TT Mode on the Davidson

Davidson MkV

This is the Davidson MkV in ful TT mode but regular wheels. I’d have to swap brake pads for carbon aerowheels which would take about 5mins. Swapping the rest of the bike kit actually only takes 10mins. The key is the cable splitters for the derailleurs and rear brake. I disconnect them and pull the stem and road bar off. Then I throw on the aero base bar/extensions/stem, tighten headset, connect cables. The 2 bars each have their own front brake caliper, so while I do need to undo and retighten the recessed nut i don’t need to tune the front brake. In close up pictures, you’ll see that the road bar has a front DA 7800 caliper while the aerobar has a SRAM Red caliper. I also have a second mast topper with a tri saddle positioned a bit more forward.

The trick is to use inline barrel adjusters for the 2nd bar and shifters (in this case, I mean the aerobar is the secondary and the road bar is the default setup). You need to cut the secondary’s cables and splitters very close to the default, and then use the barrel adjusters to get the secondary exactly like the default.

I haven’t actually assembled it as a fixed gear/track bike yet, but I’ve been tinkering with track handlebar setups. More later.
