Challenge Eroica: Tight!

…and I don’t mean “tight” in the positive sense.

Last night I attempted to mount a set of 30 mm Challenge Eroica tires on my new cross bike (which isn’t actually intended for cross, but more about that later). They were so tight that I couldn’t even stuff a tube under them. So for 2 hours of effort all I got were some blistered thumbs and a popped tube (Exhibit A).

Tubular Thumb

I’ve never had a set of tires that were so tight that I couldn’t mount them. Even Veloflex tires, which are ordinarily quite tight. In this case, I couldn’t even use a tire jack because I couldn’t get the tube in. It was so bad that even Winston was disgusted. Exhibit B shows a typical feline reaction to Challenge Eroica tires.

In any case, I’m returning these and getting some of the new Grand Bois Extra Legere 32s: 230 grams for a 32 mm tire (and 181 grams for the 23–lighter than Veloflex)! I’ve used the Grand Bois 23s, 32s, and 42s in the past, and they were great tires.

Now, I just need to track down some 28-32 mm latex tubes. Every place I’ve checked seems to be sold out. Anyone know of a source?

I’ll let you know how the Grand Bois tires work out after some serious gravel road abuse.

*The blistered thumb in Exhibit A is actually from removing a too well-glued tubular tire a few months ago, but serves as an example of what you can look forward to if you try to mount Eroicas.
