thanks for ther input
I appreciate the input, been researching racks, i found the yakama holder 2 rack to be perfect, yes they are pricy. my local bike shop set one up and tested my bike on it. it has a build in lock cable that hides in the front wheel lock down boom, it fold up when not in use. I picked this unit since i do not have to remove my back tire. i when to 25c tires so i have to defalte the tire partially to remove and install on the bike. although my rims are quick disconnect i feel te less i have to remove install the less wear on the components and frame
