Topeak Mini Morph pump



Reasonably priced but doesn't achieve higher pressures with the same efficiency as a midi pump

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Topeak Mini Morph splices the best features of a track and mini pump - you know, in one of those experiments involving matter transfer demonstrated by Seth Brundle (Jeff Goldblum's unfortunate scientist in David Cronenberg's visceral remake of the Fly).

I would love to say it was the first of the pint sized inflators to conjure a genuine 160psi from its small, yet perfectly formed body but alas, biceps screaming with lactic acid and after seven minutes' sustained effort, I conceded that 105psi is pretty much tops. On the plus side, it's a pretty unobtrusive housemate in most luggage and the external hose is a nice touch.

Measuring 26.4cm and weighing 180g, we're at the upper end of mini, cruising squarely into (more efficient) midi pump territory. That said; build quality and design are generally better than I've come to expect from compact pumps. It has a stout aluminium barrel but I'm not sold on the folding footpad, which quickly showed evidence of warping under load. An aluminium loop would have inspired more confidence and the bottle mount is at the expense of, rather than in conjunction with a cage.

Mercifully, Topeak offer a zip-tie alternative while the flexible rubberised hose and extended locking head are thoughtful. The latter not only incorporates Presta and Schrader but old-fashioned woods stems too -perfect when pooling tools for on tour weight and efficiency. I managed zero to 60 psi n approximately 500/600 strokes and five minutes. Perseverance and a further 350 strokes returned 105psi, which should be adequate in most contexts, although a decent midi pump costs but a few pounds and millimetres more, reaching comparable pressures with rather more ease.


Reasonably priced but doesn't achieve those higher pressures with the same efficiency as a midi pump.

Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

"The smallest Morph is still big on features.

Fills both fat and skinny tires with ease, fold out foot pad for hassle-free inflation." Broadly agree but a metal footpad might prove more reliable in the long-run and in practice I couldn't nudge past 105psi.

Generally to a good standard but footpad looks a possible weak-spot.

Rate the product for performance:
Rate the product for durability:

Looks promising, although I suspect the plastic foot-pad might prove a weak-spot in the long run.

Rate the product for weight, if applicable:

180g by my scales.

Rate the product for comfort, if applicable:

Superior to most of the pint-sized breed given the folding T handle and similar detailing but in my experience there's always some trade-off between size and inflatory prowess.
