Heres one for you.

I own a Batavus Champion with the original shimono 8 group set brought into todays interactive cycling world on Cyclops Fluid 2 rollers for Rouvy.com use complete with Vittoria Zaffira Pro rear tyre with Continental S Innner and Ant+ dongle coupled with garmin cadence crank and rerar hub strap on with app.

By far the most economical way to do your indoor training and on a bike thats rock solid build quality shines bright with no swinging arm sway even under those last km sprints.

My endurance road bike is a Specialized S Works Roubaix but I prefer to crank out indoors on my Batavus because its so rock solid and gives you better pedal discipline to push harder.

Bravo Batavus - a truely vastly under valued racing retro brand.

Soory - cant post a photo - some stupid rule about 10 posts.
