You're welcome here and lots of knowledgeable people to help. Many of us buy from UK sites as well so we can help with that. I would recommend going to the SPA Cycles site or if near North Yorkshire they have their shop there. https://spacycles.co.uk/m8b0s109p0/Drivetrain/Chainsets They have a mindboggling set of chainsets to look at but you are basically looking for the SPA brand with the TD-2, XD-2 or RD-2 prefix, Double chainring models. These come in many crank lengths and usually choice of black or silver and choice of various chainring sizes and grades of durability and all are JIS square taper. The cost generally determines the higher quality (durability) of aluminum used for the chainrings and arms. The only thing is to check the length of the Bottom Bracket recommended listed near the bottom of the page under "Description". If your current BB is a different length you may have to buy a different one. I've used them a few times and always good to buy from. I'm sure if you contact them they would be very helpful with any questions.
