Schwalbe Rocket Ron XC tire review – our favorite all-condition race tire

Schwalbe’s Rocket Ron has been one of the best XC tires for ages, particularly as the front wheel partner to Racing Ralph. While Racing Ray has now replaced it for drier conditions, Rocket Ron is still a brilliantly versatile high-velocity tire for front or rear use all year round. That comes at a high price and relatively high weight, though, and we’d like to mix up the compound and carcass options more.

Design and build

With it’s mid height, wide spaced, angular blocks the Rocket Ron tread looks more like a trail tire than a typical XC design. The shoulder knobs are bigger and more angular than most too, with sipe slots on top to allow surface deformation.

The red stripe denotes the use of the Schwalbe’s hardest fastest Addix Speed compound. The stripe is also offset to the riders left to make it easy to check whether it’s fitted the right way round.

I tested the Super Race carcass which is the most supple construction option in the Schwalbe arsenal. it’s only got a thin strip of puncture protection under the crown of the tread and reinforcement right against the rim edge though. Despite that it’s still slightly heavier than the Super Ground option which has a full wrap of puncture protection and ‘Snake Skin’ carcass strengthening. That makes it one of the heavier XC tires around in the 29 x 2.35in size I tested, but comparable with 2.4in tires from Vittoria, Hutchinson, Pirelli and others. Rocket Ron also comes in a cheaper ‘Performance’ version too as well as an unprecedented range of sizes from 16in kid's size upwards. While it’s currently only for sale to the public in a blackwall version, skin wall Rocket Rons could be seen stockpiled in the pits for sponsored riders at the Mont St Anne World Cup race, so hopefully they’ll be available for mere mortals soon.

Performance

Having worked my way through a ton of different XC and fast trail tire options over the past couple of years, it takes a lot for one to make a significant impression. Where Ron wins though is by matching Rocket level speed to impressively tenacious grip in a wide range of conditions. The block-shaped, mid-height tread gives sharper, better supporting working edges compared to tear drop and paddle-style treads. There’s way more to work with than really low-profile ‘semi-slick’ designs too. Even with the hardest of Schwalbe’s Addix compounds grip in wet and slippery conditions is as good if not better as most other race rubber too.

The real surprise is while it growls and grumbles more than slicks or low-tread tires on tar surfaces, subtle ramping means it still rolls OK on the road. Get it into the rough and that ultra-supple Super Race carcass really comes into its own. With no big sheets of protective material in the mix, it’s free to flow and flux over roots, rocks and ripples rather than getting bounced and stalled. That lets Rocket Ron keep pace with tires that out roll it on the road and the rougher the terrain, the more that Schwalbe Super Race advantage becomes obvious.

As well as saving energy and maintaining momentum, that compliance also gives better traction, amplifying its mechanical grip even further. The carcass is still predictable at lower pressures too, rather than suddenly folding and flopping. Even at lower pressures it still feels alive rather than sluggish and while the weight dulls initial acceleration compared to superlight tires the overall vibe is definitely high velocity.

Another surprise from testing the Super Race carcass Rocket Ron, Racing Ray and Racing Ralph for a couple of years, and Super Race Wicked Will for a couple of months, is how survivable it is. While there’s very little protection built-in, the pliable character actually seems to dodge impact and scuff damage better than Super Ground tires. The only issue I’ve had is premature sidewall wear if used with a broader, harder type of tire insert such as Cush Core but that hasn’t caused any leaking. Better survivability increases value too, as does on-site event support at most major races in the UK at least, but it’s still an expensive tire that’s not often discounted.

Verdict

Rocket Ron has been around for a while but the latest carcass and compound tech means it’s still ahead of the game in techier, more slippery situations. The fact it gives you a grip advantage without obviously compromising speed or survivability makes it a truly stand out tire. Especially as the original Maxxis Forekaster which used to run it very close has now been replaced by a heavier, slower version. That said, I think using the slightly softer Addix SpeedGrip compound in the Super Race not just the Super Ground models would flatter the talent of the tread pattern even more.

Now Nobby Nic has become a more aggressive tire I’d love to see Rocket Ron on a Super Trail carcass for fast general use too. That’s definitely greedy though seeing as there are already so many versions of Ron available from tiny 16in to 2.8 plus sizes. That leaves only the price to really grumble about, but at least you’re buying a genuinely exceptional tire rather than paying more for meh.
