Ah, ok.
I have no experience of these gadgets though. I fitted progressive springs to my RC and they have a decent feel at the front. On my RB I had Maxton work their magic on the forks and the front end is absolutely superb.On the track they perform superbly, never bottoming out even under the hardest braking and always giving feel and feedback. They are matched to my weight and backed up by a set of Maxton’s own custom made rear shocks that are again just superb. A dearer option but highly recommended.
