I bought the 1-UP this summer and have absolutely no regrets. Easy to install. I first took short trips first with the roadie- had great fears that my bike would fall off because it was so easy to put on. Spent a lot of time checking the rearview mirror Travelled to Tremblant from Toronto. Bike made it unscathed. Then another long 8 hour road trip back to Ontario. Windy weather. Bike is still intact. Took rack off for the winter- again - pretty easy. I will buy the add on for travelling with 2 bikes. Love this rack!
