Bike fit / correct riding position

Pete; that is the one Scheritt suggested I will give them a call today. How was your experience with them as service and how is the product? Any pic etc?

These look like mine - Sprint

After giving them my prescription details and choosing the model/lens type ( they only had about three different models then ), they arrived pretty quickly and have lasted through years of everyday use so far ( road/off-road/beer garden ). I did have to glue one of the nose grippers back once, but that was after about five years.

£170 for a single prescription now vs £125 when I got mine. Still seems like comparatively good value to me. Mine are photochromic too, which has been far less of a faff than swappable lenses.

I suppose the major downside is like with anything mail-order, in that you can't try on multiple pairs in a shop first.
