the old one is quite a lot different to the new one half an inch less travel and the back end has been re-designed to get rid of tyre clearance issues. plus new cable routing which is weird but neat and does away with a lot of cable rub. think the paint has been improved too.
I do work at Crosstrax, like I said I'm totally biased, but I have a pretty impressive array of bikes that I could have as my own and Ive been a Yetifan for years, still love the 575, I think the Zesty is the best all-rounder there is, but for me its the covert, which is why I own one.
But I'm on here bigging up my personal bike just like any other member does.
brake jack – not really a problem on the Transition as it only really affects Lawwill designed bikes, maybe hei hei is confusing it with brake squat which affects all bikes, including DW designs but to a lesser extent, but then as DW himself agrees brake squat is a good thing as when you hit the back brake the bike balances itself a little by sitting into its travel and stabilising the bike.
Still its my opinion that's all.
