Replacing Moulton Series 2 'F' frame plastic cable guides

Functional and less obtrusive

Those of us familiar with the early Moultons know that each model (Series 1, 2 or 3) is a mixed bag of pros and cons that silently tell the short, turbulent story of the most original bike of the twentieth century. The first 'F' frame of 1962 had the formula right, but in execution it wasn't quite 100%. The problems were ironed out progressively, and by the latter part of 1965 the Moulton had evolved into the definitive 'Series 2', fully sorted at last. If your bike is one of these you may well feel chuffed, especially about the strengthened swingarm that replaced the fracture-prone version on thesteel cable guides of Series 1 f frame moulton earlier bikes.

But it wasn't all good with the Series 2. The trouble is that by the time the original Moulton was sorted, sales were falling with the emergence of competition – most notably the Raleigh RSW. Moulton was losing money and had to cut costs, and the bikes suffered for it. For example, the Deluxe models had their tasty alloy parts replaced by heavier steel equivalents, and the distinctive 'billiard cue' paintjob went by the wayside.

But if you're like me, what annoys you most are the horrible white plastic cable guides that came with the Series 2s. The earlier bikes had tidy steel loops brazed to the frame, but that must have been too costly to survive the austerity campaign. A shame, as I think the plastic guides would have looked cheap and nasty even when the bikes were new (judge for yourself from this advertisment). As you'd expect, the survival rate of the plastic cable guides after 50 years isn't good, and your Series 2 may only have a few useable ones left; how many Series 2s have their cables tamed by zip ties? And where a frame isn't marred by broken cable guides and zip ties, then it's pocked by little holes where long-departed cable guides once lived.

What to do? Exact replacements can't be found, and the search goes on for the neatest, most effective way to replace them. So here's Bootiebike's way: Essentially, I've fabricated some little brackets from a length of right angle plastic trim moulding, obtained from a hardware store. Each bracket is held in place by an automotive trim 'canoe' clip, which fits snugly in a frame hole.

Notes

I've aimed to make the illustrations below tell the whole story, so it shouldn't need much explanation, but a few notes are in order…

Good luck!
