Ultimate Sports Engineering (USE) was founded in 1990 and is renowned for the suspension seatpost (winning Olympic gold, King of the Mountains at the Tour De France) USE is based in Bury, nestled in the heart of the South Downs National Park. How I got here (at Cane Creek): Feeling pretty unfulfilled with a corporate engineering job, I happened to see that Cane Creek was hiring.

I understand there is no official standard for seat post size but I'm hoping manufacturers agree the way forward. Machined Aluminium shim - machined to very high tolerances from 6082 T6 Aluminium and then black anodised to protect from corrosion.These useful extra long (100mm) precision cnc machined alloy shims allow the use of a smaller diameter seat post inside a larger diameter seat tube on a frame. Our Seatpost Adapters are made of premium quality aluminum and have been manufactured within stringent tolerances to match or surpass the highest quality standards. Machined Plastic shim - larger size shims are machined to very high tolerances from "filled" engineering thermoplastic UPVC. Our Seatpost Adapters provide the opportunity for riders to tune and adjust the compliance of their ride. were fairly common in the early days of commercial mountain biking, because companies didn't put frames together with Reynolds tubes, for the most part.

just wondered if there's any reason to avoid doing this as obviously a shim is never ideal but I cant see it doing any harm but my frame is carbon so don't want to do any damage, although my current dropper is an old 27.We'll try to get back to you within 14 working days of receipt of your parcel, although during busy periods this may take slightly longer. These guys are creative and innovative, even if parts are no longer fit for bikes, they will create something awesome!

We strive to help the environment by working with our suppliers to improve recyclable product packaging. Any of our old bike parts that we cannot use or sell on our recycled page we donate to this awesome initiative. Credit subject to status, UK residents only, Wiggle Ltd (In Administration) acts as a broker and offers finance from a restricted range of finance providers.If your shim is of high quality, good depth, and machined to high tolerances there really should be no issue using one.
