Handlebars

Handlebars

• Like stems, handlebars come in various styles, lengths and diameters
• Some common handlebar diameters are 22.2, 25.4, 26.0, 31.8, and 35mm
• An example of just a few different styles:

 

• If your handlebar is not stamped with its diameter, the use a caliper will help
• If you don’t have the handlebars and the stem also has no markings,
• It is difficult to determine the clamp diameter of the stem by measuring it again with a calipers be as accurate as you can.
• But the clamp diameter is typically engraved or labeled on the stem
• Incompatible components can be a safety hazard, so always double-check with the manufacturer for specifications and compatibility information

 

• Apply grease or thread locker to the face plate bolts.
• Place the face plate over the front of the bars and thread in the bolts, but do not tighten them fully.
• These bolts should be tightened evenly and the gap between the stem and the face plate should typically be even on the top and bottom. This reduces stress on the bolt heads.

 

• Threaded stems often use a compression style fitting, with a single bolt at the top or bottom holding the bar to the stem. To remove the bars, loosen the bolt securing the bar to the stem. Then simply slide the bar out.

 

• With the handlebars now loosely fitted, set the bike on the ground, stand over the bike and make sure the bar is centered in the stem. Then set the bars to the desired amount of roll.

• Torque the bolt/bolts to the recommended figure given by the manufacture
• You can then install the brake/gear levers, bell, grips as required
