Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2002 Burley HepCat and 2004 Burley Hepcat.
- Gearing
2002 Burley HepCat has a 6% lower climbing ratio than 2004 Burley Hepcat.
A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.
Lowest0.88:1Highest4.73:1Total range536%
Speed unavailable: wheel or tire size is missing or unclear.
Lowest0.94:1Highest4.82:1Total range514%
Speed unavailable: wheel or tire size is missing or unclear.
How it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
