TOPEAK TURBO MORPH DIGITAL PUMP
The Topeak Turbo Morph digital pump includes some great features including a digital readout, high volume pumping in a small-sized pump. Basically, a compact floor pump you can easily carry with you on your bicycle.
I helped host a cycling camp several weeks ago and thought that the camp would be a great opportunity for a dozen cyclists to use and test out this pump.
A couple things quickly became apparent. This pump is optimized and target for the Mountain Biker which includes cyclocross and gravel. This pump is a little large to fit on a road bike, but, for those weekenders who ride endurance-type road bikes, this makes a great pump.
It is easy to use and pumps up a tire quickly. Although I have not had a chance to test on a MTB tube, the road tubes (700x25c) too 105 pump strokes to fill from 0-105 psi.
Understanding that this is primarily a MTB pump, I have two ‘nit-picks’ that if remedied, would make for a better all-around pump.
1) The foot peg rotates past 90° which might be a plus when pumping on an uneven surface, but, if pumping on a solid and level surface, the pump flops around from side-to-side when pumping.
Figure 1 shows the foot peg fully extended to 155°. This might work well on uneven ground, but a better solution would be to add ‘detents’ so the foot peg would stop at 90 ° (Figure 2) and then fully rotate out to 155°.
2) The base of the pump is solid plastic which again, might be ideal for pumping on an abrasive surface, but, if pumping on a smooth solid surface, the pump wants to slip around, especially when getting up to and past 100psi (7 BAR).
Figure 3 shows a hard-plastic base. Even though there is a small rubber piece attached to the foot peg, it is not large enough to prevent pump from sliding around on a smooth hard floor. A solution might be to redesign the base slightly so that a ‘removable’ rubber piece could be added.
How did the pump work out?
The pump was in use for 6 days and saw considerable use. All-in-all everyone liked it. It pumps easily to about 90psi, then moderate resistance starts. Even though the digital readout goes to 160psi (11 BAR), after 105psi there seems to be exponential resistance. But, 105psi is more than enough for a MTB tube and more than enough to get a ‘roadie’ back on the road.
Summarizing the comments; “The Topeak Morph Digital is a solid unit. Easily pump up a 25c GP4000s tire with butyl tube from 0 to 105 PSI in roughly 100 strokes. The gauge is accurate and useful. The foot plate is not as sturdy as it could be, but overall it is a very serviceable unit.”
Yes, with the caveat that it is a MTB first and a ROAD pump second. It is quality built to the point of being used as your standard “pre-ride top off the tires garage floor pump.” This pump will last you for years and years.
