I'm looking to fit a 46t chainring to a Shimano Tiagra 4700 chainset but i'm having trouble tracking one down. There are a few available from Stronglight, TA or even Shimano but they all seem to be for 105/Ultegra/DA or GRX, would any of these fit? Although they all share the same 4 bolt pattern I don't know if the design is exactly the same, This is to replace a 50t on a compact chainset as it's what I like to run on my all road bike.
Thanks.
Bazz - I'm wearing out my Tiagra, then swapping to a SpaCycles 2x touring chainset to be able to have smaller and cheaper rings in future.
Not a bad idea there @matt_outandabout It means a swap to square tapered BB which isn't a huge issue as they last forever. At the moment i'm running a Tiagra 4500 with the old 5 bolt BCD and have a stronglight 46t on that, the main motivation for swapping is put on the grey coloured chainset as the current one is silver and looks out of place (to my eye) on the bike.
