Road Bike Frames, Wheels & Components / Rim brake road bike frame with at least 28mm tire clearance
« on: March 27, 2024, 05:33:06 AM »
Hello,
first of all. This forum is a great ressource, hats off to all your effort and the collective knowledge presented here!
I fear my question is a bit of a niche question as rim brake bikes are dying out steadily... but still... I live in a relatively flat area (Berlin), I am not eager to ride in rainy conditions if I can avoid it, I like to experiment with bike geometry and also fear the necessary maintenance disc brakes require. Moreover, I have lot's of rim brake specific spare parts lying around here... tl;dr: I am looking for a rim brake frame.
But: Berlin's roads are rarely smooth and there are also lots of cobbled paths. Coming from a ultra stiff early 2000s aluminium frame which can barely accomodate 23mm tires @15C rims (Pro-Lite Cuneo GP), I would LOVE to have a little bit more comfort. From browsing through all the china frame manufacturers (Dengfu, Hongfu, TanTan, Workswell, etc.) I know that most of their rim brake frames only accomodate 25mm tires. I myself own a Hongfu FM-088 which is rated as "25mm" and leaves only minimal clearance with Vittoria Corsa 25mm @ Campa Zondas 17C and I always have to deflate the tire on the rear wheel once I want to remove the wheel, otherwise it get's stuck in the frame. tl;dr: I know that it's maybe a hopeless request.
To sum it all up: Does anyone of you know a rim brake frame that accomodates 28mm tires?
(even better when it has threaded BB, endurance geometry, round seatpost, common headset measurements [eg IS42/28.6 | IS52/40], but that's for another time)
