I guess that Shimano don't offer a 36t chain ring as the inner of a double,
allowing the 50T outer to be locked off?I thought 52/36 was all the go with the hipster-roadies these days. Which cranks do you have? Should be pretty easy to get a 36 for either 110mm 5-bolt or the new 6800/9000 pattern, Shimano do a 36T for 4-bolt 110mm and there are millions of possibilities in 5-bolt 110mm, since it actually is one of the few genuine standards in cycling gear.

Please pardon my error upthread,
the groupset is
Ultegra 11 speed, 50/34,
with as far as I can see just the four bolting points,
So,
http://www.rosebikes.co.uk/article/shimano-ultegra-fc-6800-chainring-713812/aid:713814would do, (realise the posrage is almost as much as the chain ring,
just happened to have a tab open on the Rose bikes webpage) -
Looking for the (supposedly) simplest solution,
I now run into the Shimano MA, MB etc designations,
50/34 which is currently fitted on the bike is MA
52/36 is MB
Does this mean that any attempt to 'change up' from the British Cycling U16 reg meeting 36T ring to the 50T will result in chain mangling?Won't be a problem on the Hillingdon track as the larger ring will be 'locked off'.

Thank you for your prompt answer.
looking at the frame, a Cube Agree,
the chain stay looks as likely to be snagged as the seat stay.
