Ingrid Jwrote a review of Crank Brothers Gem Hand Pump on August 7, 2019
Familiarity: I've used it several times
this little guy is tiny in size and lightweight but is efficient and gets the job done. I've forgotten my pump before and this little pump was super easy to use and i didnt feel like i have to pump 300 times to get the air i needed. i always have it in my bike bag and i forget its there because its so light!
