Seatpost Clamp Sizes and Quick-Release Upgrade GuideUpdated an hour ago

Seatpost and clamp sizes by model

The right clamp size depends on which generation of Vvolt ebike you have.

Second-generation ebikes (Alpha 2, Alpha 2.1, Centauri 2):

• Seatpost diameter: 30.9 mm
• Seatpost clamp size: 34.9 mm

First-generation ebikes:

• Seatpost diameter: 27.2 mm
• Seatpost clamp size: 31.8 mm

Slice Lite:

• Seatpost clamp size: 30.9 mm

Upgrading to a quick-release clamp

We recommend the Wolftooth Components quick-release seatpost clamp. It's a high-quality, tool-free upgrade that makes saddle height adjustments much faster.

Make sure to order the correct size for your model using the chart above.

Installation tip for second-gen bikes

If you're installing a quick-release clamp on an Alpha 2, Alpha 2.1, or Centauri 2, be aware that the rear light wire runs through the seatpost. You'll need to carefully remove and reinstall this wire when swapping the clamp. Take your time with this step to avoid damaging the wire.
