friction shifting ideas please – one for the bodgers
I recently put a friction shifter on my bike on for the rear mech – and decided I prefer it to indexed. Its a nice suntour thumbie I have used.
Unfortunately I only had the one – I would like to go to a friction shifter / simplified for the front mech – even more advantages being able to trim it. I only have two chain rings so the cable pull required is not very much. I tried using a poplock lever but the pull ratio was all wrong – required far too much force.
Anyone got any bright cheap ideas so I can get rid of the clunky indexed lever. Quite happy to bodge something up. I would only shift a couple of times a ride on the front

Gripshift for the front mech (you use it left often and can trim). Thumbie for the rear. I use an old gripshifter on our tandem for the drag brake as it has settings from 1-8 and stays on when needed. Of course it also has those classic Shimano DX friction shifters front and rear 8)Posted 6 years agosimon1975SubscribergusamcMember
how about something like

can you use a motorbike clutch lever, bolted to the frame, with the lever bolt done up really tight, or you could glue a small spanner to the lever bolt for on the hoof adjustment …

Ah, I used to mount it under the bar as well. Proper old school
I can send you this if you like:
It’s a left hand thumbie that has seen better days but should still work. I took it off a bike only a few months ago. It’s missing the screw adjuster for tension and is a bit stiff but should be ok. FOC if you want it as it’s just in my box of bits at the moPosted 6 years ago
