Description

Epic rides are just that -- epic. If you scrounge through our "What's New" section you can read about the trip we took to the Alps to watch le Tour in 2003. It was epic indeed. Day 1 was something like 110 miles with 4 Alpine passes and near-certainty by the end of the day that we'd be stuck sleeping on the side of the road thanks to our over-ambitious itinerary and sheer ignorance about the fact that real cols can take upwards of 2 hours to climb. And our second day nearly stopped before it started. We were slated to ride from Grenoble to the top of Alpe d'Huez to watch the mountaintop finish there, but 15 miles into the ride -- alongside the longest traffic jam we'd ever seen -- we got a gunshot-loud rear puncture on the interminable false flat that leads from the remnants of civilization into the harshest riding terrain on earth. We had only one spare tube, but worse was the fact that we'd repaired every roadside puncture in the last decade with handy, dandy CO2 cartridges. Since we flew to France we couldn't bring along CO2. Instead we carried one of these -- a Topeak Master Blaster frame pump. It was sheer terror for us: Would we rip the valve off our only spare thanks to all the leverage we'd be putting on the valve? Would we nuke a rotator cuff given the reputedly small stroke volume of a frame pump?

No.

And no.

Rather, it took us only about an extra 30 seconds to air our spare rock hard in comparison to what it would've taken with a CO2. The valve? It was fine. Our shoulder prognosis? No problem, not at all. Given the length of the Masterblaster's barrel, it brought our tire up to good pressure with surprisingly few strokes -- a beauty of the fact that this is a real frame pump, not one of those mountain biking mini-pump jobbies. Long barrel = generous stroke volume. In short, the Master Blaster is the bomb. We got to the top of l'Alpe with abundant time for a 4 course lunch and a 20 Euro bottle of Evian before Iban Mayo passed us by resplendent in his orange Euskatel jersey, a full minute ahead of the remnants of the peloton.

The Master Blaster comes in 4 sizes -- choose the right size based on your frame size: Small for 43-49cm, Medium for 49cm-54cm, Large for 54cm-59cm, XL for 59cm+. It comes with an integrated seal and dust cap. It has a padded pump head with an internal handle lock for a solid grip. The barrel is aluminum to keep it in the sub-250g. It was there for us in our moment of need. This is the pump you want.

Here's what others have to say...

Is there any testimony to exactly how long...

Posted on

Is there any testimony to exactly how long each size pump is? I have a nashbar carbon frame and want to be able to fit this under my top tube, and the length between the two contact points, one being behind the headtube and the other on the seat tube just below the top tube, is roughly 47cm.

Responded on

Hey Nick,

I believe the length on each is as follows:

Small - 17.1 Inches
Medium - 19 Inches
Large - 21.1 Inches
XL - 23 Inches

Hey Nick,

Sizing Specs:

Small
Fits 43-49 cm Frame Sizes (16.9"-19.3")

Medium
Fits 49-54 cm Frame Sizes (19.3"-21.3")

Large
Fits 54-59 cm Frame Sizes (21.3"-23.2")

Extra Large
Fits 59-64 cm Frame Sizes (23.2"-25.25")

Responded on

I think these sizing specs are not quite what I was looking for. I got the pump I ordered yesterday and found that the pump's handle has a spring inside and can be compressed over the physical chamber of the pump in order to expand and apply force to each side of the mounting area. The sizes when the spring is all the way compressed are listed on the package for the small as 375mm to 425mm, I may have the first number wrong because I am not near the pump. But regardless of this, the package indicates that the small pump does not extend past 425mm, whereas the measurements above say that the max for the small is 490mm. I think someone simply converted the frame sizes to inches.

Saved my life more than once

  • Familiarity: I've used it several times

This is a great pump for the value, Fits great on my specialized. I was carrying around a huge pump that would barely fit in my backpack for the longest time, I finally bought one of these bad boys to always have attached to my bike and it was definitely one of the better decisions I've made. I'd recommend to anyone who is a commuter, or just on the road for long spans of time.

Do you have an example on how this attaches...

Do you have an example on how this attaches to the frame? Could I get a smaller size than what my frame calls for with out issues?

Best Answer Responded on

You need some tension on the ends... there is a little bit of spring in the handle that allows for that. It isn't tight enough to hold without the strap, but combine them together and it is a solid mount. I wouldn't go small or you won't get a good fit.

Light, Durable, Capable

I have had this pump on my road bike for 10 years, used it countless times and it has never let me down. Dual settings help you get volume fast and then high pressure at the end. Stays out of the way and doesn't weigh much at all. I prefer this setup to CO2 because no matter how many times you flat you always have what you need!

Make sure you get the right size and it will fit tight and not rattle at all. I got 8 years out of the included strap before I had to replace it - no complaints though.
