Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2006 Trek T 900 and 2007 Trek T 900.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM = pedal turns per minute.
Uses front tire 26×1.95; rear size isn’t listed.
Uses front tire 26×1.95; rear size isn’t listed.
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.
Historical specifications are presented as an archival reference. Components may have varied by market, size, or production run.
