easily, although I had to use an air compressor to get one of them to seat......easy peasy with the Park inflator head, my single best tubeless upgrade/tool. The QC at Schwalbe could be improved though as one tire weighed in at 630 grams and the other was 670 grams. Not sure why there was such a large discrepancy. They ride and roll well though, very comfortable. They don't have the cornering confidence of my Race Kings, but "gravel" tires are generally always a performance tradeoff trying to balance pavement and gravel/dirt road performance. When I'm blasting through non-technical singletrack with cacti lining both sides of the trail, cornering grip becomes exponentially important as running into a cactus (especially cholla) sucks a lot. If you're lucky enough to have dirt trails and no real consequences for sliding out in turns where you live, the cornering grip will probably be halfway decent for a gravel tire. They are a bit on the pricey side though, would be a good deal if they were about $25 less expensive.
