Bob Jackson Renovation

The Bob Jackson project was started some time ago when the frame was rescued from a skip and given to us, see original pictures.  The late 70's Early 80's Nuovo Olympus with Prugnat Professional lugs and Campagnolo dropouts was deserving of referential treatment while remaining practical.  So it was off to Argos Racing Cycles in Bristol who did a fantastic paint job using Monaco Blue with Perl White combination with French bands on the seat tube.

We have been keen on hub gears as a practical option for some time as it gives a clean fixie look while providing a range of gears.  A 5 speed Sturmey Archer hub was selected as a trade off between weight and gear range.  We built the wheels using Rigida Chinra 700C rims and Stainless Steel spokes.  The front hub is a Campagnolo Record large flange which is probably they type of hub that this frame was equipped with when it was built by Bob Jackson

The Chainset is an FSA Gimondi with 48T chainring.  This is coupled with a 21T sprocket on the rear hub to provide a low gear and also allow the hub to fit neatly inside the dropouts.
The Bottom bracket is Campagnolo Chorus while the headset is provided by BBB.
The RX600 Brakes are coupled to Modulo brake levers mounted on Lauterwasser handlebars.
The Cinelli stem needed to be shimmed as it was a pre 1994 model.  
The Brooks Champion Special B17 is a must and is mounted on an SR fluted pin.
The result is a 25" bike that is just over 10kg. It's a smooth gliding ride which is responsive on the hills
