This evening I picked up a new-to-me frameset, ostensibly to replace the Viner Mitus 'winter' bike I have. Today's audax clearly demonstrated the limitations of using a pure race bike as a winter bike, with the tyres constantly scraping the mudguard mounts and eventually clogging.
It's a 2018 Ridley Fenix SL frameset. Son no. 2 has a 2017 one, but the standard version. The build will be done either over Christmas/New Year if the weather's awful or at some point when I can get the time to swap components between the two. I paid probably more than I would normally but as it's the SL version that's OK to me.
This is the Viner for comparison. Looks good but completely inappropriate for winter use with far too little mudguard clearance, particularly at the brake mount points/fork:
