What to Compare Before Buying
- Clamp size: The stated size is 34.9 mm, with an additional 31.8 mm and 34.9 mm inner diameter reference elsewhere in the page. Match the clamp size to your bike frame or seat tube before ordering.
- Pack quantity: This is a 2-piece set. Check whether you need one clamp or a pair.
- Closure style: The quick-release design gives a different feel from a standard bolt-only clamp, so compare it with the fitting you want on the bike.
- Material: The clamp is described as aluminium alloy, which is a useful check if you are replacing an existing part and want a similar finish or build type.
Compatibility, Size and Fit
This clamp is described for mountain bikes, road bikes and folding bikes, and the wider wording also mentions MTBs, BMXs and DH bikes. The most important check is the stated 34.9 mm size, together with the extra 31.8 mm and 34.9 mm inner diameter reference. Because seat tube and seatpost clamp sizes must match correctly, confirm the measurement against your bike before choosing an offer.
Before You Decide
Confirm the 34.9 mm size against your bike, and check whether the 2-piece pack is the format you need. If your bike uses a different clamp size, this set will not be the right fit. The quick-release design and aluminium alloy construction are the main other points to compare before buying.
