How to Remove and Replace the Bottom Bracket on an Indoor Cycling Bike


Following is a basic guideline of removing and replacing the bottom bracket on an indoor cycling bike. Due to the different brands of indoor cycling bikes and designs for bottom brackets, the following should only be used as a guideline. If any of the information is not exact to the bike being serviced, refer to the service manual or call Sportsmith for further help.
Common Tools Needed:
Phillips Screw Driver
Set of Allen Wrenches (standard and metric)
Bottom Bracket Tool
Cotterless Crank Puller Tool
9/16" Socket
Ratchet Wrench
Pedal Wrench
Crescent Wrench
You will begin by removing the outside belt/chain guard by using either or both the Phillips screw driver and Allen wrenches. It may be necessary to remove the drive side pedal (using the pedal wrench) in order to completely remove the outside belt/chain guard.
Once the belt/chain guard is removed, you will need to remove the belt/chain. If the unit is belt driven, you can simply "walk" the belt off the pulley by pushing the belt to the outside while turning the crank backwards. **CAUTION: PINCH POINT ** If the unit is chain driven, most use a continuous chain that can be "walked" off the sprocket just like the belt. **CAUTION: PINCH POINT ** Some chains may use a connecting link and can be separated at the connecting link to remove the chain. The connecting link is different in appearance from all other chain links.
Now it is time to remove the crank arms. How to Use a Cotterless Crank Puller Tool
It works best to place the bike upside down for best leverage to remove the bottom bracket. (If placing the bike upside down, ensure proper seat adjustment for best bike balance.) Begin removing the bottom bracket from the drive side of the bike. This side has a reverse thread. You will need to turn right to loosen and remove the bottom bracket. Place the teeth of the bottom bracket tool into the teeth of the bottom bracket cup. Using the ratchet wrench or crescent wrench to turn the bottom bracket tool, you will turn right to loosen and remove the bottom bracket. (If removal of the bottom bracket is difficult, it helps to use a crescent wrench in combination with a bolt threaded into the bottom bracket shaft to hold the tool in place while applying pressure to break the bottom bracket loose.) Remove the bottom bracket from the frame. Remove the bottom bracket cup and/or lock ring from the non-drive side of the bike. This is a standard thread. You will turn left to loosen and remove this bottom bracket cup and/or lock ring.
Install the new bottom bracket from the drive side and tighten flush to the frame. Install the bottom bracket cup and/or lock ring to the non-drive side and tighten.
Re-install the crank arms and pedals. Make sure the crank arm bolts are tightened to the proper torque. If unsure of proper torque specs, refer to the equipment service manual or call Sportsmith.
Re-install the belt/chain onto the pulley/sprocket. If belt/chain was "walked" off the pulley for removal, it can be "walked" onto the pulley/sprocket by placing the belt or chain along the bottom of the pulley/sprocket. Carefully, turn the crank arm forward while lifting on the belt/chain. **CAUTION: PINCH POINT ** Continuing turning the crank forward until the belt/chain is in place.
Re-install the outside chain guard and test the unit. Ride the bike without tension and test with tension. Ensure functionality and feel of the ride. Make any adjustments if necessary

Bottom Bracket & Spindle Replacement of LeMond RevMaster


Part 1 Video Discussing the Dis-assembly & Inspection of the Bottom Bracket & Spindle for a LeMond RevMaster Bike

