As I posted the other day, Little Nellie, my Bike Friday New World Tourist, was in the shop for a new chain and new bar tape. I also needed some help getting a tire mounted on the front rim. When I left the bike the folks at Spokes Etc. told me that they’d have the bike back to me on Thursday.
Imagine my delight when I received an email telling me the bike was ready today. Yay!.
Imagine my befuddlement when they also told me that the front tire was flat.
What a weird email.
I tried and trued to get the tire on. It was a new Schwalbe Marathon and the Alex rims on my bike are unusually tall. The combination makes mounting tires extremely difficult. It is never a good idea to use tire levers to get the tire on because you stand a very good chance of puncturing the tube.
After over an hour of frustration and quite a lot of lost skin, I resorted to my metal tire levers to no avail. So I took the bike to Spokes and waved a white flag. Carlos tried to get the tire on and couldn’t do it so he pulled out some thin plastic levers and popped the tire on. He then pumped it up and rolled the bike into their repair queue.
So, long story short, we don’t know who punctured the tube. Wanting to get the thing fixed today, I told them to go ahead and put a new tube in. After all, I still don’t have any skin on my thumbs.
When I picked the bike up, Carl had just finished mounting the tire. With his bare hands. I asked, “How did you do this?” He explained that he pushed the wire bead of the tire into the well of the rim and, in short order, he had the tire on.
Carl’s secret is that he has tons of experience dealing with Bike Fridays and recumbents. He’s dealt with this problem scores of times. In point of fact, I tried to do what he did and I just couldn’t get the tire on.
While he had my bike, he looked it over and told me about all sorts of issues the bike has or will soon have. The rear derailer is on its last legs. He recommended a different derailer, one for mountain bikes (Deore) instead of road bikes (105), because, unlike the road derailer, the mountain bike derailer is designed to work with a wide range of gears such as Little Nellie has. He also pointed out that the cable feeding the derailer had been installed incorrectly with a zip tie. This interfered with the proper operation of the derailer. He removed the zip tie and set things right. He then pointed out that the indexing on my rear derailer shifter was about to die. This is no big deal because with a twist of a nut the shifter will work just fine in friction mode. Finally, he told me that the long cable housings on folding bikes trap water and that the next time I have work done on my bike, it would be a good idea to replace the cables and housings.
Bike Fridays are odd ducks. So are Tour Easy recumbents which have similar cable and housing issues. I consider myself pretty lucky to have Carl working just three miles from my house.
For those of you thinking that this tire mounting thing is peculiar, check out this video that describes the trick Carl used.
Much thanks to Carl for showing me the ins and outs of the drive train on my nearly 8-year old bike. Next winter, I’ll take it in for some of the work Carl recommends.
