Also hinges lock really positively which is what's needed in a fold-able ladder, but it might help with a longer lever to get hold of when operating the hinges,,just a suggestion. I have been very happy using the SRAM X5 with several friction systems with very wide ranges that other derailleurs were unable to handle. Weighing in at 140kg, with a tough 3 point locking system - featuring a pick and drill resistant locking mechanism, this all-metal weatherproof shed is designed to keep your garden tools safe and dry no matter what the weather. And you are often able to get by with less front shifting, as the middle ring will handle most conditions. Designed for an amateur angler or occasional fisherman with a reasonable level of equipment, our home fishing tackle storage is designed to keep your fishing gear safe, secure and dry.

If they're friction, almost any derailleur will be compatible, so I'd recommend a Shimano one, probably one of the Deore-level ones.

I'm with you on the 11T, thats just insanity for most riders, further they wear out really fast and take the chain with them. You're right that these days, the OP is more likely to find a good Shimano unit for the job than a SunTour. This could pretty straightforward or extremely complicated and costly depending on what sort of hub, rear derailleur, and crankset you have. Is there a difference between those drive chains related to efficiency, ease of use and reliability?

stone, you can be confident it won’t move in extreme weather or be pried up from the floor by thieves.KRAUSE seminars convey all the knowledge to be able to carry out the required tests as a qualified person and to document them.
