  • One again back to tyre topic, I want something quick on tarmac, but able for some detour on not-too-rough gravel as well.
    Gravelking (slick) 32c / Gravelking (slick) 38c / G-One Speed 30c
    Which one would you pick for tubeless running? I want some decent longevity (like not having to replace them after 2000 km) and puncture resistance, at least to level where sealant fixes any problems.
    Edit: It seems that GK32c are not TL ready, so the other two can still be considered.

  • the 30mm g one speed are great tires but imo don't have the volume for low psi required for gravel. If its light gravel you might be ok but i'd go with the higher volume g one speed if i were you.

  • G one speed

  • Generally I find them very expensive, 30c version was the only one I found with a more reasonable price (35 GBP at Wiggle + discount of 10 GBP for ordering first time), the wider ones are everywhere like 45 GBP or more.

    In the end I will probably get two wheelsets with the second one housing a knobbly tyre, but I would prefer to delay that expense for now.

  • How durable are G-One Speed? I found some reports that they wear pretty quickly.

  • They're fine for road use but take them off road and they wear pretty quickly and don't offer much grip in my experience.

  • Alternatively I could also consider G-One Allround 35/38c, as I see they are just a bit more expensive and still cheaper than wide G-One Speed.

  • Yep, I also have the allround 35c and they are good on and off road. Obviously a bit slower on road than the speed but not too much and give a comfier ride.

  • once the middle tread wears out on the allround do they go faster? can you comment on their longevity ?

  • Can't comment in the longevity of the allrounds I'm afraid. I guess mine have done around 500 miles and still have all their tread.

  • Have you used the Speeds? How is their longevity on road? And id you have 30c or wider ones?

  • And if considering the pure road use (and separate wheelset for gravel and dirt) would you go for G-One Speed 30c tubeless or tubed Michelin Pro4 Endurance 28c?
    One more alternative can be Maxxis Re-Fuse 32c or 40c. Actually they are the cheapest, just found a French shop (cycletyres.fr) where for 50 EUR I can get a pair including postage, so this seems very tempting. They are much beefier at 525 g though (40c, 32c is 390 g), will they be any quicker than my current Vittoria Adventure Trail 38c?

  • I only ride tubeless now so I would go with the G-one Speeds. I really like them and prefer them to my Hutchinson Sector 28s. I've no experience of Pro4s but I did run Pro2s years ago and really liked them.

  • double post to be deleted

  • I also really like tubeless after started with it in the current Vittorias Adventure. How do you find longevity of G-One Speed?

  • Not brilliant, not bad, but I've ridden them a lot on canal paths. I reckon I'll get around 2000 miles out of them. In comparison I'll probably get a lot more out of the Sectors but the ride isn't as nice.

  • Don't bother. Get the all-road for longevity. I've head to replace a few for long distance riders and they're amazing, but if you love the speed ones, prepare to change them frequently.

    Not that they suffer much when they wear the middle out mind you. I used a customers old ones, and still got another 2.5k out of them!

    But if you want fit, forget and just ride, get the all road.

  • If the XLA is like the XLS, be careful on max tyre clearance, you really can't go bigger than 33c on the XLS (even with 650b it'd be a struggle), it's built for racing.

    I can't see it mentioned in the description, where as the Full Monty says 40c and would be better for gravel duties.

  • Thanks for the reply, the low mileage of Speeds is exactly the thing that together with price stops me from buying them. Maxxis Re-Fuse seem very tempting at that 50 EUR a pair though. In the end I might just continue with Vittorias until I wear them out and then think about either G-One Allround or Gravelking SK as do-it-all tyre or buying a second wheelset to have separate road and dirt wheels.

  • once the middle tread wears out on the allround do they go faster?

    No.

    But they’re really fast. I mean close to a phat race tyre. Nothing like a touring tyre. More like a file tread cross tyre.

  • According to the spiel, they have increased the tyre and mud clearance on the SL. May drop them an e-mail re 650b, see what they say. I like the idea that its 'made for racing' as you say, rather than the Full Monty.

    I love my Soma GR, but thinking a 650b which is more aggressive (and cheaper/lighter!), could be fun too, and also something I can feel slightly less precious about.

  • Here is the XLS clearance with 33c, the frame doesn't widen much to allow for 650b to really work, hopefully this new SL has fixed that.

    Just realised it's a new model!

  • Re-Fuse don't compare. All forms of the G-Ones are so goddamned capable and fast. It's my favourite tyre and I'll scream and shout about till the sun rises. They're superb, but if I needed a do it all tyre, it'll be the all-road; the speed is so sticky/compliant/fast, but you do suffer in terms of longevity.
    I know they're expensive, but tyres are one of the few things I don't hesitate to spend money on; it's the only contact between you and the ground.

  • I see your point. It's a pity there are so few opinions on Vittoria Adventure Trail I currently use, it would be very helpful to be able to hear from somebody who has ridden both Vittorias and e.g. G-Ones. For now I feel they aren't the fastest for sure, but I got them free with a bike and they are tubeless ready, so I am tempted to just live with them and keep using and only switch to better tyre when they are worn out.

  • And when already talking about G-Ones, which size is better for do-it-all use, 35 or 38?
