Yes, and for many reasons. You might feel more comfortable using a specific bike pump with one bike while it feels average with another. And the bulkiness of one bike pump might even interfere with riding on another bike, yet on the primary bike, it is fine. These key differences point to bike pumps being great when they are picked out for specific bikes. That is why if you have the same bike as your friend, their recommendations for pumps will align much better than if you had a completely different model of bike. Prices are usually low for the pump, so having a specific one for each bike along with a backup still won’t cost you a lot of money.
