Bought a Titanium rear caliper piston and seal. Said it didn't fit his rear caliper. It does fit this bike as I've sold loads. First message was that of extreme anger. Extreme anger!
I'm guessing he either didn't know how to fit it, or perhaps the bike is modified or he thought the rear piston would fit the front caliper.
I offered a 'return on me' service where I automatically pay his postage and I even offered another piston size if he supplied the dimensions to what he actually needed. He ignored the kind offer and left a negative feedback saying this "Avoid at all cost, supposed to fit dtr, clearly doesnt"
So, this person is just a cunt and should be added to your blocked buyers list.
