Bike Rim Replacement & Rebuild Check
A 700c label cannot tell you the profile, brake track, drilling, ERD, wheel build, tire fit, or safe service route. Build the exact requirement first.
Build the rim check ↓
A focused decision path for this exact job. Verify fit and safety details against the current maker instructions.
15-field rebuild Check
Prove the bare rim. Preserve the whole wheel.
The checker can stop structural damage, redirect a complete wheel, reject a 700c guess, expose a seller conflict, preserve an owned rim, or show one exact part record. It never calculates spokes, prescribes tension or pressure, teaches wheelbuilding, or clears a wheel to ride.

Before buying
Inspect wheel damage first. Confirm the exact rim specifications and rebuild requirements before buying a replacement.
Five decisions a rim catalog cannot make
Choose job
Bare-rim replacement, complete-wheel replacement, diagnosis, and a new wheel design are different routes.
Identify
ISO, widths, profile, brake, drilling, valve, and ERD must come from exact current specifications.
Preserve
Hub, spokes, nipples, lacing, tire, frame clearance, use, load, and builder responsibility remain attached.
Source
If you already own the correct rim, you may not need another. Confirm conflicting specifications with the manufacturer and seller before buying.
Hard stop
A visibly damaged rim is not a shopping shortcut
Cracks, splits, a concave or failed brake track, carbon damage, severe deformation, damaged eyelets, hub damage, or multiple spoke failures route to whole-wheel assessment.
A dent, seam movement, repeated spoke breakage, corrosion, recurring tire seating problem, or unexplained air loss needs diagnosis before a bare-rim choice.
Do not ride to “see if it holds.” The exact wheel procedure or a qualified wheel builder must own rebuild, tension, dish, truing, inspection, and release.
This page supplies no carbon judgment, spoke length, lacing pattern, tension target, tire pressure, build instruction, durability ranking, or road clearance.
Source conflict
A current seller title and its own specification table disagree. That is a stop, not a coin flip.
WTB W020-0624: 28 holes in the title, 32 in the table
manufacturer specifications
WTB maps part W020-0624 to KOM Light i23, 700 / 29, 23-622, 606 mm ERD, 23 mm inner width, 28 holes, and Presta.
seller conflict
The selected Performance title says 28H while its table says Hole: 32. The variant was also back-order only at capture. It cannot show until the seller confirms and corrects the exact stocked record.
The checker keeps that option visible as a conflict case so an apparently attractive product cannot quietly bypass source agreement.

Conflict control
WTB KOM Light i23 manufacturer specifications ↗
WTB maps W020-0624 to 28 holes, 23-622 and 606 mm ERD. Maker data exposes the seller conflict; it does not authorize silently correcting the seller card.
