Hope - Sadelklämma med en skruv

Hope's bolted collar is super simple in operation, but with just enough lazer etched detailing to add that vital bike jewelery element. With the steel bolt threading directly into the alloy collar, tighteneing needs to be careful though, so it's best used with an accurate seat post/seat tube fit...weight is an impressively low 20g though, and it comes in a full range of sizes.

Pretty seat tube necklace, but limited tightening pressure

Cool clamp jewellry that actually holds your seatpost in place
