I bought a granite chief from them about 18 months ago. Very happy with it. As a company they were good to deal with – the UK rep met me at Swinley and I had about a 2 hr test ride. the configurator thing is cool too.
Compared to my mates Canyon the Rose seems much better put together – I think because they are assembled by ze Germans, whereas I think the Canyons are assembled in the far east. Difficult to qualify that – but my mates brakes needed bleeding after a few months, cables tightening etc….. whereas the Rose was tight as a drum for aaaaaaages. We both ordered at the same time, mine took longer to come (about 6 weeks), but I hear canyons are taking that long now anyway.
I think that Canyons have got the edge on vfm these days (in terms of components), but there have been a few threads on here about quality issues recently, and less-than-marvelous customer service.
The only thing that annoys me about my Granite Chief is the stupid chuffing Pressfit bottom bracket plastic adapter doo-dah. BUT, this does allow for a downtube the diameter of a beercan – and having broken a couple of frames, I wanted something made of girders.
Hope that helps?
