Yes, the Apex supports upto 32. I have the Apex crankset itself with the usual 50/34 compact layout. I'm able to climb the Birla Mandir hillock here on my 11-26 itself on my Scott. So this should be even better. Compared to Shimano's lineup, Apex sits higher than Tiagra but more like a 10 speed 105. The Rival is a 11 speed Apex and the direct counterpart of the 105. Most things are cross compatible between Apex and Rival (even parts of the brifter, such as the paddles). I started liking this doubletap now.
I used shop tools to fix my headset but I did it myself under their supervision. I, however, also bought a bearing press as it's a good-to-have tool and will last a lifetime.
I did not find double butted spokes for the lengths I need. I had to get them cut as they were available at only 310mm. Also, my previous wheels were built with sapim leaders and they were really solid. So just went ahead. I'll get a spoke threading tool soon (again, available in local stores).
I also bought the iSSi road carbon pedals. There was only one pair in the mint gelato color and just couldn't miss them! I'll put them on the Scott if/when I build a trainer bike from it. They're Keo compatible. So I will need another pair of shoes as well :) But that's a story for another day.
Also, now I have a bag that fits my DJI Mavic Mini drone. So my bike is literally a pedal-powered aircraft carrier. It'll be interesting to attach a rack and permanently hold the drone on it. Like a helipad.
