Just fitted the rox risers to mine: not tried out yet, as I changed the top brake hose for a venhill item.
Paid about £35 , 2 day delivery. Venhill stuff is great.
I could not fit these without altering the top line, people said it ould be done, but I could not manage.
My issue was I was getting back ache after stretching too far forward.
Taking bike to Faro through France this year, so need to be comfy.
