Long-term reviewOwner review

Краткий обзор нового карбонового гравийника на раме spcycle g028 и с трасмиссией sram rival 1×13

Russian owner's 800 km review of a size L SPCYCLE G028 built with SRAM Rival XPLR 1×13 (Russian, automatic captions).

zzefol · 2026-10-04. Owner review of a self-built bike after about 800 km; no sponsorship is stated. Disclosure basis.

Takeaways

  • Fit check1:37The maker claims up to 57 mm; with 48 mm tires on 23 mm-internal wheels the owner showed ample room and expects 55–57 mm to fit (Russian, automatic captions).
  • Fit check3:09With a 170 mm SRAM crank and 40T ring the chainring touched the frame during assembly; a 165 mm crank of the other version fitted.
  • Build note5:58Plenty of mounts including under the down tube; a standard frame bag would not fit around the top-tube shape, so he bought one that straps to the top-tube bosses.
  • Measured6:39The size L build with Rival XPLR 1×13 weighed 8.8 kg without bag, lights, mudguards or bottle cages.
