Chas Roberts Custom 1990

Project in progress

A foreigner in the US Steel Fights Back group - Chas Roberts. A fantastic frame builder from UK.

This frame came to me from a German collector, who found it on eBay UK. Unfortunately there was no more info until that point.

The Robets Custom in Hamburg

History research - #51 from 1990

After some searches on know platforms,  I found this picture on Chas Roberts nice flickr Page (link) and the opptortunity to contact Chas Roberts, which at least confirmed some important things. It is a Roberts Custom from 1990, build in January and it is number 51 - always nice when the serial numbers are structured.

Request to Chas Roberts


I found your mail address on the and I´m hoping you can help me with some more details and identification on the beautiful Roberts frame set I recently bought.
The seller didn’t know much about it, only that is was sold on eBay Uk a few years ago.
First I assumed it is a white Spyder, but the missing cable routing in the back confuses me a bit.
The serial number is: 
The measures are
Top tube: 22.5“ (center-center)
Seat tube: 19.5“ (center top), 17.5“ center-tob tube
Steer: 5.5"
Is it custom frame made model? Do you know the shop: „Renovation - Bob Jackson - Leeds“ what is written on the decal at the bottom of the seat tube.
The only other information I found was this bike with V-Brakes, but I hardly can image this frame a young timer. This is taken from flickr
Thank you very much for your help.
Best regards from Germany,

Feedback from Chas Roberts



Thanks for your email.


Unfortunately, due to the way that records were kept at Roberts Cycles, we don't have access to the frame number log; we can only find details about a frame if we have the name of the person who commissioned the frame from us. If you know this, we can search the files. Without the name, we're sadly unable to help.


With the number you have, it indicates it was built in January 1990 and would have been the 51st frame to leave the workshop that month. Almost all Roberts frames were custom, particularly the MTBs - for a short while, Chas produced a series of road frames with standard sizing, and the company produced runs of similar frames for other brands for a time. Sorry not to have been more help.


Enjoy the ride!
