Hi, my girlfriend has been riding my road bike (Specialized Sequoia)
and recently she has been getting lots of flats on the rear tube. I've
replaced the tubes with new ones (various brands, Bontrager,
Specialized, even Slime) but the tires still go flat at the end of the
day. I consistently fill them with the right amount of air for road
tires. I've also tried different rims/wheelsets but the problem still
occurs. I've also replaced the tires themselves (went through
Hutchinsons, Michelins, Armadillos) to no avail.
She's not heavy at all, ~110 lbs, so I'm not sure if it has anything
to do mechanically with the bike or with the way she rides. She only
rides it on asphalt and hardly ever over debris and I haven't seen any
punctures in the tires themselves. I've noticed that a couple of
times, the puncture is on the tube around the valve but I've run my
finger across the inside of the rims and have noticed no burs or
protruding spokes. The rim tape is still intact.
She has experienced no problems with the front tires however so I'm
puzzled as to what it could be. I'm scratching my head as I watch tube
after tube go in for recycling. Not to mention she getting frustrated
having to watch me replace the tubes at the end of her ride.
Are there any special considerations for a female cyclist on a road
bike that I would need to buy different types of tubes because of
center of gravity, etc... I know I'm reaching a bit there but I'm not
trying to be sexist in any way.
Frustrated (but experienced) tube changer.
