it is time to address how to carry your pump on the Rambler. The air pump for fixing flats can be a contentious issue. Not quite as volatile as saddles an handlebars, but there are still strong feelings with regard to mini or full frame options as well as the now common CO2 cartridges. Personally I have never fallen in love with the full frame pumps, and tend towards the hybrid mini pump with a hose. These get me an acceptable inflation speed and are easy to use with close to zero chance of tearing off a valve stem.
With my bias towards this pump as well as frame bags, the long narrow bag often seen under my top tube, I decided to omit a frame pump nub on the Rambler. The nub will rapidly wear a hole in most frame bag materials. That said there are still a couple of ways to get a frame pump on your Rambler. The first is between your rear axle quick release and the seat tube weld cluster.
I have used this method in the past with great success, on and off-road. In general I would strongly recommend a velcro strap between around the pump and seat stay as a secondary bit of insurance that it does not self deploy. The other options involve old-fashioned clamp on bits. Either the once ubiquitous “umbrella holder”
