Roberts DogsBolx 1994


Retro Newbie
It has been 11 years since I posted a thread about my Roberts DogsBolx. The picture links have disappeared a long time ago so I thought I would create a new post with relevant updates. Back then I never entered it in the BOTM but will this time.

Custom frame, handlebar stem, front cable hanger, headset bearings and the lightest front fork available. They supplied Tange Superlights. White Pearlescent paint with Gold Clarendon graphics.
It was assembled by me in July 1994. It still has all of it’s original components (except inner brake and derailleur cables and NoS grey Specialized Umma Gumma More Exreme / S tyres as the originals have rotted away!). It was designed to be very light and as durable as possible. All the component steel nuts, bolts, spindles where possible were replaced by SRP Titanium equivalent throughout the bike. All the bearings (including the headrace) are cartridge type including the jokey wheels bearings.
