You wanted to know what my Kenda Flintridge Pro's measured. I am claiming Senior Moment here and will erase after I see your reply.
Front looks like 41 mm
Rear looks like 41.5 and yes they have been on for over a month so they aren't going to stretch out anymore.
What thread was it BTW?
Ha I can't remember either but it was over on BF. Thanks for the info!
