Hi all.
Just joined.. ive purchaed a triple crank 9 speed sora 3503 for my older btwin 500se. Will this fit.. i didn't realise that Sora had more than one version of the 9 speed crank. I currently have the claris version.
Also will want to update the bottom bracket. Has anyone done this?
Thanks in advance.

I can't comment on the 500se but plenty of members have upgraded their older models like the T3 from square taper cranksets to later hollowtech types with no problem. Typically from a triple to 10speed Tagra double.

Early examples of your model came with Sora as standard due to a shortage of the Claris cranks so yes no problem with the appropriate bottom bracket.
