Saw this on your first post... 👍

Touches like the middleburn oiler on the rear brake cable doubling as a frame protector, and the colour matched cable hanger.

Nice garden too!
 
G O R G E O U S ! ! ! 😍

Love a good tech sheet with breakdown of specs including overall weight in kg and lbs!

Nice subtle additions/deviations to a standard build 👍😎

Bike is lovely and so too is your garden. Nice to see some uncut lawn and box hedges that haven’t been devoured by the box moth caterpillar like ours!

Love the colour choice and older style Roberts decals - I rode a later more scruffy DBlx for awhile loved the ride , but not the stickers! very shallow I know ... what are the forks ? suprised not to see the rare matching Roberts ‘fork play‘ included?

I asked Roberts to supply the lightest forks available with curved blades. They chose Tange superlight mountain bike forks. Tange’s lightest rigid fork had butted chromoly blades and very strong investment cast dropouts.
 
Nice! really like the look of the build … now intruiged by the white horse decal… a dedicated Ridegway rider? is the chalk theme in the paintwork?

I had Pace RC30s on mine - which gave a good ‘direct,‘ ride and suited the geo.
