I am on my third Infinity link in 18 months, each replaced under warranty through my LBS. The grease ports just don’t really work as you try and pump grease through a small hole that actually butts right up to the kashima stanchion so the force required to get it to seep around is too great and I find it just comes back out at me!
The suspension performance is absolutely awesome but, the whole link just isn’t sealed well enough to cope with Scottish/UK grit, grime, mud and the inevitable washing. My previous two links when taken apart after 3-4 months have had large patches of no kashima coating left on them and the bearings seized. The remedy is easy, to take the link out once a month, give it a good clean and regrease but, that requires a bit of mechanical confidence and the whole link area must be spotless and torqued correctly when putting it back together so that the alignment of the rails and link are spot on. Any deviation can create tiny gaps in the seal allowing more grit into the link etc. And at £270 for a new link, once the warranty period (2 years on the link) runs out, it could be an expensive bill every few months if not regularly maintained. I wrote to Yeti/Fox asking what their R&D departments are doing to make the link more robust for anywhere else but the Colorado dust but not had a response.
Best bike and suspension performance I have ever ridden, but needs TLC. As the whole bike is based around that link, if it’s not working at full awesomeness the whole ride is affected.
