Triban 520 would be a lot faster than this bike, not only a lighter bike but much more efficient gearing. The only issue is the rider weight limits, about 85kg for btwin but I think Cannondale are at 136kg for rider weight. 100kg total load for btwin, 160kg total load for cannondale. Personally I'd prefer something like the Giant Rapid 3 which admittedly has a inferior groupset but a much better frame than either of these and can probably match the btwin for weight despite much higher rider weight limits. At this price level there is always some sort of compromise though. I also like the way Giant entry level bikes often get confused for much more expensive bikes due to some brilliant paint jobs on even their lower end bikes. Lastly Giant actually make their own bikes they are an actual manufacturer with their own factories rather than brand/importer.
Hmm, this or the Triban 520 Flat Bar.... So many choices!
Doesn't look bad for half price but how was that bike ever worth £850? Seems like a £250 premium just for the Cannondale name. The cheaper Quick 4 model (normally cheaper but not here becasue of the discounts) has a better spec in real terms. It will be easier up hills and faster on the flats. Off road a 1x drivetrain makes a huge amount of sense for rapid gear changes as you go over different terrain but on the road it can be a bit of a compromise. https://www.startfitness.co.uk/cannondale-2017-quick-4-mens-hybrid-bike-green-c31407m50.html
It's horses for courses Mr .... it very much depends on the type of rider you are.....experience and so on....I ride drops in London... it's a piece of cake... Unless you're a hipster, with flatbars; Hoxton beard optional.... Interestingly a lot of women (sorry if this sounds sexist) do prefer flatbars...as do beginners... or newbies to cycling...
I think flatbar is still best for commuting when you get traffic or more technical routes
