Features

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.

Shock-absorbing fork allows the front wheel to travel up and down over bumps while the handlebars stay steady, for a comfortable, controlled ride.

Accommodates 700x45c tyres with mudguards, or a 29"x2.1" MTB tyre without mudguards.

Built-in mounts make it easy to add racks and mudguards for added versatility.

We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.

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.

Sizing

How tall are you?

To measure your height, stand up straight, barefoot, with your back, heels, shoulders and head all touching a wall. While looking straight ahead, place a book or straight edge on your head and slowly push it against the wall. Your straight edge should be parallel with the floor. Mark the spot where the bottom of the book is touching the wall. The distance from the marked spot to the floor is your height.

What is your inside leg?

How to measure: Stand barefoot with your back straight and against a wall. Tuck a ruler or something that extends to the floor between your legs. Using both hands, and keeping it level, pull the ruler up into your crotch as if you were sitting on the saddle. Measure the distance from the top edge of the ruler to the ground to find your inside leg measurement. Your inside leg is very important to your final bike size so please measure carefully.
