Wheels Mfg. Seatpost Collars are CNC-machined in the US

Last week Wheels Manufacturing may have lured us in with the hope of joining their elusive Random Derailleur Hanger of the Month Club, but this week, they have more practical machined aluminum goodies for us. Of course, from a more practical derailleur standpoint, Wheels Mfg. does also machine their own colorful all-aluminum UDHs and even Shimano Direct Mount hangers for UDH-equipped road, gravel & mountain bikes. Back to the seatpost collars though…
I’ve had both ultralight and super-budget clamps fail on me in the past, so this is one place I never want to skimp on strength and durability. And these new Wheels Manufacturing Seatpost Collars look like they deliver on lightweight, affordability, and a robust design.

They describe them as an ideal blend of “simplicity, style, and rock-solid performance“. There’s not much I can add to that other than that I am surprised that Wheels Mfg. manages to machine these in the US, offer them in three sizes to fit most conventional seattubes at weights from just 31g, and offer them in a rainbow of 7 bright colors for just $25.
If you have an external seatpost collar that you aren’t 100% satisfied with, or you just want to splash a little color onto your bike, these seem like a no-brainer.

Befuddled by so many seatpost sizes?

Most modern bikes with round seatposts have settled on just a handful of common sizes – you’re mostly safe with 27.2, 30.9, 31.6 & 34.9, these days. But if you need to figure out the seatpost size on several bikes, it can be a little tricky. So Wheels Manufacturing also made this simple, low-cost seatpost size gauge – for pro and DIY home bike mechanics. For just $10, you drop this acrylic jobber into the seattube and you’ll know exactly what seatpost you need – 24 common sizes from 25.0mm all the way up to 34.9mm.
