I'm a bit confused, is that an arm twist?
Ah, the old Schrader versus Presta problem. It gets even the best of us, and sometimes you can even have the wrong kind of pump. I’ve thrown a shoe a couple of times and had well meaning people try to fit me with the wrong size and some things just don’t work.Thwarted at 18 this past weekend Skipper. Might be a rainy this coming weekend. I think I am back in the trouble zone for this ride.
So as I have mentioned before, I took the tandem down to a local bike shop to have it tuned up back in February as it has just been sitting for the past ten years. I usually keep two brand new tubes in the seat packs that fit under each seat on the tandem, so one tube per seat pack. The tubes that I had in the packs had dry rotted when I took the tandem in for the tune up so when I picked the tandem up after being worked on I asked for two new tubes to replace the old ones. The guy in the bike shop handed me two boxes with tubes and rang me up for the tune up and the tubes. As soon as I got home, I took the tubes out of their boxes and placed one in each seat pack.
So fast forward to last Sunday. After getting the flat, I took the wheel off the bike, removed the tire and took the tube out, I then pulled out one of the new tubes and unfurled it and when I got to the end and the valve stem appeared my heart sank. The guy in the bike shop had sold me two tubes with schrader valve instead of a presta valve which the tandem takes. I hadn't taken the time, when I replaced the tubes in the seat packs, to read the box the tube came in to realize that it was the wrong valve. The new tubes are folded in such a way that the valve is hidden from you until the tube is completely unfurled, which I didn't do either. Hopefully, I won't be making that mistake again. Once I got home and checked out the flat, it appears the valve stem was the culprit. I exchanged the schrader tubes for presta ones yesterday after work.
