Our review

A functional bit of kit at a good price. The large lever has its benefits but doesn’t look great

The Jewel’s massive paddle-like lever makes clamping your seatpost easy – you’ve plenty to push against without hurting your hand. The price is great for its good finish and the 50g weight isn’t too bad either.


Although there are benefits to the large paddle-like lever, it isn’t pretty. Shaving it down slightly would make it less bulky and wouldn’t affect performance too much. It’d drop a few grams too. A tool-free tension adjuster would also be a bonus.
