1. How much real world difference is there betwen Deore, LX, XT, & XTR, besides weight?
2. Look at this bike and its frame...
http://www.ibexbikes.com/Bikes/APG-LX-Details.html <- the bike
http://www.ibexbikes.com/Bikes/APG-FRM-Details.html <- its frame
The linkage is similler to specialized FSR, but the rear piviot is on the seatstay vs. the chainstay.
I understand this design is essentially a single piviot and suffers from "brake jack" is this all or are there more disadvantages of this design?
Thank you, X-Zen
