Ridgeback project

Shimano HG20 7-Speed Cassette Sprocket 12-32T

The bike I have used most this last year (and intermittently over the last 15 or so years) has been my old Ridgeback Adventurer hybrid. It has been badly neglected since I bought it from Woodrups in Leeds and still has the original equipment and tyres. I jammed the rear mechanism in Islay earlier this year and it hasn’t been quite the same since although it still works. And on last Saturday’s ride to Temple Newsam with Julia and the Leeds Cycling Campaign easy rider group it started  jumping gears whenever I put any pressure on up hills. So I’ve decided to do the old bike up. Even if it costs £100 or a bit more it will be worth it as the equivalent bike now is probably about £450 or so. There’s no reason why it shouldn’t last another 20 years, which is more than I am likely to. So I popped into Woodrups today and bought a new set of sprockets and a new chain, the old ones are badly worn and stretched and may well be part of the jumping problem. I also bought the necessary tools –  a Shimano cassette tool and chain whip for removing the locking ring and a chain link tool. The free body seems OK so I will just change the sprockets and chain and see how that goes. I have bought a 12-32 rather than the current 11-28 to give me some lower gears. The the following video shows the technique of removing and replacing sprockets on the free body. It also shows how to change the free body too but I don’t think I will need to be doing this. But one day, you never know. I’ll try to find appropriate video demonstrations of all the various refurb tasks I undertake.

Parts:
Shimano Hg 6/7/8 Spd 116 chain £9.99
Shimano Cassette HG20 7 spd 12-32 £12.32

Tools:
Fat Spanner Chainwip £9.99
Fat Spanner Cassette wrench (Shimano) £12.99
Fat Spanner Workshop large link extractor £22.99. This item is quite expensive and cheaper ones are available. However, this is heavy duty with replaceable pins so should last. I’ll get a cheaper light weight one in due course for a travelling tool kit.

I’m not counting the cost of tools as part of the project as I intend to use them on furbishing Julia’s Ridgeback hybrid in due course and other bike projects in the future. I bought a Park Tools PCS-9 – Home Mechanic Repair workshop stand a couple of months ago for £89.99.

I’m keeping a record and notes on the project and other maintenance issues on a page Maintenance. It is commentable so any advice or shared experiences are welcome.
