I have some Hope Big-uns spoked up to some Sun (Sunn?) Rhino rims that I have had for quite a few years now from new and I reckon they must be getting towards being retro!
Ha ha, i've got retro parts!!! Never really thought of Hope Big 'Uns being retro til now, got them fitted on my FSR, with C2 Hope Disc Brakes. Oh, and they are RED!!!
I'm still rockin' a set of big un's and an old style black C2 caliper with nice and chunky hope levers (the ones that became 'sport' levers) on my main bike. However I think these fall into the category of OLD (and reliable mind) rather than retro
