Cheers Paul, i can probably buy one but don't know what the thread size is and don't have an imperial thread gauge and when i went to get my digital vernier out the battery and spilt its guts so ordered a new one.
When i got home yesterday my seat had arrived
Both myself and SWMBO have tried it for size and as expected it will need widening a tad..... But I'm happy with the overall shape and the rear rake is less than anything i have tried so far so will hopefully allow the seat to got back a little bit more.
TTFN
