Short answer
A 22.2 mm bar is inside the ranges CatEye lists for its H-34N bracket (22-35 mm), Knog for the Blinder 1400 (22.2-35 mm) and SP Connect for its Universal Bike Mount (about 20-44 mm). It is below Quad Lock's 25-40 mm Handlebar/Stem Mount range, where Quad Lock points to its zip ties. Measure your bar where the clamp will sit before you buy.
Key facts
- How to check yours
- Measure where the clamp will sit, in millimeters, because makers state their ranges that way (CatEye's H-34N: 22-35 mm). Use a caliper, or wrap a paper strip around the bar, mark the overlap and divide that length by pi (3.14).[1]
- Mounts whose maker range includes it
- CatEye H-34N headlight bracket (22-35 mm); Knog Blinder 1400 bar mount (22.2-35 mm, the bottom of its range); SP Connect Universal Bike Mount (about 20-44 mm).[1][2][3]
- Mounts that do not list it
- Quad Lock's Handlebar/Stem Mount is designed for 25-40 mm. Wahoo's BOLT 3 / ROAM 3 out-front mount is for 31.8 mm round bars.[4][5]
- Shims, straps and adapters
- Quad Lock secures its Handlebar/Stem Mount with supplied rubber O-rings and nylon zip ties, and says the zip ties can fit most tubes outside 25-40 mm. SP Connect includes one flat and one round diameter adapter.[4][3]Quad Lock's 'most tubes' is not a guarantee for your bar.
- Devices and lights
- CatEye lists the H-34N for its AMPP, GVOLT, Sync Core, GE100 and HL-EL160/135 lights, but not AMPP models with rubber strap mounts. Knog's Blinder 1400 clamps with its own mount.[1][2]
- Not confirmed
- No source we read says where on a bar, or on which bikes, 22.2 mm is found. Peak Design's bar range for the Out Front Bike Mount V2 is not stated on its page.[6]
Watch out for
- 22.2 mm is below Quad Lock's 25-40 mm Handlebar/Stem Mount range; Quad Lock's 'most tubes' zip-tie wording is not a guarantee for your bar.
- At 22.2 mm the Knog Blinder 1400 is at the very bottom of its 22.2-35 mm range, so measure carefully.
- CatEye's H-34N does not take AMPP lights that use rubber strap mounts.

Questions
Will a Quad Lock handlebar mount fit a 22.2 mm bar?
22.2 mm is below the 25-40 mm range Quad Lock states for its Handlebar/Stem Mount. Quad Lock says its zip ties can fit most tubes outside that range, which is not a guarantee for your bar.[4]
Does the Knog Blinder 1400 fit a 22.2 mm bar?
Knog lists a 22.2-35 mm bar mount, so 22.2 mm is at the bottom of its stated range.[2]
How do I check that my bar is 22.2 mm?
Measure where the clamp will sit with a caliper, or wrap a paper strip around the bar and divide its length by pi. See how to measure your handlebar.
