The 10-Speed kit will come with a new chain entirely that will need to be sized.
- Remove drive side (right) pedal.
- Use a 15mm Open Wrench to remove the drive side (right) pedal, twist the wrench counter-clockwise to loosen, and remove the pedal from the right crank.
- Using the same 15mm wrench, remove the non-drive (left) side pedal. Twist pedal clockwise as this is a reverse threaded part.
- Remove chain
- A chain breaker loosens one link in the bike's chain, allowing the chain to come off the bike entirely.
- Remove both cranks and chainring.
- Use an 8mm hex key to remove the crank screw out of each crank (counter-clockwise)
- Once the crank screw is completely removed, use a crank puller to separate each crank from the bottom bracket.
- Remove rear wheel
- For directions on removing the rear wheel, please see the article here.
- Remove the right grip, brake lever, and throttle from handlebars
- With a 2mm hex key, loosen and remove both grip ends on the handlebar. The grip will slide off the handlebar after bar ends are loosened.
- With a 4 mm hex key, loosen the brake lever to slide off handlebars.
- With a 3mm hex key, loosen and remove the throttle from handlebars.
- Install brake levers, shifter, throttle, and grip on handlebars
- When installing a handlebar shifter, ensure that the cable stays clean by coiling up the wire.
- Place the shifter on the bars against the throttle with the low gear lever on top and with the high gear lever on the bottom.
- Ensure that the low gear shifter is at the highest gear, maximizing the shifting cable's length. Click the smaller of the 2 paddles to release any remaining shifts.
- Install 10-speed cogs onto the wheel
- With the rear wheel removed from the bike, install the 10 cogs onto the axle.
- Remove the drive-side drop-out nuts with the 18mm open wrench and torque wrench and any washers. Please pay attention to their orientation for when they go back on after installing the cogs.
- Remove the original cog on the bike. To do this, use a chain whip to hold the cog in place, and insert a cassette removal tool with a wrench to loosen the axle nut. Twist each side opposite each other to loosen, turning the right axle nut counter-clockwise.
- Once the cog is removed, position the 10-speed cogs on the cassette spindle. On the spindle, there are grooves throughout, with one slightly wider than the rest. Locate the wide grove to line up with the 10-speed bundle for installing. When positioned correctly, the 10-speed will effortlessly slide onto the cassette spindle.
- After placing the cogs on the axle, tighten the axle nut on top with a cassette tool and wrench. *While tightening, it is normal to hear a clicking sound coming from the bolt.
- With the 10speed installed, add the round, thick washer, and the drop-out cassette, followed by the thin washer and 18mm nut.
- Install rear wheel back onto the frame
- Please see the article here for directions on installing the wheel onto the frame.
- Install derailleur
- Properly route shifter cables through the bike's frame, ending at the rider's side right. The cable will route underneath the bottom bracket and out to where the derailleur will hang.
- Remove the bike's chain tensioner by unscrewing it from the hanger. The new derailleur will fit and thread into the hanger. Use a 5mm hex key to tighten.
- Run shifter cable through cable line and bike frame Article here
- Route cable to the rear-drive side of the frame. The cable will connect to the derailleur. File down the cable line to expose the shifter cable.
- Install shifter cable onto the derailleur
Pull the cable tight and attach to the derailleur. Tighten with a 5mm hex key. To tighten the cable, shift the lever several times to change into a bigger sprocket or chainring. This will settle the cable into place and apply tension on it; the cable must be taut.
- Install new cranks and chainring
- You will install the new chainring on the right crank arm. With a flathead, fasten the four mounting screws onto the crank. Once secure, the cranks are ready to be installed onto the bike. (this should come installed already)
- Ensure that the cranks are in an opposite position of each other before tightening. i.e., each in a 12 o'clock and 6 o'clock position. Once in position, install and tighten each crank screw with an 8mm hex key.
- When each crank is in the correct position, tighten and install the pedals.
- Use a 15mm Open Wrench to tighten the right pedal. Twist the wrench clockwise to tighten the pedal onto the right crank.
- Using the same 15mm wrench, twist the left pedal counter-clockwise to tighten.
- Reattach new chain and cut to size
- Run the chain over the smallest cog in the 10-speed cassette, bypassing the derailleur and around the chainring.
- Turn the cranks to guide and fit the chain smoothly over the chain wheel and through the derailleur.
- Once the chain is successfully installed, turn the cranks and shift through each gear to ensure each cog works as designed.
