Mine is a retro 70’s/80’s 531c Poyner with Mavic GP4 rims, Airlite radially spoked front hub and 165mm cranks. Not strictly Manchester-proof as the BB is 27 not 28cm. Sorry piccy linky not worky today.
Having ridden this at a three hour session at Newport last weekend, and their stock Dolan pre cursa, I can safely say I won’t be upgrading to the Dolan. The 73 degree head angle made it feel like a tank on the steep boards (Poyner is 74 degrees), the transmission sounded awful (mine is silent) and the weight excessive. I’m sure their much nicer bikes are just that, but the pre cursa was just not to my taste. I paid £125 for it about 15 years ago. Started track riding last year, but it had been out on the road quite a few times.
By contrast, the pre cursa geometry is identical to my Paddy Waggon, and on the road, that bike handles fantastically well. So it is horses for courses. I would, however warn against proper track gemetry for road bikes because there are many better alternatives now.
