My Topeak Road Morph G Pump Review. I bought this bicycle pump because I was tired of being stranded using a small bicycle pump with a capacity not much larger than a sharpie marker. In the unfortunate event that I do encounter a flat, I want to be able to repair it and continue riding, rather than barely inflate the tube and be forced to turn around and ride home. That’s precisely the reason I chose Topeak’s Road Morph G bicycle pump. Overall, I feel this is The Best Portable Bicycle Pump one can buy!
