Contact HaulBikes.com I think you should call. If I remember its 1-800 haulbikes.
From Canyon City take hwy 50 thru Salida then you make a choice to go South or West South will take you over Wolf Creek Pass a very nice hwy to Durango, or go West at Salida staying on hwy 50 thru Gunnison to, Montrose then South on hwy 550 to Ridgway, Ouray, Silverton, the "Million Dollar Hi way" into Durango on 550. If you have never been on hwy 550 it is a must do road. Remember rain gear it can be very nice that time of year but at that altitude it can always rain maybe even a snow shower no big deal. Take lots of pictures and breath deep there is a sign at the top of one of the passes that says this is some of the cleanest air in the world. I don't know about that, but it is a real treat to ride area!!! From Durango your choices are limited and you make the Canyon South rim in one day. I recomend the North rim a lot less people much more intimate and a 1,000 foot higher. The south rim has a better angle with the sun at your back for most of the day. Either way it is a Breath taking view.!!!!
Have Fun
