Mar 1, - Mountain bike geometry explained in 9 numbers Modern bikes favour steeper angles that put the saddle directly over the bottom bracket.

More trail is nice at high speeds motorcycles usually have 80 mm bike frame geometry explained trail but can feel sluggish fra,e slower speeds. A steep head angle is more upright and takes less effort to turn the front wheel, especially if there is too much rake or too little trail.

How does frame geometry affect a bike?

A shallow head angle will want to turn too quickly when leaned if there is too little trail or not enough offset. So most shallow angle bikes have plenty of fork offset to compensate.

Head tube angles range from The actual top tube length is measured from the top and head tube junction to the top and seat tube junction. The effective top tube is measured horizontally bike frame geometry explained the junction of the head and top tube to the seat tube.

Due to most bikes having a sloping top tube, usually for added clearance, the effective top tube is a better measure of length when comparing different bike frame geometry explained. The idea is to position the rider for optimized pedaling, or to target specific muscle biker bracelets in order to use them more. A rider can artificially change the seat tube angle by moving the saddle forward or back on the rails.

This is up to the rider though and can also be determined by riding style or when the bike is fit after a purchase. A short bike stuff length improves handling but can sacrifice stability.

Chain Bike frame geometry explained Length Chain stay length is measured from center of the bottom bracket to the center of the rear axle. This length is determined geeometry wheel size and bike style.

Longer chain stays provide more stability but can hamper handling on technical trails. Most bikes these days feature quite short chainstays around a larger bike frame geometry explained For easy reference, the Santa Cruz Bronson pictured has a relatively short chain stay at That said, there are rear racks that push your panniers further back if you need.

Touring bike mm Road bikes mm CX mm. A longer wheelbase provides bike frame geometry explained more stable and comfortable ride. Touring bikes have a long wheelbase due to a combination of a slack head angle, long fork rake and long chainstay length. Touring bikes mm Road bikes mm CX mm.

Bottom bracket drop determines how high your bike frame geometry explained sit from the ground when you pedal. A lower bottom bracket results in a lower saddle height and therefore a lower centre of gravity. Touring bikes may need pedal clearance over obstacles, so some manufacturers provide a high bottom bracket 53mm drop with c wheels.

This is generally offered on off-road touring bikes. Other manufacturers provide a low bottom bracket 78mm drop with c wheels bike frame geometry explained maximise the stability of the bike, albeit at the risk of pedal strike at times.

Geometry of Bike Handling

This is more common with the road-oriented touring bikes. The measurement comes simply from the distance between the centres of both wheels.

It can be represented in two parts: Exllained bikes and adventure bikes then will have longer wheelbases, with endurance bikes in the middle and race bikes at the bike frame geometry explained end of the scale.

As an example, a size 54 Specialized Roubaix has a wheelbase of mm vs for a Venge. Of course, the wheelbase of an all round smaller bike will be shorter, bike frame geometry explained a rider who framr a really agile bike might choose a smaller bike, using a longer stem and handlebars to get the reach they want.

Another element that will influence stability is bike frame geometry explained bracket drop — how far the BB drops down from the two wheel axles. This gometry has changed over time, with factors such as larger tyres playing a role.
