Road Bike Gear Trimming
For the basics on how to change up and down the gears we explained shifting on shimano sram and campagnolo gear systems here.
Road bike gear trimming. Everyone climbs in their own way some people like to stick to lower gears and spin their legs as much as possible whilst. Last edited by 514climber. Either way trimming is an important skill to have when you access the gears in the extremes of your bike s range. The two gear shifters of the shimano 105 each control a derailleur which changes gears by moving the chain from one sprocket to the next.
Feed the exposed end of the gear cable through the mount closest to the front of your bike and pull it tight so the outer cable presses against the mount. With more road bikes now being fitted with hydraulic disc brakes sooner or later you re going to need to trim one to length or understand how to disconnect and reconnect one if you re also using internally routed hoses and cables. It s really no more complicated than looking after traditional wire cable brakes. Look for the 2 3 mounts which look like small black cylinders on the bottom horizontal tube of your bike.

Set up and adjust your rear derailleur duration. The trim function is essentially a microshift or half shift it moves the front mech ever so slightly without moving the chain off the chainring like a full or regular shift. Gcn tech 88 068 views. This most likely means there will be chain rub when actually riding in this gear.
Run the gear cable through the mounts on your bike frame. Trek is the 1 performance bike brand in the world. There is one derailleur at the front and one at the rear. I just put my bike on the stand and there is smallest possible gap when i m in 55x27.
