what headset does the ripley sl use

The Ripley SL is listed with a Cane Creek 50 IS41 / IS52 headset in retailer specs.

What that means

That’s the headset model shown on a Ripley SL build page, so it’s the safest answer for the stock spec.

Quick note

Different build kits or custom builds can swap small parts, but the base listing points to that Cane Creek headset.
