Overview
A chromoly steel frameset for 451 rim builds using traditional caliper brakes and quick release hubs, sold in 42cm or 44cm sizes. It pairs with a 1-1/8 inch head tube, 27.2mm seatpost and a 68mm threaded bottom bracket, and ships in rose gold, champagne or gunmetal gray.
Where a thru axle disc brake frameset targets newer builds, this Hwevdhj frame is built for the older caliper brake and quick release standard, common on lighter small wheel road conversions. The two sizes differ mainly in weight, about 2800g for the 42cm and 2860g for the 44cm, so matching the right size to the rider matters for fit.
- 451 rim frameset in 42cm or 44cm
- Cr-Mo steel frame and fork
- Quick release F100mm / R130mm dropouts
- 68mm threaded bottom bracket, 27.2mm seatpost
Who it's for
Builders assembling a 451 rim bike around standard quick release wheels and caliper brakes, who want steel's durability over carbon and a specific frame size in 42cm or 44cm.
Pros and cons
- Two frame sizes, 42cm or 44cm, to match rider height
- Three color options: rose gold, champagne, gunmetal gray
- Complete fork, headset, seatpost and clamp included
- Steel construction is more repair friendly than carbon
- C brake only, no disc brake mounting
- Quick release axles are less stiff than thru axle
- Max tire width of 25C limits wider builds
Performance notes
Chromoly steel adds weight next to a carbon frameset but tends to hold up better under repeated stress and is easier to repair or repaint. Max tire clearance is capped at 25C, so this frame suits narrower tires rather than a fat tire or gravel build.
