"I've had this pump for 8 months and luckily not had to use it until today but was extremely impressed with its performance. It's a little larger than some people like to carry with them but worth the size if you can fit it somewhere (I ride a 56cm frame and it fits nicely on the upright with about 5cm to spare).
The construction is very nice and it immediately feels like a quality product when you pick it up. Despite the size it is pretty light yet feels very solid when in use. The pumping action is very smooth and easy, and the pump can easily deliver over 100psi. For example today it took only around a minute to put 100+psi into a 23mm tyre and this was without any significant effort. I am a fairly strong chap but this really took very little strength to use.
The little foot stand is useful, although awkward to use in road shoes and the ability to adjust the handle to sit in the hand makes it really easy and comfortable to pump. I doubt the gauge is as accurate as a larger pump and a little awkward to read but good enough to do its job.
I would definitely recommend this to anyone who wishes to be able to pump up a tyre out on the road without too much fuss. Certainly when training it's so easy to use that it really makes compressed air pumps unnecessary."
Pros: Attractive, High Quality, Adjustable, Lightweight, Versatile, efficient
The racing classic and handmade in Germany. The name Grand Prix has become a brand of its own in cycling circles worldwide. The Grand Prix is the classic tyre marking quality and performance. A great all-round wire-beaded tyre for all-year use.
"Bought a pair of these,both in perfect condition with no splits or nicks. Aside from being very tight to get on I have no complaints. Good grip in the wet and have done nearly 300 miles in 2 weeks without any punctures yet. would definitely buy again."
