Do they do a 46T chainring for Tiagra? I got a cx chain set on bike (ultegra) for this very reason, but the bike in question is replacing a mtb with mega easy gearing and is already at the top of the budget so I'm just trying to get as easy a gear as possible without breaking the bank.
Has anyone actually tried exceeding the capacity? If I size the chain for 50-40, is the worst case that it will be too loose if you cross chain in 34-11?

Does anyone do a 12 or even 13 or 14-40T cassette?
Trying to get some easier gears on a Tiagra 4700 groupset with a GS rear mech. 50-34 front so a 11-40 (with road link) would put it at 45T when the capacity is 41T.
Will it work ok past capacity or if not, is there a cassette out there that starts at 12 or higher? Top end speed is not an issue and it's not my bike so I really don't want to have a situation where is a risk in certain gears.
