I have stock of both the traditional 3mm wire and the 2.5mm wire versions of my popular Lambretta rear brake cables with the adjuster crimped on. I've sold hundred and hundreds of these over the years, all with a lifetime guarantee. I have never had one returned.
They are available from ebay at £12 each, but Scooterotica forum members can buy them from me for £10.75. Please pm me if you wish to purchase. I take paypal as a gift.
(I will have stock at Wicksteed, on the K2 innovations stall)
