Key differences

Supported differences are shown below. Data limitations are labeled separately.

  1. Data limitation

    No geometry is recorded for 2007 Surly Steamroller and 2012 Surly Steamroller.

  2. Gearing

    2012 Surly Steamroller has a 18% lower climbing ratio than 2007 Surly Steamroller.

    A lower ratio gives more mechanical advantage; rear-wheel rollout determines distance per crank turn.

  3. Identity & price

    2007 Surly Steamroller had an original MSRP $120 lower than 2012 Surly Steamroller.

    Original MSRP is the published list price when new, not today’s used-bike value.

Gearing comparison

Lower gears help on climbs. Higher gears suit higher speeds.

RPM

RPM = pedal turns per minute.

2007 Surly Steamroller48T · 17T · 1-speed
Ratio2.82:1
Estimated speed at 90 RPMGear20.0 mph

Uses front tire 700C×25; rear size isn’t listed.

2012 Surly Steamroller44T · 19T
Ratio2.32:1

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.
