Sick of the weeping caliper issues on my shimano 4 pots, i also upgraded to some Dominion A4's. One thing i wasn't aware of was the I Spec EV thing that my bike's controls used. Essentially the brake controls are the priomary bar clamp mechanism and the shifter and dropper lever both piggy back off that. With nowhere to mount them, luckily Hayes has an adapter for the shifter but not for the dropper since shimano seems to be the only one making a Ispec dropper lever. Found some conversion bar clamps for like $40-50 but thought this would be a good, low stress candidate for a 3d printed clamp. Whipped this one up and seems to be fairly solid. Will see once i get some dwell time on it though.
