And an update.
Shock arrived - built and dispatched By Mr Risse himself!
(superb service - cant recommend them enough - the shock is good too!)
Fitted and fettled (it actually arrived with near the correct pressure for my weight too!)
It was with trepidation i took it out for a spin - some 15 years of a wait, will it be what i want, will i like it, will the other half find the receipts carefully hidden.. so many questions!
Well off i went a 3 mile war up on the backroads to the forest - nothing exciting on the way there - bumps and potholes absorbed with no notice.
then to the forrest, I decided to ride my favorite short track backwards - my reasoning riding semi technical uphill would find out if it was good or not vs a smooth climb and a blast downhill. Bottom line it works nice - it felt like a big tyre on the back. bump were soaked up no matter what i was doing powering up a climb or coasting along. in fact i found i was spinning out in a36 x 12 and shifting to the big ring more than i would on my hard tail's/rigids.
More rides are needed to dial the position and tweek it a little but it's nearly there
