I have an older 2 position hitch rack that has the wheel cradle and j-hook to secure the front tire. It was made before the 29-ers were getting popular and the j-hook barely fits over the front tire. It take a lot of wiggling and pulling to get it over the top and only has a 1-2 clicks when pulling it down to lock it on the tire.
So while it works, I was wondering if I could by replacement arms for the rack so it would hold the 29-er's easier?
