Just another for discussion – why do the altitudes have under-downtube cable routing? What a stupid thing for an alleged ‘British specific’ bike!
The 2007-model Altitudes have top-tube cable routing, but the 2008 and 2009 ones have it along the down-tube. Cables on my 2008 Altitude work just as well as my wife’s 2007 model, don’t see any problem with it.
Downtube routing: less sections of outer cable (2 vs 3), slightly shorter cable run, where the cable enters the rear-most cable run is more protected being on the chainstay and not the seatstay. Doesn’t interfere with a crud catcher either. What’s not to like?
