TopeakRaceRocket MT Bike Mini Pump, Fits Presta and Schrader valves

This is a nice pump. After having another frame pump let me down on the trail twice, I bought this one based on the recommendation of some mountain biking sites. I like that the pump doesn't rattle at all and inflates bigger tires reasonably fast. I typically mount all my pumps handle up, but I feel like this one could be fine handle down, due to how it's constructed. My only gripe is that threading the head onto a Presta valve can take a little finesse. This isn't that big of a deal, and I have yet to have a valve come unscrewed. If it were to, it's nice that Topeak integrated a valve core tightener. All in all, I'm pretty happy with this pump.

Buen producto. Se hace fácil cargar aire a la rueda cuando no se cuenta con la bomba o compresor. Compacto.La extensión flexible evita forzar la válvula

Nicely designed and compact pump. Material used seems to be very good too.But I had an issue with the first two received. The hose, no matter how hard I tried, refused to extend. The 3rd one finally worked, and it’s great. There may be a quality control issue, or a certain lot may have this issue.

Biggest problems with every other mini pump I’ve owned have been 1. awkwardness of pump on valve (pumps wobble, stems and cores get bent) and 2. leakage / diminishing returns-per-push as tire pressure nears “acceptable.” This pump solves both. The hose link solves the awkwardness problem, and the pump’s threaded connection (plus a presta-schrader valve adapter) solves 2. Lossless pumping, at last. On casual rides I often leave CO2s at home now. This pump is fast and delivers great pressure. I only wish it were 25% smaller/lighter.

I have ridden bikes for about 40 years now (I never quit from that first bmx in ~1980), most of that on mountain bikes. Last 5 years I have averaged about 6k miles annually. I’ve had this pump for about 6 months now, used it at home a couple times to make sure it was up to Topeak’s typical high standards (it is), and have now used it on the trail a few times. I do use CO2 most of the time if a tire is completely flat, and I would recommend carrying CO2 if you ride a lot/time is of the essence. I carry this for slow leaks on training rides when I don’t want to burn my CO2. It will handle even high volume tires without exhausting you - quite a feat for a mini pump.

Got this pump after a friend raved about it. A bit larger then some but works well for a mini pump. It’s a pity that they show the hood but did not deliver the gold.

Tamaño , función, y materiales excelentes.

The pump in this add is a great little pump. I already had one and wanted another. Unfortunatly, the seller didn't send me the pump in this add. They sent a different larger model. The most appealing thing about the pump was the small compact size. I should mention both are good quality.

Se ve que es una buena bomba de calidad a diferencias de muchas en el mercado que son más sencillas o de baja calidad, está la pongo 4 estrellas por qué , no llego el color publicado, llega en color negro y sólo la he utilizado una vez y si me funciono muy bien.
