The "XLBird" Passes Testing

 I was text messaging with Ari Andonopoulos last week concerning a rear brake issue with my XL Singular Peregrine Mk4. The mount had gotten painted and it needed facing and we were discussing options to get that done without spending hundreds on a disc brake facing tool. During the conversation Ari referred to the bike as the "XLBird". 

That stuck with me. 

So going forward the XLBird name will be attached to this Peregrine Mk4. I don't make the rules folks. When someone gives you a nick-name, that's it. 

Oh....so about that brake, I ended up doing some very careful, tedious hand filing with a steel file I have and it solved the problem. No more rear brake drag. That and a loose headset were the only two gremlins I had to battle after the initial build of the bike. I did my traditional grave yard test and then a wider ranged neighborhood test ride before these adjustments. 


 Once the initial short range test rides were done, and the rear brake was figured out, I decided I could range out a bit further afield and I did an hour long ride out to the Harold Getty Lake paths. I took alleys back home too. The bike was excellent. No mechanical issues at all. 


 The post previous to this concerning this bike had a comment saying that this bike looked long. It is definitely longer than the size Large Peregrine. You can feel it when you are riding as well. The frame and fork feel like a giant spring at times. The Large Peregrine was much stiffer in this regard. 

Handling was very stable, I thought. Right after a fast downhill I hit some rutted up dirt. The bike pitched sideways but due to the stability of the front end I was easily able to catch the bike, keep it going straight, and out of the rut. Steering around tighter corners was good. Not that this bike will see a lot of single track, but it is nice to understand the bike will carve a corner if I need to do this. 

No rattles, no misshifts, brakes worked, and everything felt good. Now I may have to dig up a silver post and maybe a saddle. Then this bike is good to go. I'm very happy with the outcome of the switch to the XL frame.
