Swapping flats for drops on a tandem

You may struggle to find adequate clearance for your tyres and suitable mudguards using mini V-brakes, which in any case can feel a little spongy used with road brake levers (see TRP CX8.4 review Cycle Oct/Nov, 2016).
If you wish to stick with the V-brakes and would prefer to use STI dual-control shifters, you may have to fit Travel Agent cable pull adaptors as the levers and brakes are not compatible.
Instead, I’d recommend using Shimano bar-end shifters and V-brake-compatible drop-bar brake levers from Cane Creek, DiaCompe, TRP or Tektro (pictured). If you prioritise dual-control shifting, consider using cantilever brakes such as Tektro’s CR720 (reviewed Cycle, Oct/Nov 16).
