The Spcycle G028 is a carbon gravel frameset with huge tyre clearance (700x57C / 29x2.25in), modern standards (T47, UDH, full internal routing, downtube storage) and a smooth, stable ride, sold at a low price and also rebranded as Mondince FM346 and Meinier GRL15/17. Owners praise its value and versatility, but early forks had serious cosmetic/structural defects, the seatpost wedge bolt loosens, road cranksets need spacers, and paint/finish and customer service are inconsistent.
Pros
- Huge tyre clearance: 55-57 mm measured with 5-8 mm to spare, also with GRX 2x; 2.25 MTB tyres fit12
- Good value: about $638 including shipping, tariffs and metallic paint; about EUR 500 with cockpit1
- Modern standards: T47, UDH, full internal routing, ISO 4210 tested1
- Smooth, solid and still fast ride, praised for stability on and off road1
- Works with many drivetrains: SRAM wide and road cranks, GRX 2x, Wheeltop, mullet setups1
- Recent frames arrive clean, with faced BB and brake mounts and tidy headset seats1
- Custom paint and options such as no rivets or no fork mounts on request12
- Sold under several brands (Mondince FM346, Meinier GRL15/17), so buyers can choose a seller1
- Lower bottom bracket drop (80 mm) and longer reach (393 mm, size M) improve stability and reduce toe overlap2
Cons
- Early forks had rough grinding, voids and exposed fibres around the brake hose port, some judged unsafe; replacements were not always clean1
- Seatpost wedge bolt loosens after rides even at 7-8 Nm; owners fixed it with a full-length 12.9 bolt, grease on the wedge and Silca Holdfast paste1
- Road cranksets are tight: Shimano 105 rings rub, other road cranks need a 2 mm spacer1
- Paint defects and overspray are common, and gloss paint scuffs easily; seat tube or clamp area can be too tight from overspray or resin and needs sanding1
- Plastic storage door rattles for some riders, seals poorly and leaves narrow, awkward space with hoses inside1
- Headset needs sorting: preload clicks, gaps between spacers and frame, and Lexon or other bar spacers that leave too much or too little room1
- Slow or no replies from SPCycle when problems come up1
- Long 435 mm chainstays and 80 mm BB drop make it calmer and less agile in corners12
- Fork has no fender mounts and supports only 140/160 mm rotors (Meinier version)1
- No build instructions, mismatched thru-axle washers, and wide seat stays that can touch the heel1

Reviews & Ratings
01:06:24The reviewer discusses the Spcycle G028 Gravel frame, highlighting its features such as tire clearance for up to 57mm or MTB tires, a dropped bottom bracket for stability, and a longer reach for better fit. He notes that the frame is made by Tantan, a reputable Chinese manufacturer, and comes with a DH dropout and internal storage. He recommends the frame for its geometry and versatility, though he mentions the chainstay length is a bit long but acceptable.
The SPCycle G028 is a carbon gravel frameset with clearance for 700x57C / 29x2.25 in tyres, T47 85.5 mm, UDH, flat mount brakes, full internal routing, a 27.2 mm seatpost and a downtube storage hatch, ISO 4210 tested. The same frame is sold as Mondince FM346 and Meinier GRL15/GRL17, with the Mondince FM376 close in geometry. It costs about $638 from SPCycle's site including shipping, tariffs and metallic paint (about EUR 500 with cockpit), and weighs about 1000-1050 g claimed, 1200-1271 g measured painted, with a 460-502 g fork; builds land around 8.5-8.75 kg. Owners measure 55-57 mm tyres with 5-8 mm clearance, also with GRX 2x, and describe the ride as smooth, solid and fast, with slower cornering than racier gravel bikes. Early batches had alarming forks (rough grinding, voids and exposed fibres around the brake hose port), and SPCycle replaced some; frames delivered from September 2026 are reported clean, with faced BB and brake mounts. Recurring issues are a seatpost wedge bolt that keeps loosening (solved by a full-length 12.9 bolt, grease on the wedge and strong carbon paste), a seatpost clamp blocked by overspray, headset spacers and compression rings that need sorting, a plastic storage door that rattles for some and leaves awkward space, and slow replies from SPCycle. Road cranksets need spacers because of the frame's width.
