30mm= 30 millimetresI suspect that “30Mn. YMMV” probably means something to those in the know?
YMMV= your milage may vary
On the by, "milage" must be CC lingo, my spellchecker keeps beeping

Sliding forwards when riding is a bike- fit problem.I have inferred, given the age of the bike, that the OP knows what he's doing and the slipperiness of the saddle is a result of many years of riding - i.e. can't be mitigated by altering the fit.
To be perfectly correct it should be mm, not Mm - a Mm is a thousand km!If quoting, please quote correctly, as I have no idea what an "Mn" is. And Pat, it's Mm, not mm!![]()
That's right... 30,000 km!Read my post @ColinJ : "My '74 Competition started pulling away at the rivets after, maybe, 30Mm [or riding]."
Angle looks ok but it looks quite a long way forward, I’d move backwards 10mm. Your weight must have come too far forward. It might also be a tad too low but you would need to experiment a bi
Thanks geocycle. Think you have a good point with my weight coming forward. Will try saddle a tad back. Cheers.Angle looks ok but it looks quite a long way forward, I’d move backwards 10mm.

Thanks Peter. I agree. Think geocycle has a good point regarding where my weight is on the saddle. Looking into this.I have inferred, given the age of the bike, that the OP knows what he's doing and the slipperiness of the saddle is a result of many years of riding - i.e. can't be mitigated by altering the fit.
You are by no means alone in adpting this 'system'I have a good system for getting on/off which works very well for me (leaning the bike towards me)
