Brompton cable gatherer This cable gatherer is for Standard 5mm brake outer. a 6mm outer (for Kevlar or braided outer) is also available. Cable Routing Correct routing of the control cables is essential if these are not to be damaged during folding. All cables MUST pass in front of the handlebar, to the left of the handlebar stem and to the right of the main frame tube. The front brake cable must pass: a) through the body of the cable gatherer, CABGATH (Note: the outer cable is in two parts) b) through the forward cable guide, CGF, and c) to the left of the front mudguard (for a C-type, see note below). The rear cable(s) must pass: a) through the ring on the cable gatherer, CABGATH, b) through the centre cable guide, CGC, c) inside the tube TT, d) through the rear cable guide, CGR, as shown, and e) for the brake cable, BRCABR, inside the tube SS The gear cable(s) GCAB should lie below the brake cable, BRCABR. If there are two gear cables, then the derailleur cable should lie below the hub-gear cable. When replacing a cable to which a dynamo wiring loom is ttached, cut the tie wraps holding the loom to the old cable, and re-tie the loom (at the same spots as before) to the new cable: on a rear cable the rearmost tie must lie just aft of the CGC, not in front of it. (If the loom is a Mk 2 type, which reverses inside a rubber sleeve just under the CABGATH, use two tiewraps here, and pull them extra tight to prevent slipping.) Note: For bikes without mudguards: the LH front fork will either have a fender/mudguard disc or a brazed-on wire loop: the brake cable must pass outside these (and not through the loop).
