Blackburn Mammoth pump

Verified Buyer Reviewed by Colin from RI on Monday, August 29, 2016
I received this pump just over a week ago and it has already paid for itself as part of my mountain biking kit. It's been used used to inflate a few trailside repairs of mine and riding partners. The high and low pressure option works well and it is quite light for what it provides. The only issue is with the "lock/unlock" indicator. Once the pump is on the valve, it must be twisted to lock onto the valve. The indicator is reversed. This is a $40-$50 pump so the price is right
