this is the kit

I believe the spacer with the bearing and the new flat sprocket bolt to the wheel hub with the four, longer nuts and bolts.

 

The other spacer replaces the right hand spacer on the wheel spindle/axle, the original one will be too long with the new spacer/bearing bolted to the wheel hub, so a short spindle spacer is needed to get the rear wheel to fit the swinging arm.

 

While it's all apart, check the spindle/axle is straight, they are quite narrow for a trials bike and it's not unusual for them to bend or kink.

Mine was quite kinked, so I measured it up and found a "pit bike" one on Ebay the correct dimensions.

I have the Steve one Bondy so am not familiar with the type you have but I think Goudrons has the info you need.

Steve does a really well made rear spindle which will not bend should you need one.

How are you finding the OSSA TR77 Bondy.

yeah the ossa TR77 is a nice bike just getting to know it iv'e started doing jobs paint ect. Iv'e painted the barrel and head also. Am on the look out for a lid for the tool box an changing the tank and side panel as the tank is to nice to use fibre glass so I have a alloy 1 in good shape apart from a few dings with I will attempt to remove with a dent puller. Then paint. Any 1 know what a good size rear shock to buy am tall and heavy. Also what you guys doing to foot pegs mine as the standard ones.
