finally... pelican-edition:

Rear disc brake removed (as unnecessary).

i once thought like you...in normal riding conditions the front should be sufficient to stop quickly. in emergency situations however a rear brake can be the difference between an accident and riding away untouched. i still agree that i use my front 90% of the time.

Ivan,
Awesome group riding. What is happening that there are no cars and you have the roads alone? It seems like a dream come true.

 

[ivanovlev]

The whole circle was closed as part of the bicycle race "Five Rings" (internal side). Only bikes had access to circle (external side). We looked like a bicycle, so ...

I'm looking at your bikes, and I do not see in any of the fenders. How do you drive in this weather?

standart SKS wing's

they usually called fenders

 

[jansevr]

very cool! i like the idea for the "wings." they look better than the original in my opinion and i'm sure they're strong as hell now too! i might have to do something similar in the future. finding "wings" that are over 2 inches is difficult.
