That difference is caused by the gearing: in a large gear the cranks barely have to move before the freehub engages, whereas in a small gear there’s much more movement at the cranks. At 10 degrees, it’s not super fast and wouldn’t be sufficient on a mountain bike, but it’s not caused me any problems or prevented me from cleaning a climb on my gravel bike. Here the low weight is naturally a great help, but it’s also a test for the freehub engagement too. ![]() Balancing the rear wheel grip and sudden changes of line means sometimes coming to an almost complete stop and then accelerating up the sketchy bit. Going back up the hills, selecting steeper climbs ticks off the elevation more quickly, but does mean the challenge can be as much technical as physical. But they’ve stood up well, with the only evidence being tiny, superficial marks to the finish. Whilst I haven’t bottomed out the tyres on any square-edged hits, I have been hearing the hollow 'thunk' of rocks bouncing up and smacking against the profile of the rims as they ping out from under my tyres. The hills of South Wales have been a pretty brutal testing ground, with the terrain being quite loose and rocky in sections. Even with a set of much wider tyres, the total system weight of the Scribes was still lighter – making the bike quicker to accelerate and easier to handle – while also providing the benefits of increased comfort and grip. Of course, the difference being that I was travelling further and faster per pedal stroke with the Gravel Wide++ wheels.Īgainst a set of Miche Carbo Graff gravel wheels – which sit about as far over a grand as the Gravel Wide++ sit under – the difference was still very marked. The sensation of setting off was like being in a significantly lower gear, needing that much less torque at the cranks to get the wheels spinning. Immediately from the first pedal stroke, the acceleration was instantaneous. Although naturally not particularly light, they didn’t deaden the ride or ever feel like a drag.Įven so, it was like night and day coming to the Scribe Gravel Wide++ wheels. I’d be finding these perfectly fine: durable and robust, I had no qualms or reservations about ploughing them through the winter. The bike I swapped these wheels into was previously running a set of alloy DT Swiss gravel wheels. There might be some tyre combinations that don’t play well but those Schwalbes tend to work well on most rims, so that is a good sign. I did use tyre levers to mount the G-One Bites, but that was more out of laziness rather than any particular need. EXP 54 - Upgraded from EXP 36 to gain incredibly faster engagement.Setting up the wheels, they’ve proved a good match with both a set of Schwalbe G-One Bites and a pair of American Classic’s new Krumbein tyres.EXP 36 - With only a singlel spring, making the hubs faster and lighter, more complete engagement of the 36 ratchet teeth for more precise contact, and therefore a longer lifespan.54T - Super fast engagement, but shallow teeth require more careful re-greasing and the thru-axle should be checked every ride.36T - Happy medium, doubles the engagement points.18T - Deepest teeth, slowest engagement, least amount of maintenance, suitable for powerful riders.If you want to know more about DT Ratchet System,watch the DT Swiss video below.ĭT Swiss hubs use star ratchets and are available in 3 different models with varying points of engagement. You will find more every day whether you are quartering, cornering, sprinting, or even just setting off a smaller engagement angle will help you out. These are just 2 small areas where a small engagement angle will make cycling safer or a bit easier. The smaller engagement point will allow you to surge forward and hopefully avoid a potential crash. ![]() You are now on your mountain bike, you are in some really technical terrain and almost stalled. You will be saving small bits of energy all the way up a climb. ![]() You press your pedal, and you have 20° of movement before your effort starts to move your wheel, or you have 6.6° of movement. Imagine you are on your road bike and you are climbing a famous climb, you are suffering and just come round a hairpin.