  • This Part 1 video will demonstrate how to inspect and adjust or remove and replace the bottom bracket and spindle on your Lemond Revmaster
  • Tools needed for this procedure:
    • 8mm Allen Wrench or Socket
    • Cotterless Crank Puller Tool
    • Lock Ring Removal Tool
    • Bottom Bracket Tool
    • Phillips Screwdriver
    • 4mm Allen Wrench
    • Bungee (optional)
    • Rubber Mallet
    • 7/8" Wrench
  • To begin remove the belt cover, there are four screws
    • You will need a 4MM Allen wrench
  • Now remove the two screws on the back from the opposite side of the bike
    • You will need a Phillips screwdriver
  • Now position the crank arm as seen in the video and remove the belt cover from the bike
  • Before removing the drive belt, tighten the brake assembly so that the flywheel is locked in place and loosen the torque on both bolts using an 8mm Allen wrench or socket
    • Do not remove them at this time only loosen them by a half a turn or so
  • Using a 7/8" wrench loosen the belt idler
  • Now use a 4mm Allen wrench to loosen the tension adjustment bolt completely, but do not remove it from the frame
  • Now remove the drive belt
    • To aid in this process you can use a bungee to slide in behind the belt at the top, as shown in the video
  • Then pull away from the bike while spinning the crank arms
  • Now remove both crank bolts with a 8MM Allen wrench or socket
    • Removal of the crank bolt on the left side of the bike is the same as removal from the right side
  • Now remove the crank arms with a crank arm puller, threading the outer portion into the crank arm as shown in the video
    • Be sure to thread the outer portion in as far as possible to prevent damage to the crank arm threads or the tools threads
    • Use a 7/8" wrench to make sure the outer portion is threaded in completely
    • Now spin the handle clockwise to press the crank arm off of the bike
    • Be careful when the crank arm comes off as if you are not holding it, it can fall in the floor
    • Also use the wrench to loosen the tool before removing the crank arm from the unit
    • Now you can unthread the tool from the cranks arm by hand after removing the crank arm from the bike
  • Next inspect the bottom bracket cups for looseness, to do this use the bottom bracket tool by hand to see if you can turn either of the bearing cups
    • To further verify the adjustment of your bottom bracket use a rubber mallet to tap lightly on each side of the spindle to check for movement from side to side, if you have movement, or one or both of the bearing cups is loose, you need to re-adjust the bottom bracket. If you are only inspecting the bottom bracket and did not find any need for adjustment you would re-assemble the bike at this point
  • Once the crank arms are removed look closely at the spindle
    • It should have defined edges and be smooth
  • As you can see by the video our spindle needs to be replaced
  • Next you will need to remove the lock ring
    • The lock ring is around the bottom bracket cup on the left side of the bike
      • In the video is an example of a lock ring
    • To use the lock ring tool you slip it over the lock ring using the three notches and torque the lock ring in the proper direction
      • This one needs to be turned counter-clockwise to loosen
    • Then remove the lock ring by spinning it off the bearing cup
  • Next you will need to use the bottom bracket tool to remove the bottom bracket cups
    • Begin with the left side
      • Slip the tool into the splines of the cup and loosen
        • For stubborn bottom brackets use a 5/16"-24 x 2" bolt and some washers with a 1-1/4" wrench
          • Slip the tool into the splines and thread the bolt with the washers into the spindle
          • Get it snug but not completely tight
      • Now use the wrench to turn the cup counter-clockwise for the left side and remove it completely
    • Remove the cup from the right side now
      • Slip the bottom bracket tool into the splines of the cup and turn it clockwise to loosen
        • For stubborn bottom brackets use a 5/16"-24 x 2" bolt and some washers with a 1-1/4" wrench
          • Slip the tool into the splines and thread the bolt with the washers into the spindle
    • If you cannot get the cups loose with this method try turning the bike on its side to get better leverage as shown in the video
  • This concludes the dis-assembly and inspection procedure of the LeMond RevMaster bottom bracket & spindle
  • Click here to see Part 2, re-assembly and installation to complete the replacement procedure

Getting a clicking sound from the bottom bracket area. I have a Denali Pro. Can I replace the bottom bracket and what size


Yes, of course you can replace the bottom bracket.

First though you will want to make sure that the clicking noise is in-fact coming from the bottom bracket. Even though it sounds like it is coming from that area there are other things that can cause a clicking noise, such as the examples below.

Front derailleur cable end hitting the crank-arm is a common clicking noise.
Pedals can also cause a clicking noise that sounds like its the bottom bracket.
chain rubbing the front derailleur
chain has a kink in it.

The size of your bottom bracket is related to a few factors:
1 - thread pitch (your bike is english)
2 - Bottom bracket width (your bike is 68)
3 - Crank style and brand. This I do not know for your particular bike as you did not provide the year of the bicycle or brand of crank, and they change.

Taking off cranks and removing and installing a bottom bracket requires many bike specialty tools and is probably not the best project if you have never done this before or own the tools. It will be far less expensive to have your local bike shop replace the Bottom Bracket then to do it yourself. Plus they can tell you what size it needs and if the click is even coming from that part or not.

Got a 1999 Diamondback Wildwood bike and was trying to take off the crankshaft and front sproket. Do I need a special tool for that? What's the trick?


Hi, yes you do need a special tool. It's called a Crank Arm Remover. The tool is basically a modified puller that threads first into the inside of the crank, (after the bottom bracket bolt is removed) where it is bolted to the bottom bracket. Then, a second bolt is then threaded inward against the tapered shaft of the bottom bracket. Slowly the crank will lift away from the tapered shaft of the bottom bracket. Hope this helps.

Have a old american flyer road bike and want to change bottom bracket. not sure what size


Go to a bike shop and let them measure your cranks. Do you have a one piece or three piece crank? Do you have metric wrenches? Bottom bracket tool? You have to know the answers to these things to get the right size bearings, if it is a one piece you more than likely have a #66 but without seeing it, who knows.

Are ALL Colnago bottom brackets 'Italian' thread? Or do they also offer English, too? Thanks


Yes, everything is metric on all bikes, our country does not make bike parts anymore. Get a good set from a top bike shop, bottom bracket tools etc because you need quality tools not junk. It is well worth the investment if you know what you are doing, always remember it is far cheaper to take it in for repair than crossthreading something, then it is big bucks to fix.

Hi trying to re grease the pedal sprocket bearings on my Ross Rock Machine mountain bike. I got off the pedal arm on the right side but can't figure out how the left side comes off. The pedal arm looks...


Bottom brackets are sealed, removing the seal will have potential for damage. If it's making noise, replace it or better yet upgrade as a crankset. You'll have new crankarms, bottom bracket, chainrings with it. Unless you have the correct bicycle tools (not general automotive tools) you won't be able to pull your crank and even reach the seal for the bottom bracket.

I have a Schwinn Avenue hybrid bike that has a clunking sound in the crank area. Is this normal? I'm wondering if there is some maintenance that I need to do on this bike. Bike was purchased new in May and...


No, not natural. If it only does it when the front derailleur is in the big chain ring, then check to see if the crank is hitting the front derailleur. If that is not it, then the crank arms might need tightening. If not that, then the problem might be in the bottom bracket.
