There must be a few sets of the standard rockers about that came from bikes converted to e.g. the Push rockers or later models to give 5.5" travel.
PUSH and 5.5's would be complete overkill for me, I think. I have 5.3's, but if they are all relieved like that, then I may shop for some older 5.1's
And it looks to have failed at the crest of the relieved section, relating the failure to the modification. Stress concentration at the reduced cross section and a fatigue crack propagating until the remaining ligament is overstressed and tears. The fracture surface would show this.
All 5.3 rockers have the valve clearance recess. The older 5.1" rockers which were used withe the Romic shock don't have this.
Really? that's too bad. I dig the 5.3's and I'd like a set without the indentations.
Rocker failure is pretty rare, but its also easy to pick up Spot rockers on eBay and through mtbr.
I did snag a set of 5.1's and 5.3's, from MTBR and eBay respectively. Also picked up a later rear swingarm assembly, with the asymetrical stays.
It's a nice bike. I like it.
