The Dia-Compe Gran Compe SF Hub is a small-flange hub from the Gran Compe series, designed for single speed bike wheel builds. It is suitable for riders who want a clean appearance, stable rotation and good value for custom wheel setups.
Gran Compe is one of Dia-Compe’s well-known component lines. The SF hub combines a simple appearance with practical specifications, making it easy to include in different wheel build budgets. It is a solid choice for riders building single speed wheels, upgrading existing hubs or planning a classic wheel setup.
The hub body is made from cold-forged aluminum, balancing everyday strength with a refined metal finish. The small-flange shape gives the wheelset a clean and classic appearance, while silver and black color options make it easy to match different frames and wheel builds.
The hub uses sealed bearings for stable and reliable rotation. The front hub uses 100mm O.L.D., while the rear hub uses 120mm O.L.D. The rear hub is available in a Fixed / Fixed configuration for common single speed drivetrain setups.
For spoke holes, the front hub is available in 20H, 24H or 32H, while the rear hub is available in Fixed / Fixed 24H or 32H. Riders can choose according to rim hole count, wheel build purpose and preferred riding feel, whether aiming for a lighter build or a more supportive daily setup.
If you are looking for a classic-looking hub with smooth rotation, practical specifications and strong value for single speed wheel upgrades, the Dia-Compe Gran Compe SF Hub is a worthwhile option.
⚠️ Please note: this product includes one hub only. Rim, spokes, wheel-building labor, cog, lockring and display props are not included.
⚠️ Before purchase, confirm front / rear option, spoke hole count, O.L.D. spacing and rim compatibility.
