The spring in the pump handle is there solely to keep the pump in the frame. Security will depend on
how slight the amount of compression is. The top tube will presumable need slightly more grip than
down the seat tube, which may mean that there are some frame sizes that fall between the available
pump sizes. I have used an HPX4 under the top tube of a 57.5cm frame with a similar peg on the head
tube. This was a fairly tight fit, and I had no problems with security. However I did find that it
rattled a bit (inside of handle against outside of barrel), so I started using a velcro strap, which
would also be a solution if your pump doesn't fit as snugly as mine. I got my last strap from the
CTC shop - a Zefal "Doodad".
