Hi everyone,

I’m planning a new lightweight race bike build and would appreciate feedback specifically on the fit.

I’m 188 cm tall and looking at the Quick Pro AR:One in Size XXL / 58 cm frame. My current bike (Canyon Endurace in Size L - which is also 58cm) has a more endurance-oriented fit, which I like, but I would build this new bike as a race bike with a more aggressive position.

My current bike was fitted to me by a professional bike fitter, and I am happy with the fit. So I calculated my new position on the new bike, while leavin the two contact points: saddle to bb relative to each other in the same position as they currently are. So only my reach changes, but quite significantly I would say.

Compared with my current bike, the new setup would be roughly:

• 80 mm longer in reach with a 100 mm stem
• 40 mm lower in stack / bar height
• While using around 30 mm of spacers
• Considering a stem between 80 mm and 100 mm, and spacers between 30 mm to 50 mm

My concern is whether this jump from my current endurance setup to the new race setup is reasonable, or whether it sounds too aggressive.

Would an 80 mm stem make more sense as a starting point, or is the 100 mm stem likely appropriate for someone my height on this frame size? I heard that if I go shorter, then I might be too cramped because I need to rech further down due to the lower stack...

Does 30 to 50 mm of spacers sound acceptable or is that too high? Not concerned about looks, but more about stability. I read somewhere that 30mm spacers is the maximum that should be applied because of stability reasons?

I know a proper fit depends on flexibility, proportions, riding style, and current position, but I’d appreciate any general thoughts on whether this sounds like a sensible race fit progression or a red flag.

Hi everyone,

I’m planning a lightweight road bike build and would appreciate some feedback on compatibility, part choices, and whether the fit looks too aggressive.

I’m 188 cm tall and planning to go with the XXL / 58 cm frame size. My current bike is more of an endurance setup, while this will be my race bike. The new setup would be roughly 80 mm longer in reach (with 100mm stem) and 40 mm lower in stack/drop than my current bike. I’m considering either an 80 mm or 100 mm stem, likely with around 30 mm of spacers. Does that sound reasonable, or too aggressive?

Estimated total weight: ~6.64 kg

Estimated total cost: ~5,913 €

Planned build:

• Frame: QuickPro AR XXL frameset, with 0 mm offset seatpost
• Cockpit: Zephyr-SSL integrated aero cockpit, 38 cm wide, 80–100 mm stem
• Bottom bracket: SRAM DUB BSA 68/73
• Crankset: OVERFAST carbon crankset, 170 mm, spider power meter
• 52/36 Cybrei Carbon Chanrings
• Front/Rear Derailleur : SRAM Force AXS 2x12
• Cassette: Neutron Lightweight MK2 12-speed, 11–34T, Shimano HG freehub
• Chain: Shimano XTR CN-M9100 12-speed
• Wheels: Particle GCX Hyperlight, 45 mm deep, 25 mm internal / 32 mm external
• Brakes: SRAM Force hydraulic disc
• Rotors: KACTUS ultralight, 160 mm front / 140 mm rear
• Tires: Continental GP 5000, 28 mm

My main questions are:

1. Does everything look technically compatible?
2. Is the SRAM Force AXS setup likely to work well with the Neutron 11–34 cassette and Shimano XTR 12-speed chain?
3. Is the SRAM DUB / BSA bottom bracket setup correct for this frame and crank?
4. Are the wheels a good modern setup for 28–30 mm tires?
5. Should I consider deeper/shallower rims? I think 45mm is the allrounder - not too heavy but still aero.
6. Do any of the ultralight parts look risky from a reliability or safety perspective?
7. Based on my height and the planned XXL/58 cm frame, does the fit sound reasonable, or am I going too aggressive?

I’m aiming for a lightweight road bike, but I still want it to be practical and reliable rather than a fragile weight-weenie build. Any feedback or suggestions would be appreciated.
