Re: Another Cyclist Dead... Suspicious Circumstances

Looking at the map it appears to be on the lower reaches of a well know cycling route away from the main road over the Clwydian hills between Mold and Ruthin. More here about route http://100hillsforgeorge.blogspot.co.uk/2012/03/hill-no-93-88-penbarra.html Pure conjecture on my part but if heading u...

Re: Frame geometry question - one for a frame builder ?

Just to update anyone interested as to my discussions with my frame builder. He agreed that he had made an error and immediately offered me a full refund on the frame. Rather than take this route and in view of his honesty (anyone can have a bad day) I have agreed that he can modify the frame at his...

Re: Frame geometry question - one for a frame builder ?

Andy Thank you very much for going to the trouble to manipulate those images. A picture (combined) tells a thousand words! Colin Just to add final bits to the jigsaw. Chainstay lengths Old frame 42cm New frame 40.5cm Front Centres Old frame 58.5cm New frame 63cm Should be an interesting conversation...

Re: Frame geometry question - one for a frame builder ?

Thanks for all your comments and thoughts .... Whilst pictures cannot show sizing of the frames for those interested they can be viewed here https://skydrive.live.com/?cid=0E0F344CF39CA060&id=E0F344CF39CA060!113 Raleigh (blue) is obviously original frame. Note new frame has oversized tubing. Reg...

Re: Frame geometry question - one for a frame builder ?

Yes both are what might be considered as traditional lugged frames with horizontal top tubes. First one was built by Raleigh's specialist lightweight division circa 1986 (Gerald O'Donovan at SBDU - more here http://www.classiclightweights.co.uk/builders/raleigh-sbdu-builders.html ) I have been happi...

Re: Frame geometry question - one for a frame builder ?

Updated figures for top tube length - now properly measured as per advice kindly given

Old frame = 58cm
New frame = 65cm

So new frame my "stretch" to bars would appear to be 65 + 12 = 77cm as against 58 + 10.5 = 68.5 cm (second figure stem length)

Regards

Alan

Re: Frame geometry question - one for a frame builder ?

So from centre of where seat pillar resides to centre point of fork column ?

.... Accepting this will be a rough measure but possibly more accurate than my original.

Re: Frame geometry question - one for a frame builder ?

I seem to be causing confusion by talking about a top tube length of 54 cm .... I did say in my original post that my measurement as to this might not be correct but as I was using the same methodology it should not matter as I was comparing like with like. However it is quite apparent that this is ...

Re: Frame geometry question - one for a frame builder ?

Frame geometry question - one for a frame builder ?

I am looking for some advice as regards frame geometry and my new frame as something appears odd. Scenario thus - sorry it's a bit of a novel ... I approached a local frame builder to build me a bespoke 853 steel frame based on my existing (25 year old) bespoke 531c frame. This old frame is what mig...
