How to Convert a Ten-Speed to a Single Speed

Many bikes use different speeds or gears to adjust speed and adapt the level of effort needed on different terrain. However, having the extra equipment needed to make up a 10-speed bike will add extra weight to the bike. Friction is also higher on a multi-speed bike. Converting a bike to a single speed will simply require more effort from the rider, but for some people this is a preferred option. Converting a 10-speed to a single speed bike is something that almost any bike owner with some knowledge in working with gears can do. You will need to know the parts and terminology of a 10-speed bike, along with removal and installation of these parts.

Instructions

    • 1

      Ride your bike while shifting gears to determine which gear you would like to make the single gear.

    • 2

      Remove portions of the bike that are connected to the multi-gear system. This includes the rear derailleur, brake levers, shift levers, rear cassette, front derailleur and gear housing. Loosen and remove any screws by turning them counter-clockwise with a screwdriver. Loosen and remove and bolts by turning them counter-clockwise with an adjustable wrench. Pull the parts away from the bike with your hand.

    • 3

      Connect the tensioner to the derailleur hanger on the bike. Stand at the back and then the front of the bike to determine whether the tensioner should be mounted on the inside or outside of the derailleur hanger. The preferred side will line up better with one of the chainrings. Mount the tensioner to the derailleur by inserting and tightening the bolts through the holes of both pieces and turning them clockwise with an adjustable wrench.

    • 4

      Detach the inner and outer chainrings from the bike. Loosen and remove the connecting bolts by turning them counter-clockwise with an adjustable wrench.

    • 5

      Install the smaller chainrings in the place from which the old chainrings were removed. Insert and tighten the connecting bolts by turning them clockwise with an adjustable wrench.

    • 6

      Slide the spacers and a cog on the freehub of the rear wheel. Together, they should align with the chainring and the tensioner.

    • 7

      Wrap the new chain around the tensioner and the cog of the bike. You will want to use the shortest chain possible that will wrap around these pieces.

    • 8

      Push up the tensioner with your hand to adjust it and remove any slack from the chain.

    • 9

      Check for tight spots or friction on the chain by turning the cranks of the bike with your hand. If you notice any glitches while turning the cranks, these are tight areas of the chain. Turn the small connectors in the tight locations of the chain counter-clockwise with a chain tool to loosen them.
