I've been using this SixSixOne chest rig for a few years now....totally love it for the lightweight yet stout protection it provides....BUT it just kills my neck and almost prevents you from standing up and riding uphill. The spine pads ride up too high on your neck and bunch up against the rear of your helmet. Basically makes you have to force your head to look upwards. On long rides this is horribly fatiguing and happens even with a backpack full of water weighing it down. Definitely a design problem... Here are a few crappy phone pics of the model I'm talking about: I'd like to get something new for this season, just not sure if there's a product out there I might be missing. I really want spine and shoulder protection....chest/roost isn't a big deal but would be nice to have. I'm no opposed to a suit that had attached elbow guards and I usually like to wear my prot gear underneath... Looks like 661 has redesigned some of their spine guard designs....any idea if they are a little less obtrusive now? Suggestions? Thanks!
