Has anyone here routed mechanical shifting through an SL7? Is it a fool's errand?
I have an SL7 on the way. I'd love it to be Campagnolo but don't want to pay for the new $5k wireless groupset. Chorus or Record would be in budget.
I'm just skeptical about the routing and getting the derailleurs to shift correctly as I struggled with routing my 11 speed through 3T handlebars. (Admittedly 3T internal routing on those bars sucked horribly. Just two round holes. No channels or anything.)
I just built up an SL7 with a mechanical Campagnolo H11 group. It was a bit of a pain in the butt, but it wasn't due to the mechanical shifting. Running the shift cables wasn't the difficult part, it was the hydraulic cables that were the biggest hassle. Normally, the hydralic cable is routed through the hole in the fork or chainstay, and then up the frame out out through the headset bearing. The compression plug and spacers are then threaded over the cables onto the headset, and the cables can then be run across (or through) the handlebar, and the finally attached to the levers. But Campagnolo H11 uses banjo fittings at the levers which are too large to run through the hose holes in the frame/fork (and too large for many internal routed handlebars as well). So the hydraulic cables have to be run in the opposite direction from usual. First through the handlebar, then the spacers, then the compression plug and headset bearing, then through the frame and fork, and finally out of the frame near the calipers. So, kind of like building a house by starting with the roof, and finishing with the foundation. In contrast, the mechanical shifting cables are quick and easy addition.
