I run this tire as a front tire on my Aspero Gravel Bike. I initially bought the 40 mm as most of the riding I do has a good deal of asphalt. The G-one R is has just enough bite on most gravel to keep control and also maintain efficient rolling on asphalt. As a front tire the ware is very acceptable. I am not sure I would run as a rear tire but I imagine it rolls equally well and but likely faster ware. This tire will work well for category 1-3 trails. On looser terrain, some care is needed and lower air pressure. Once my 40 wares out, I already have a 45 to replace it.. I feel its a great tire for most of my needed. If more of my routes had looser terrain I would lean more towards the G-one X or consider something else.
What Impressed Me
Outstanding grip on technical terrain, even in slippery and loose sections
Efficient climbing without excessive rolling resistance
Stayed responsive in extreme cold when many tires harden up
No flats or significant wear despite rough abuse
Consistent performance from mile 5 to mile 40
The Downside
Higher price point, but the performance justifies it.
Verdict: Highly Recommended
Terra Speed tires deliver when conditions get tough. Perfect for serious gravel racing.
As others have mentioned, clogs my stems quickly, does not last very long. I've gone back to primarily using Orange Endurance sealant. I think this would be best used for a big event where you need good sealing for a short period of time. Big fan of other Silca products, think this is one I won't use anymore once I finish.
Installed on my Canyon Grizl CF SL 8 with 24mm DT Swiss GT1800 Spline wheels as I wanted a less knobbly option for a long road bikepacking trip. The run at ridiculously low pressures. Over a few hundred miles they've ridden great with no punctures.The tan walls look fantastic. But, oh my goodness, these were a pain to install. My thumbs were aching after levering them on millimeter by millimeter. If I have to pop a tube in on a long ride, I'd be quite worried.
