I’ve not ridden an MTB since around 2011, mainly do road now but just dug out the old SS in prep for an easy group ride next weekend

Just noticed the chainsets got a huge crack around one of the chainring bolts, whats the easiest/cheapest option for a SS square taper replacement?

I found the above but it dosnt look like you can strip it to have the middle ring on only, I’ve got an old Surly stainless ring on it at the mo so wouldnt mind keeping that running

I’d be up for cheap new style and BB if it works out same cost, Deore?
