The flexing sounds fine, no issue.

Mine failed by the "ears" on the seat stays cracking after 25 years or so use.


Now that is very reassuring. The seat stays look fine. thanks!

The 708 is noticeably stiffer when riding out of the saddle and firmer on bumps than any 531 or 753 frame I have ridden and would be my choice if I were loading up where the additional weight would would probably offset the firmer ‘spring’ :oops:


Thanks Peetee and nice to hear from a Nigel zfean owner.

your frame flexes back each time i take it? it's not just gradually distorting in one direction?

Yes Bruce, it springs back just the same and the flex is about the same amount on either side. I think it is simply a characteristic of the 531 tubing.

My test goes;
Stand next to the bike, one hand on the stem, other hand on the saddle. Pull one towards you, push other one away. Reverse, repeat.
Same starting position, but put toe of one foot on crank/BB axle end, and push.


I've just tried the above test and to be honest, it puts things into perspective, there's hardly any movement. Compare this with when the handlebars are resting on a wall and the rear end is unsupported, it seems to show the frame is essentially sound.

I do have a couple of mates with whom I ride regularly. One rides a steel Condor gravel bike. I'll ask if we can do a comparison before we go out on Monday.

Definitely won't be taking the hacksaw/ angle grinder to Nige any time soon!

Still pleased to say it springs back Brucey, even if you didn't ask the question! :)
To be honest I'm feeling a lot happier about the whole thing except for the top tube height being too high for me. I think in view of the bike shortage thanks to/due to the upsurge in cycling's popularity, I will bide my time in the quest for a new or good secondhand bike for the time being. Nigel still has a lot to offer.....
