No, it is still riding along at 20 to 26 mph each and every day. I just scored some Shimano RSX Shifters for the Denali. Got them off ebay. They are still in the box they came in from Shimano. Never ben installed on a bike. So in a week or so, when I get them, I'll have them on the Denali. Now I just need a RSX rear Derailleur to match the shifters. Looking at one on ebay for 17.95 right now.

As for the Denali I have only had two flats and no problems out of it once I got the Shifters dail in. I don't like the rear Derailleur that much. becase of the slow down shifts so I am going to replace it soon.
