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, 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 axel, 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, 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 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 taunt.
- 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.
