Velopedia analysis
What the specifications mean
On the steel frame, paint damage and moisture entry deserve attention because corrosion can begin at scratches, vent holes or internal surfaces. A threaded bottom bracket still requires the correct shell width, thread standard and crank-spindle interface before replacement. The published Size 485 unpainted frame: 1.895g weight is a reference for the documented build; frame size, pedals, tire setup and production substitutions can change an actual scale reading.

Used-frameset inspection
If you’re buying this frameset used
Before buying: confirm the serial number and exact model, inspect frame and fork alignment, and inventory every included axle, hanger, clamp, headset part, cable guide and proprietary fitting.
Inspect the frame and fork →- FrameCheck paint chips, vent holes and the inside of the seat tube for corrosion. Also look for dents, bent tubes and cracking around welded or brazed joints.Inspect the frame and fork →
- Bottom bracket shellInspect the bottom-bracket shell for damaged threads, corrosion, ovalization, cracks or signs of an improvised repair. Confirm the archived shell standard and width before buying components.Inspect the bottom bracket and shell →
- Included hardwareInventory every axle, hanger, clamp, headset part, cable guide, frame plug and proprietary fitting included with the frameset. Confirm replacement availability before treating a missing small part as insignificant.

Geometry interpretation
What this geometry means
420 geometry
Riding position
The 512 mm stack is low relative to the 370 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 75.5° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 70.8° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 74 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The head angle of 70.8° sits toward the steeper end. The seat angle of 75.5° sits somewhat steeper than typical. Its stack of 512 mm sits somewhat taller than typical.
455 geometry
Riding position
The 525 mm stack is low relative to the 375 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 75.3° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 71.6° head angle points to more stability-oriented steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 74 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The seat angle of 75.3° sits toward the steeper end. The head angle of 71.6° sits toward the steeper end. Its stack of 525 mm sits somewhat taller than typical.
485 geometry
Riding position
The 543 mm stack is low relative to the 382 mm reach, giving the frame a performance-oriented, lower-front-end proportion with more potential for a stretched riding position. A 74.8° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 72.5° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.
Archive context
The head angle of 72.5° sits toward the steeper end. The seat angle of 74.8° sits toward the steeper end. Its stack of 543 mm sits toward the taller end.
510 geometry
Riding position
The 387 mm reach and 562 mm stack form a moderate road-bike proportion, balancing cockpit length with front-end height rather than pushing to an extreme race-low or endurance-upright shape. A 74.5° seat angle puts the rider relatively forward over the bottom bracket, shortening the effective seated reach compared with a more relaxed seat angle.
Handling tendencies
The 72.9° head angle points to moderate and balanced steering geometry. Head angle is only one part of steering feel; fork offset, trail, wheel size and cockpit setup also matter. A 72 mm bottom-bracket drop places the rider relatively low between the wheels, which can add a settled cornering feel while reducing pedal clearance compared with a higher bottom bracket.

570 geometry
Riding position

Across the size range
From 420 to 570, reach grows by 39 mm and stack by 107 mm, showing how the frame becomes both longer and taller through the published size range. Chainstay length grows from 410 to 415 mm across the range. That size-specific rear-center strategy helps the larger frames grow at both ends instead of adding all of their length ahead of the bottom bracket.
Geometry describes frame proportions and likely tendencies, not a ride test. Rider proportions, cockpit setup, tires, suspension settings, wheel configuration, and component choices can materially change how a bicycle fits and feels.
