So we had it explained to us by Cervelo that UCI rules dicatate a minimum of 4mm on each side of the tyre to be be “UCI approved” and that’s how they determine max tyre size. Running tyres with less them 4mm clearance on either side voids warranty.

@amey I’m super excited about the prospect - going to go for a custom paint and decal job, think. Probably will stick to non-di2 hydro Ultegra with a 2x chainset and 700C, as I’ve already got a 1x 650b Dynamo touring bike.
Such a good looking frame, been going mad saving stuff on the gram and doing mockups.
@MCamb Courier has picked up the bike already - a roll of the dice what they're going to say about the tyre width, but yeah - hope that it can be classed as 'accidental damage'. Wouldnt go for a warranty claim, just me being a little 'too precise' with clearance.

UCI rules
Not strictly UCI regulations, they don't mention tyre clearance. EN14781 does, so either Cervelo are confused, you are, or some UCI commissaire told Cervelo that compliance with EN14781 is a necessary, but not sufficient, condition for compliance with UCI regulations.
Running tyres with less them 4mm clearance on either side voids warranty
Hard to argue with that, but remember it applies all round the tyre, not just side to side.

During a few very slightly sludgy winter rides on my Supersix, I had noticed that the paint and possibly carbon had begun to skedaddle away from the insides of the chainstays.
Sent off some pics to my insurers and they very quickly arranged a specialist company to inspect! Pending a pickup and look from them, I think I might adapt the sunday Supersix bike into something a bit more all-road.
@amey and his CFR-505 is a big point of inspo right now.
