What year Gwing did it come off? I have old weak hands, I would like to get both levers closer to the grip.
I don't know, a recent one I guess. I was at the retailer's (12' km check up for oil and filter), he grabbed it in his spare parts stock. I suppose any adjustable lever would do, it's really not a big deal.
My hands are strong but not that big

I'm pretty sure that with this brake lever I can brake harder because it's closer to the grip.
