Did you use spacers for the BB area please?

What’s your cassette / chainring size please ? (Mine is 11-34 cassette and 50-34 chainrings, 2x12v, ultegra r8100)

Didnt use any spacers. Running a 11-34/52-36. Could there be a spacer missing in the cassette?

Just pulled the trigger on a GasCycle Nitrogen alloy frame (size S). It's still being built — the seller says it'll ship around the end of the month, so I've got a bit of a wait before the fun starts.

The idea: my actual dream bike is the Cannondale CAAD14, but on a student budget that's not happening, so this is my crit-focused take on it — with a bit of a wink toward the Standert Kreissäge RS as well. I'm coming off a LightCarbon LCR018-D endurance bike, so this is a deliberate move to a lower, racier position.

Use case: flat-ish criterium racing. Aggressive position, running 1x to keep things clean.

Planned build:
- Frame: GasCycle Nitrogen, alloy, size S
- Groupset: SRAM XPLR 1x13 AXS (Rival/Force mix)
- Crank: TBD (likely a powerless SRAM AXS crank + power pedals)
- Chainring: AluGear Aero "Golf Ball" 54T, black
- Chain: SRAM 12s flattop
- Cassette: 10–46
- BB: ZTTO BSA-DUB (open to better suggestions)
- Cockpit: Zipp Service Course SL-80 + Kalloy Uno stem (trying out different lengths and angles)
- Wheels: LightCarbon C67DB carbon
- Tyres: Continental GP5000 (28–32c, still deciding)

Planning a little custom "knock-off lucky cat" head tube sticker too:



Will post build pics once the frame lands. Cheers!
