Out of interest - the recently ‘old’ generation of the supersix (e.g 2018-2019) - does anyone know what the actual weight difference would be between a hi-mod and non hi-mod rim brake would be? I think (from memory) the non-hid mod was still pretty decent.

I’m only asking because I’ve got a 2012 ‘normal’ supersix and there’s quite a few of the newer style around on eBay, but tempted by a hi-mod option but they are quite a lot pricier. Basically I think the main benefits to swapping for either version would be

1. Lighter (the old supersix frame set is just over 1kg, the fork 450g)
   
2. Hopefully more comfortable (the old frame set is very stiff and has a 31.6 seatpost)
   
3. Fractionally better tyre clearance! I only want to be able to fit 28mm tyres without fear
