This H32-W32 wheelbuilding kit is designed for riders and wheelbuilders who want maximum weight savings without compromising on high-quality components.
The foundation is formed by ultra-light H32-W32 carbon rims weighing approximately 285 grams each. With a rim depth of only 32 mm, rotating mass remains extremely low, while the 32 mm external width and 24 mm internal width are well suited to modern wider road tyres.
Combined with the OGS Ultra Light carbon spoke hubs, Alpina Carbolite carbon spokes and lightweight nipples, the complete wheelset weighs approximately 888 grams with SRAM XDR freehub body.
The very low rim weight provides rapid acceleration and a direct riding feel during climbing, sprinting and frequent changes in speed. The 32 mm rim depth is also less sensitive to crosswinds than deeper aero wheels.
The rims are specifically developed for carbon spokes and use 20 spoke holes per wheel. The kit includes a total of 40 Alpina Carbolite carbon spokes in 296 mm length.
The Alpina Carbolite spokes use titanium ends and a T-Head Straight Pull interface. This construction helps prevent the carbon spoke from twisting while tensioning and keeps the aerodynamic profile correctly aligned.
The OGS Ultra Light hubs weigh approximately 229 grams per set and use high-quality TPI ceramic bearings combined with a 36T ratchet system.
The result is an extremely lightweight wheelbuilding kit for racing, climbing bikes and premium custom wheel builds.

EXTREMELY LOW WEIGHT – APPROXIMATELY 888 GRAMS
The most impressive feature of this configuration is its complete weight.
With a SRAM XDR freehub body, the complete built wheelset weighs approximately:
±888 grams
This includes:
• Front wheel
• Rear wheel
• H32-W32 carbon rims
• OGS Ultra Light hubs
• 40 Alpina Carbolite carbon spokes
• Nipples
• SRAM XDR freehub body
By reducing weight primarily at the rim, rotating mass is kept extremely low. This is immediately noticeable during acceleration, climbing and repeated changes in speed.
Actual weight may vary slightly due to production tolerances of the individual components.

• Good transition between tyre and rim
The rim is particularly suitable for modern road tyres from approximately 28 mm upwards, depending on tyre model, pressure and frame clearance.
32 MM RIM DEPTH
This wheelset focuses on low weight, fast acceleration and control.
Benefits of the 32 mm rim include:
• Very low rotating mass
• Rapid acceleration
• Direct riding feel
• Reduced sensitivity to crosswinds
• Ideal for climbing and hilly courses
• Suitable as an ultra-light all-round wheelset

• Straight Pull T-Head carbon spoke interface
• 20H front
• 20H rear
Available freehub bodies:
• Shimano HG
• SRAM XDR
• MSR
• Campagnolo N3W
The stated complete wheelset weight of approximately 888 grams is based on the SRAM XDR version.
TPI CERAMIC BEARINGS
The OGS Ultra Light hubs use high-quality TPI ceramic bearings.
These bearings are designed for smooth running and low resistance and match the high-end character of this wheelbuilding kit.
ALPINA CARBOLITE CARBON SPOKES
The kit includes Alpina Carbolite Straight Pull carbon spokes.
Specifications:
• Spoke material: Carbon
• Ends: Titanium
• Interface: T-Head Straight Pull
• Profile: Aero
• Spoke length: 296 mm

The T-Head design helps prevent the carbon spoke from twisting during wheel tensioning.
OPTIMISED SPOKE LENGTH
This H32-W32 rim and OGS Ultra Light carbon spoke hub combination uses one spoke length:
Spoke length: 296 mm
A total of 40 spokes is included:
• 20 spokes for the front wheel
• 20 spokes for the rear wheel
Using a single spoke length simplifies inventory and makes the wheelbuilding process easier.
Rim NSD: 577 mm
