You have two MTB Bars to choose from: a classic flat center rise bar and a 15mm We've created two carbon fiber bars for the Mountain Bike enthusiast: a flat bar with an tolerance clamp sections, it's the best bar for your Thomson X4 stem.
Most threadless mountain bike stems are measured in millimeters.
Lift your leg over the bike to straddle the frame. Lower yourself onto the seat, and place your feet flat on the floor. Extend your arms toward the handlebars, and bikr hold of the grips.
Examine the curvature of your arms to determine if the stem corresponds with your physical dimensions. Fuber a stem that's 20mm to 30mm smaller if your arms must fully extend to reach the handlebar grips.
Upgrade the size of the stem if your arms bend at less than a degree angle. Which is fair enough.
There are two clamps on a stem. A handlebar clamp at the front and a fork steerer clamp at the back.
Almost all decent stems use a 4-bolt design for the front bar clamp. Strong, stiff and less creak-prone than old fashioned 2-bolt face plate designs.
The rear clamp — where the stem fits on to the fork steerer — sees a tiny bit more variation in design. The vast majority use a 2-bolt design.
Some DH stems use a big single bolt at the back. These can really hurt your knees if you crash.
Most decent stem designs have cowled or rounded-off bolt head designs. As usual, check the sale sections for bargains.
Racers will want to avoid heavy stems but the key quality they should look for in a stem is stiffness. CNC stems should be on your shortlist. Spendy racers may wish to consider carbon.
In the market for some new bars? They're not only an essential for physically holding on to your bike, but also a key aspect of how it feels on the trail and, more importantly, how well it fits you.
