Got the 28T narrow-wide in the mail yesterday so I put it on and took off the old broken big ring, as well as front shifter/derailleur.
Found my crank puller was still loaned out to a friend (who just went on a monthlong vacation), so I couldn't pull the crank and get the old granny off. Rode around the parking lot a little with the 22T rattling around on the bottom bracket.
Narrow-wide is noisy! It clicks whenever the wide links pop off the wide teeth.
