Shimano Sora is a combination brake lever/shift lever system made for entry-level road bikes. Using a single lever for braking and upshifting, Sora shifters make riding a bicycle intuitive and fun. The system is affordable, works well, and is relatively easy to install, making it ideal for converting bikes to the new STI shift/brake system. Learn how to install your Sora shifters at home and save time and money over having them installed at your local bike shop.

Instructions

  1. 1

    Set your bike on its kickstand or in a dedicated bicycle work stand. If you don't have either of these available, remove the front wheel and set the fork on the ground, so the bike will stay upright while you work. Be careful not to knock it over.

  2. 2

    Remove the bar tape on both sides of the handlebars and the bar end plugs that hold it in place. Set the tape and plugs aside as you will be reinstalling them later.

  3. 3

    Slide a 5mm hex wrench between the plastic body and rubber grip on the left shifter. The wrench should interface with the shifter clamp bolt on the inside of the shifter. Loosen this bolt to open the shifter clamp, then slide the shifter onto the left side of the handlebar. Tighten the clamp bolt to hold the shifter in place. Install the right shifter on the right side of the handlebar in the same fashion.

  4. 4

    Slide the longest piece of right brake housing onto the brake cable that exits the rear of the right shifter. Attach the end of this housing to the rear brake cable braze-on on the toptube of the frame, and secure the housing to the housing guide on the front of the handlebar using electrical tape. Route the cable to the rear braze-on, near the seat tube. Slide the small piece of housing onto the cable and attach it to the rear braze-on and the rear brake. Close the rear brake by hand and tighten the cable in the rear brake cable stop using a 5mm hex wrench.

  5. 5

    Slide the left brake cable through the left brake cable housing and secure the housing to the bars using electrical tape. Insert the end of the cable and housing into the front brake cable housing stop. Close the brake by hand and tighten the cable in the cable stop using a 5mm hex wrench to secure it.

  6. 6

    Slide the cable exiting the front of the left shifter through the left shift cable housing. Attach the housing to the housing stop on the left side of the down tube of the bike and run the cable through the cable guide under the bottom bracket. Slide the cable through the front derailleur cable stop and tighten the cable stop using a 5mm hex wrench.

  7. 7

    Slide the cable exiting the front of the right shifter through the right shift cable housing. Attach the end of this housing to to the housing stop on the down tube of the bicycle frame and run the cable through the rear derailleur cable guide under the bottom bracket. Use the small piece of rear derailleur housing to connect the cable to the rear derailleur braze-on and the rear derailleur cable stop. Tighten the cable stop using a 5mm hex wrench to hold the cable in place.

  8. 8

    Fold the rubber grip over the plastic body of both shifters. Rewrap the handlebars using the handlebar tape removed earlier, starting at the end of the handlebar. Be sure to wrap the tape clockwise on the right handlebar, and counterclockwise on the left. This will keep the tape from unravelling as you ride. Secure the tape to the bars using electrical tape.

  9. 9

    Take the bike out for a test ride. To brake, pull the silver lever of both shifters toward the bars. To shift to an easier gear, press the silver lever of the right shifter in toward the left, or press down on the thumb lever of the left shifter. To shift to a harder gear, press the thumb lever of the right shifter, or press the silver lever of the left shifter toward the right.
