Force lever already has that type. I was wondering is the red 10 speed right lever ive got would also take it, but doesnt sound like it will. How much do you want for the spare pair/how much do you want for them? I'm in London
yeah you won't be able to get them to match if that's what you want.
You can have them for nowt if you can pick them up from W1 in the day or N16 in the evening.
Those cross ones you linked to should work for the Force lever. I've got a spare pair if you're in London.
