The Revolution Adventures are made by Vaude, so they inherit the excellent back plate and mounting system, very similar to that on the Discover (this one also gets an adjustable hook for stabilising on bumpy tracks).
With the inserts, clips fit a 10mm rack without any rattling but they're hard to get off - we'd recommend removing the inserts when using most standard racks, and using extra tape if needed instead.
The Adventures are a really good size for general use, effectively being roomy front panniers or compact rear ones. For the money, build quality is really good, with an appealing look, a mesh outer pocket, good reflective piping and reflective LED tabs. There's a front lid pocket and a rear one that hides away a bright yellow cape.
