Maybe I am not being as clear as I could be? Even bouncy "spring in a tube" suspension can be of use on very uneven roads, towpaths, cobbles etc but absolutely useless on a metalled road or steep climbs if you want efficiency and control.
Yes clear I understand where you are coming from but I disagree with your analysis.
I have very little experience as yet but the way I see it (subjectively) is:
- I am climbing sitting down using full assistance not standing up on the pedals and trying to beat the record on the Alp d'Huez.
- The only suspension movement I have felt so far was bumps being absorbed never pedal movement pumping.
- braking should be more efficient with suspension??? I haven't been able to lift the rear wheel yet in front brake testing.
I am coming from a steel frame/fork 26" bike to an aluminium frame front suspended 28" wheel bike. Already the bigger wheels wipe out much of the vibration. Adding baloon tyres and front suspension I have everything to learn about how this bike handles in all conditions. For the moment the front suspension gets two thumbs up. I haven't been able to weigh the bike yet (who stole the scales?) but I feel that I must be close to the 20.5 kg of the old one, maybe 22.5 kg and those 2 extra kg are in the front.
