RR5. Same as mine was when I first bought it. The RR4 has different colour schemes. Mine's been through a few changes of clothes over the years since this was taken a few years ago.
Gringo make sure you go +2 on the rear sprocket as the4/5 came with 40t standard where the 6/7 42t or you will be finding you still miss your old one
Will +2 teeth on the rear make a big difference on the acceleration? I've got a 42t rear in my shed somewhere may well bolt it on this winter.
wont make a "big" difference,but will make a differnce.if you want a big difference,drop a tooth on the front,and +2 on the rear.
