I've converted 2 old Hercules 3 speeds to 700c, I was only able to fit 25c tires though with the fenders in place, they work just great, all in all, but it would be nice to get some bigger tires on the rims. Both those bikes have the nice Hercules Chrome fenders so I did want to retain those, I did bend them around where possible to get as much clearance as possible, but going to a 28c tire did result in rub, not the end of the world, but I'd love to fit 32's on those bikes.... I converted a Raleigh Sprite to 650b with which is a great bike, and fits 38c tires just fine, but I do like the look of the bigger 700c wheels on these old 3 speeds.
