| Thanks
I'm in Cambridge.
When I was setting the clicky bits back to factory setting (they were massively out) I did wonder about this bit but it didn't make a lot of it in the manual, only about turning the top with a screw driver (which I did).
Looks like I've managed to miss a fairly fundamental part of the suspension setting here!
Is it simply a matter of putting a spanner on the top and turning it or there more to the adjstment than that? |
