My Revelo Thinstem for 25.4mm handle bar is a well built stem that does its purpose of reducing the footprint occupied by my bike. I ordered it for my Change DF-702 folding commuter bike. Bob Forgrave from Flatbike Inc, even emailed me to make sure that I'm getting the correct size. It took 2 weeks delivery time from US to Singapore which is expected, via USPS. It came nicely packed with installation instructions. With the stem installed, it adds a little over an inch to your handle bar riding position which to me is barely noticeable. One issue that I am facing is, because the handle bar is now a bit higher, my rear derailleur cable is over stretched when folded. This is because my bike was supplied with just enough cable slack so as not to interfere when folded. I guess I would just have to replace my cable to solve this. Other than that, I am happy with the purchase, and would recommend this to friends and other people who want to reduce the space occupied by their bikes when parked. Of course this is not for weight weenies because it will certainly add a few grams to your bike. It's a matter of choosing the right product for the intended purpose. For me, it certainly satisfied my requirement therefore happy with it. How I wish I could post before and after photos of my bike after installing the Revelo Thinstem but this review space does not have the option. Highly recommended product, highly recommended supplier.
