Gravity FSX 29 inch Aluminum Dual Suspension Mountain Bike ATB Bike Frame Set Fork Headset Seatpost

Good

So I bought the silver frame of this model from a listing that has now been removed by the same seller, Sun Cycle Warehouse

The frame did not come as listed. The swing-arm was black with “Shimano Equipped” painted on the chainstays rather than the fully silver I expected so -1 star. To my surprise it came with a headset, stem, and cheap heavy fork sooo +1 star?

The rear spring shock preload adjuster is also very difficult to turn. I lubricated the threads and tried tightening by hand and only got about halfway tight on the threads. I tried taking the shock off and tightening with a Shimano Hollowtech BB tool that looked like it should have fit but didn’t. TBH I didnt care enough since I’m replacing the spring shock with an air one soon anyway but still -1 star.

The main issue I ran into was the rear IS brake mount was not at all to spec. The mount was about 4mm-ish too far inboard causing the brakes to rub the rotor pretty badly. I tried 2 different brake calipers; a Promax DSK300 and an Avid BB7M. Same issue. I tried 2 different rear wheels with an Origin8 MT2100 hub and a Wheelmaster MT-2000 hub. Same issue. I tried 2 different brake rotors; a Shimano XT and some no name rotor off a Poseidon bike. Same issue. I used an old IS to 160mm PM brake mount from a Trek hardtail that was working fine. Same issue. I bought a new Shimano ‎ISMMAR160PSA and it actually got worse lol.

I even took apart the Wheelmaster rear axle and made sure the bearing crowns were well adjusted and the axle spacing was to spec. Real PIA.

So after aaallll that I’m 1000% confident its bad QC on the rear brake mounts. So I took a Dremel to it and ground them back a couple millimeters and now they brakes work great. Overall not a great experience but the frame was very affordable. -1 star.

So if my math is right that’s 3 stars?
