I was really stoked to try out a new 4.8″ Lou on my 2012 Mukluk 2.
However, after a test fit, not all is well in the world. The center lugs on the Lou hit the yoke between the chainstays on the Muk at 10psi. At 15psi, the lugs completely lock-up on the yoke. They’ll clear at 7psi or less…right now (but I’m advised that they grow significantly over a couple of weeks at pressure). This is using 82mm Holy Rolling Darryls.
Pretty wide on 82mm Rolling Darryls.
Even with my modified cassette, the bottom 1/2 of the cassette is useless in the smallest chainring.
The middle chainring clears, no problem.
This is 10psi:
It makes the Big Fat Larry up front look TINY.
This is the clearance at 5psi:
Buh-hmmer. Back to Husker Düs?
UPDATE: I left them at 25 psi overnight. The next morning, they didn’t fit at all. Not at all. Not even at 4psi. The amount they stretched was HUUUUUUGE. It’s a no-go.
