These blend seamlessly into my bike frame, and while very easy to install, they were sold not quite as pictured.
The ones I received had a threadlock nut already installed on one end of the threaded bolt as it would sit on the frame of the bike.
The original is a single long bolt, and as such locked on the left, with only the right open, for you to lock down with the supplied nut.
This is fine in a sense as it's emulating the original bolt you remove. The problem is, you have to chase that original bolt out, which means you can't do that from the right side and
also then end up with the locking bolt on the left. You only have the right side bolt open to chase with, so the left side ends up on the right, which means the left frame slider would then end up on the right (which doesn't fit into the frame hole).
Unless you have an extra bolt to first chase the original out, and then chase that holding bolt out again with the frame-slider one starting from the left side of the bike, you will have to have the locking side on the right, and because you have to install with one frame slider on the bar (because one end is closed off with this configuration instead of an open threaded bar you then add sliders to each side at the end), you will also have to swap the left/right configuration of sliders on the bar as it is shipped to you, as they only fit one way into the frame holes.
I'm not sure if this reads back a little over-complexly, but sliders are marked clearly, left and right so once you have them in your hands, it's easy to figure out how to correct the little issue.
It isn't a big deal, but if absolute accuracy of original specs are your thing, it does kind of rub you the wrong way, as someone meant well in changing the original specifications of a threaded open bar both ends, to installing that threadlock nut, I imagine to prevent poor installs, where nuts were only narrowly threaded.
It doesn't seem to matter, as there's no mounting hardware that sits in the frame with this design. The whole slider does, which is heavily reinforced on the inside with a steel collar that is set into the slider, and the only washers are inside of the sliders, so even with this needed flip over, it's fine.
So yay, but boo.. Had I known, I would have likely purchase a holding bolt, because I'm weird that way, trying to keep things super spec perfect.
Yes I would buy again. They are subtle, a good price and yet still perfectly adequate quality.
