Another (and definitely not the last) frame that has to go!
Can be collected in Ayr or Glasgow
Happy to post at cost/insurance
Ask away for anything and thanks. T

TT58ctc
ST 61ctc 62.5ctt
HT 20cm
Beautiful metallic dark blue Roberts colour with Sigma decals (Roberts built quite a few bikes for Sigma racing etc)
Fully pantographed Roberts seatstays. Roberts Columbus panto’d rear dropouts.
1" threaded steerer
No dents, cracks, etc. Some very light superficial rust to the bottom of the HT but easy enough to sort and definitely not structural.
Very light tubing so most likely Columbus with high end Reynolds as was his trademark

£350..300

Thanks. T

I had the CX version of this and it was a beauty to ride.

I remember, I was so close to buying it from you! Many thanks, I have so many bikes on the loft though that something has to go! T

Would love to see some pix of this. I have a Roberts Sigma frame in Columbus EL-OS. It is a spectacular ride!

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
