SC1 seat clamp

A 31.8mm clamp CNC-machined from 2014-T6 aluminium, with a stainless steel bolt that holds. Anodised finish. Minimal in size, loud in presence.

Will it fit my bike?

  • Yes on any frame whose seat tube measures 31.8mm on the outside at the top, whatever the brand. That is a common size on mountain bikes, hybrids and many urban bikes.
  • Yes on the Collective C100 V3: a straight swap.
  • How to check: look for the size printed on your current clamp, or measure the outside of the seat tube just below it. Other common sizes are 34.9mm and 36.4mm, which need a bigger clamp.
  • Not for frames with an integrated clamp (common on BMX).

Colours

Black, chrome, gold, purple and oil slick. Run it to match an HX1 headset, Hub 2 or PX1 pedals. Pair it with a new seat from Bike Seats, or shop all MTB Parts.
