I was little sceptic at 1st before ordering but after using it, I m satisfied. Nice product and works almost 95% of the times.
I’m using it on my Trek Checkpoint ALR4. It’s a gravel bike.
i bought this product,but i am unable to use it as it doesn’t fit on my BMC SLR bike .so i suggest riders to check their bike frame and the ass saver compatibility before ordering.
