Description
The AL25 is Aforce’s lightweight road rim, developed alongside the deeper AL33 for riders who prioritise low weight over aerodynamics. At 25mm deep and 21mm internal width, it suits 25–32mm road and fast endurance tyres well, and is tubeless ready throughout. It is not a gravel rim — the internal width and profile are optimised for the road end of the spectrum.
This is the disc-specific variant, and it is asymmetric; an important structural detail. The spoke bed is offset to compensate for the geometry of disc hubs, where drive-side and disc-side spoke angles differ significantly. Built correctly, noting that front and rear require opposite orientations the result is unusually well-balanced spoke tensions for a disc wheel. In our own test build against a BX106F hub, disc-side tension measured 110kgf with the non-disc side at 100kgf. That’s a differential most symmetric rims can’t approach on a disc build. The recommended tension ceiling is 110kgf; additional tension is unnecessary and adds stress to the spoke bed without any structural benefit.
External nipples make truing and tensioning straightforward with standard tooling, with no need for an access hole in the rim bed.
Who it’s for: Weight-conscious builders putting together a tubeless-ready road or fast endurance disc wheelset. The 24h option suits lighter riders or those wanting the leanest possible build; 28h gives a more conventional road wheel with a little more robustness.
Who should look elsewhere: Riders wanting a wider internal width for 32mm+ tyres or mixed-surface use, the DCR range is better suited to those applications. If you want the Aforce profile with more aero depth, the AL33 is the natural step up. If you prefer internal nipples, the same rim is available in that configuration.
