Best soft roll-up tonneau cover for cargo management system

Most of the soft roll-up covers I've seen look like they require removing the cargo management rails. The truxedo lo pro qt is the only one I've found that mentions these rails. Does it allow the use of the rails? Is it the only good option for a soft roll-up if I want to use rails?

I used a trifold on my last truck which I liked, but I had to remove it to carry a bike with a fork mount on the front rail. I've thinking a roll up will work better for carrying bikes.

 

Or you could put it on top

 

The Access roll-up cover works with rails. In fact, I think it uses the rails to attach the framework. New truck I just picked up on Monday, so I haven't even had it rolled up yet, so I'm not sure how it attaches, but when I bought it, the dealer said they had one in stock if I had a Tundra with the rails, but would have to order if my truck did not have rails.

 

You can still use the rails on the Truxedo X15. Tiedowns/accessories are limited in adjustability between the tonneau clamps. I’ve gotten a bunch of compliments on it. It is basically convertible top material. The wrinkles in this pic were gone a few days after install.

 

I have the same but my model goes over the rails and held on by strong velcro. Rolls up to with in 10 inches to the cab. The only water gets in from a car wash and that enters thru the sides of the tail gate.

 

X2 on the Access, I have the Access Lorado on my CM. There are 4 clamps on each side, and they clamp directly to the rail, so you just can't slide the tie-downs forward and back all the way. I ended up putting my low-profile rings in the rail around the middle of the bed while I was installing the clamps, and I put the large tie-downs on the cab rail. Works well enough, I can still slide the rings back and forth between the clamps.

 

I agree with polymerhead I put pro x15 from Truxedo and love it,the new fabric is awesome.
