SPCycle G028 new gravel frame with 57mm tires clearance

The SPCycle G028 is a new carbon gravel frameset offering massive tire clearance up to 700x57C or 29x2.25 inches, making it suitable for monster-cross or drop-bar MTB builds. It features Toray T1000/T1100 carbon, T47 threaded bottom bracket, UDH hanger, full internal routing, and flat mount disc brakes. Frame weight is around 1000-1050g (size M unpainted) and fork ~450g. It has passed ISO 4210 testing. Sizes M and L are available now; S and XL expected mid-May 2026. Pricing is competitive: available on AliExpress for around $739-924, or from the SPCycle website for about $628 including DDP shipping. The frame can be ordered without rivets on fork/seatstays upon request. Multiple metallic colors are offered. However, some users have reported quality issues including fork defects (undersized dropouts, delamination, rough finish), paint overspray, and orange peel. Communication with the seller can be slow. The frame has a BB drop of 80mm, which may require large tires to avoid pedal strikes. The fork lacks fender mounts (only cage mounts), limiting full fender use. Despite these concerns, the frame has seen significant sales and early builds are appearing.
