Changing the rear travel lenght

[tombre2]

if you change the rear travel of the 04 norco atomik from
6.4" to say 7.4" how much with it affect the geometry,
anybody done anything similar to their own bikes
come with say 6" and put 1.5" on or similar

cheers tom

The only to increase the travel on Norco is to incease shock stroke length. This will raise the bottom bracket & steepen the head angle. You can offset this by a) running a 24" rear wheel & b) using longer travel/taller forks.

I had a 2003 Norco Drop & fiddled around with changing travel, but IMO it is not worth it. The steering feels weird & the leverage ratio on the shock is increased, making it more likey to damage equipment. I changed from a 2" stroke to a 2.25" inch stoke & could only get 0.6" extra travel (5.5" >6.1"), at the expense of crap geometry.

6.4 inches is enough travel.
