The weight is a tricky one I must admit. The Vantage off the shelf and according to Dawes, weighed just over 30lbs. I've no reason to doubt that as mine weighed a little more (can't remember the exact figure) and that was with lights and all the other crap that was on it.
This one, the 'Raleigh' with lights, dyno hub, gps, full mudflaps and guards but also with lighter stem, bars, seatpost wheels yadda yadda yadda etc weighs a shade over 32lbs. There's probably not much in it to be honest. However...The ride!
Wooooooo it's soooooooooooooooooooo smoooooooooooooth
I needed a Zoom suspension seatpost on the Vantage. Needed it! Not so with the Raleigh. Granted, a steel tube doesn't quite have the same shock absorbing qualities as a spring, but there is definitely less of a sting over rough roads and trails with this over the Vantage.
The steering isn't quite as lively as the Vantage and that's a good thing. Believe you me! I could never relax on rides with the Dawes and whilst the handling on the new build is still quite sharp, it isn't the "Oh shit I better not turn too hard incase it folds up and kills me" kind of sharp as the Vantage. I feel I can make tighter turns but more smoothly so.
The Raleigh has a shorter wheelbase (10mm or so shorter) and shorter chainstays (again by about 10mm) and I do feel that climbing is easier.
Overall I'd say it's a nicer bike to ride. Not because of any one particular thing, but little subtle differences here and there that all mount up.
Things that really wound me up though are the lack of planning for what is a touring frame and fork. No mounts on the fork for a rack. None. nadda. That's just stupid.
Top tube routed cables. That meant a silly expensive pulley to use a road mech with a road chainset. Again, stupid. No bottle cage mount under the down tube. And best of all, no brake hanger for the rear brake. That meant an aftermarket bolt on jobbie that flexes a lot and makes the cantis a bit too spongy.
But for a frame and fork that cost £140, it's bloody good
