Appalache Real
Table of contents:
FRAME OVERVIEW
After Balfa brand had gone to UK, the original Balfa philosophy stayed in Canada, where Jerome Roy (Balfa co-founder) prepared the successor of Balfa BB7 under new name - Appalache Cycles
The Real utilises all unique Balfa's idea and solutions (see "BB7 Frame overview" for details):
- High pivot suspension design with chain pulley;
- "Parallel trajectory" axle path;
- Aluminum front, Cr-Mo swingarm.
But it is also:
- Lighter - 9.5 lbs (4320 g) with FOX DHX with titanium spring;
- Lower bottom bracket, lower top tube;
- Shorter chainstay and wheelbase.
- A bit simplier - less complicated swingarm links and pulley location
THE DIFFERENCE
As users and reviews report, the Real maintains BB7's advantages due to similar high pivot suspension design - the frame still maintain momentum over rough impacts and has stable wheel base. However, weakest points of old design were improved - frame is lighter, shorter and lower, therefore it can be much more agile and nimble at low speeds, while still being stable at high speed.
So, you may ask, is this bike better, than BB7? Yes, it is.
