Will my bike have a curved top tube?
Size Small frames have a top tube that dips down as it approaches the seat tube. This makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders typically don't have the same issues.
DuoTrap S compatible
DuoTrap S (sold separately) integrates a Bluetooth®/ANT+ sensor into the frame. Log routes and track fitness progress on your computer or smart phone with no external sensor. Works with all major ANT+ wireless players, including Bontrager, Garmin, PowerTap, and SRM.
Massive tyre clearance
Accommodates 700x45c tyres with mudguards, or a 29"x2.1" MTB tyre without mudguards.
Rack & mudguard ready
Built-in mounts make it easy to add racks and mudguards for added versatility.
Handlebar-mounted controls for on-the-fly suspension lockout as you switch terrains.
Shock-absorbing fork allows the front wheel to travel up and down over bumps while the handlebars stay steady, for a comfortable, controlled ride.
