Speedo not working?

[declan]

So this was the first speedo cable I installed and it don't work while riding or pushing for that matter But if I disconnect it from the wheel and spin the cable the speedo does read anything I could have done wrong or is the drive screwed?

Sounds like the speedo drive, but it's not something I've really heard of.

@Calum any chance that the speedo drive is too gunked up there's some pretty dirty and really tacky grease in there

@declan Yeah, it might just be a case of not seating right.
