Finished cabling my trike, overcoming some indexing difficulties with zipties routing the rear cable through/ around the axle loops. Just need to tape the bars, either red or white, to go with the British Racing Green and white transfers.
Now that it is finished, I've taken stock of what has been replaced since I bought it as 'fully serviced and ready to ride'. The only components that weren't worn out or incompatible and therefore could be reused were the wheels, rear axles/ cups, inner tubes and the Shimano 600 cantilever brake and cable stop. Everything else has been replaced, including the gear hanger, seatpost bolt and seatpost (wrong diameter!). The Ultegra Octalink triple cranks, BB, brake levers, standard reach dual-pivot brake, mudguard and Brooks saddle came from the garage stock but everything else was bought for the trike.
Unfortunately the cheap headlight on my trike emitted a funny smell and stopped working. Hopefully the Enerloop AAA batteries haven't been too affected. They are in the smart charger being capacity checked.
