easy clutch lever pull

chasbmw said:
So talk to me about clutch lever fulcrum points… I have a prewar Rudge and the clutch is pretty hard, one of the variables to clutch pull effort is lever fulcrum points. Most British bikes have a fulcrum distance of either 1 1/16” or 7/8 ths. Which gives you a lighter clutch all other factors staying the same?
Thanks for your help on this non Norton matter

Oh he's got eyes for one. This at the Quail in Monterey last April. He's been hitting the weights and is a lot stronger, just 18 months on.

@ludwig passed on a great tip some time ago which I adopted on my Morini on/off dry clutch. He uses a “Linear” brake cable which are used on BMX bikes. Instead of the normal spiral wound steel in the outer, it has individual wires running the length of the cable. It dramatically improved the feel of the clutch and is an easier pull. The one I got is called “Odyssey K-Shield Linear Slic Kable BMX Brake Cable” which has a Kevlar reinforcement to stop it bursting through the strands.

@cliffa @ludwig : just looked it up the “Odyssey K-Shield Linear Slic Kable BMX Brake Cable”. I’ll give it a try. Did you use the 1.5 mm or ?
Txs much.

Hi, yes It has a 1.5mm inner cable, but they are pre stretched if memory serves, so should be plenty strong enough. A couple of tips - ideally you will need proper shears for the outer if you need to shorten it, as they are pretty tough (side cutters won't work in my experience), but as I didn't have any, I used a cut off disc in a rotary tool. Make sure you deburr the inside of the cut end though, whichever way you cut it. These kind of cable don't like tight bends, so keep the routing nice and gentle (perfect on a Commando). And lastly, they only come with a nipple fitted to one end, so you will need to solder one on or use a solderless one. (on my Morini, I used a solderless, and then added the brass inside and screws from a toffee block connector behind it, just to be sure it wouldn't slip.

Hi Cliffa, many thanks ; points duly noted👍. You’re correct re “pre-stretched”.
Best.
