Like many, I imagine, I’ve been a GP4000 user for awhile and also been intrigued to go road tubeless. These are interesting to me, but I wonder the best way to determine the likelihood that a larger size will fit my frame. I’ve always been running 23mm.
I have a Felt B16 for Tri and wonder if a 25mm would fit. Obviously buying some and trying them out is the most certain, but are there any good sites to estimate the mounted width and height of the tire on a common rim (Velocity A23, for example).
I would upgrade my Road bike to 25 and keep the Tri on 23, but I still share an old PowerTap wheel between bikes and prefer not to swap tires so often.
I hope this isn’t too off-topic.
