I'm basically out of ideas on this one so could do with some outside help / opinions.
I'm getting a weird ticking noise intermittently when peddling. It's specifically there when peddling, not when coasting and it doesn't happen when it's in the stand - only when I'm on the bike (seated or standing). I've gone through the usual suspects like swapping the saddle/seatpost over, tried a new chainring, checked dropout/wheel alignment (though it's bolt-through rear end with direct mount hanger). Happens in any gear but seems to happen more when going uphill so with more torque but unfortunately not at any particular point in the cycle.
I've tried changing the rear mech, checking the BB is done up and running smooth as well. Doesn't seem to manifest itself as anything other than an annoying and slightly unsettling noise.
Santa cruz bronson, arch ex rims on hope, XT chainset with fat/thin ring running 1x10 with a hope 40t expander. XT chain, XT mech on direct mount.
Any advice on things to check greatly appreciated.
