Phil Wood and Hope Tech clamps are 31.8mm, the standard size on the vast majority of modern frames. White Industries makes theirs in 32mm, a less common size found on some specific frames. Always measure your actual seat tube outside diameter before ordering — a 32mm collar will not clamp properly on a 31.8mm seat tube, and vice versa.\u003c\/p\u003e\n\u003ch4\u003eWhich brand should I choose?\u003c\/h4\u003e\n\u003cp\u003eAll three are precision-machined and built to last. Phil Wood and White Industries lean more toward a showpiece finishing touch for a colour-matched build. Hope Tech's clamp has a larger clamping area specifically designed for dropper seatposts and comes in at a lower price point, making it a strong option if you're after function first.\u003c\/p\u003e\n\u003cp\u003eIt's also important to note that Phil Wood and White Industries seatpost clamps are 12mm tall whereas Hope clamps are 15mm tall. If you have a carbon frame with a recessed area at the top of the seat post tube, make sure to measure the height. If it's under 15mm, a Hope clamp won't fit properly.\u003c\/p\u003e\n\u003ch4\u003eCan I get a colour or size that's not listed?\u003c\/h4\u003e\n\u003cp\u003eYou sure can!

This component is created with the same attention to detail that's made White Industries parts a fixture on serious builds for decades.\u003c\/p\u003e\n\u003cp\u003eThis seat post clamp is precision-machined from 6061 aluminium to provide secure, consistent clamping with clean lines and long-term reliability. Machined and polished edges reduce excess material while protecting your frame's paint or finish. An oversized stainless steel bolt gives you a confident, secure hold without adding unnecessary bulk or weight. You get a clean, scratch-free fit that holds its position ride after ride. This means no creaking, no slipping (a common issue with lesser-quality seat collars) and no drama.\u003c\/p\u003e\n\u003cp\u003eBut function is only half the story.
