Brand loyalty or what?
Are all those steel hybrids?
Bought new or second-hand?
I almost bought a Discovery roundabout the time of your first two purchases - but fell in with Ridgebacks of a slightly older vintage. And am well pleased.
No, aluminium, the 501 also has carbon forks.
The 201 was second hand and the bike that got me properly started after several false starts with MTB's & tourers, it was stolen.
I have had loads of hybrids pass through from a lot of different brands, but the 501 is my favourite bike, it suited me from day one and after it's planned spring re-furb it'll go across Spain again, making it's hat trick of trans Iberian trips. I can get on that bike and ride all day
and have fun.
I have a steel Ridgeback from the late 90's (I think) it's like new now and I like that bike too.
