Mounting pump on seat stay???(3 posts)

Mounting pump on seat stay???Dark Sonix
Jun 17, 2002 11:13 AM
In the past few days, I have seen some folks with frame pumps mounted on their left seat stays. I would like to do this (I have to carry my bike up and down three flights of stairs and the top tube mounted pump is a pain), but have reservations about the pump slipping out into the wheel.

Is this an unfounded concern? Anyone have bad experiences with this?

I used to mount a pump on the left chainstay of my Calfee. I never had a problem but the fear of a wheel disaster led me to add small velco straps at the top and bottom of the pump. I've subsequently weaned off the pump and now carry only CO2. After 25 years of biking with a pump it has been a hard transition.

Disasters don't strike often, but a frame pump into your rear wheel at speed would be one to avoid.

In the early days, when you carried your bike more than you do now (not more than I do now...), a lot of people mounted their pumps either along the seat stay or behind the seat tube, between the tube and the wheel. I never had one fall out, but I always worried about it.
One possible solution: For 7 bucks at REI, you can get a couple of pumpholders, rubber blocks with Velcro straps to attach to the tube. Made by Zefal, and they have some catchy name I can't remember. I use them on my Atlantis, which has a top tube about 1/2 inch too long to hold the longest Zefal hpX pump. A stay would be skinnier than they're designed for, but they could be tweaked to fit.
