I've had Evoluzione slave cylinders from Casoli for both my Ducs. Quality kit, highly recommended as above. Does what it says on the tin. One warning, when I thought one was letting in air (it wasn't), I called Casoli to order a replacement set of seals. They treated me like I was asking for something impossible. Eventually though they did me a swap for a complete new kit, so they came right in the end. Spinoli |
