Why WHEELTOP Stands Out

| Max Cassette Size - 52T | Max Cassette Size - 36T |
| Capacity - 800 mAh | Rated Capacity - 500 mAh |
| Exclusive Shark-Fin aesthetic design, combining style and aerodynamics | No distinctive exterior design features |

“The truth is, I'd never tried this kind of gearing before. The way it shifts the entire cassette in one go when you hold the lever is spectacular. I was really impressed by that feature.”

“WHEELTOP EDS Gex – WHEELTOP’s first gravel-dedicated, fully wireless component. I’ve been running this on my Dolan gravel bike since last October. I have totally abused it, I have not cleaned it, I have not charged it, and it has not missed a beat, it is perfect, very impressive！”

“It really wins in terms of that unmatched multi-gear versatility and just straight-up value, 'cause there's nothing close at the moment for what is a perfectly functional wireless groupset — one that shifts as well as you can expect, for whatever chain and cassette setup you're running, and also brakes perfectly adequately as well.”

“As for the brakes, I thought they would be out of whack but as you can see there is no rubbing whatsoever, it works very well and has a feel to it that I really like, it's very adjustable and I think it's very good.”

“Through my testing so far there's no issues with it the shifting is very precise obviously because it's electronic you can fine-tune the trim for every individual cog and if you take the time to do that the shifting is absolutely perfect!”

“I never been that excited about the wireless driverain revolution especially, because of the high cost up front. But after only a couple of rides with WHEELTOP GeX drivertrain. I think I might have changed my mind.”

“Completely top-notch, and it really performs well. I have to say, I’m very impressed. This gear shift works very smoothly, and with brakes that have spectacular braking power, I believe.”
