Hi all,
I have been time trialling on my road bike for a few years with clip-on aero extensions and have recently made the jump to my first TT bike. I have started with a position setup similar to my road bike (but with the saddle further forward owing to the steeper seat angle). I'm still getting used to training in a TT position so balancing bike fit with new aches due to using muscles in a different way in this position. I was hoping to get a proper bike fit to sort my position but due to coronavirus it's not looking like I'll be able to do that for a while.
As a result I'm trying to do my own bike fit by making small changes and recording a bike fit video after each to evaluate aero vs. comfort etc. I'm sure there are many people on this forum with years more experience than me on TT bike fit so in lieu of getting a proper bike fit I was hoping to get some advice on my current position and what changes I should be trying. Here's the latest video:

In general I think I have a reasonable understanding of the effect of hip angle on pedalling efficiency and aero bar drop and fore-aft for getting the back and arms at reasonable angles etc. but the bit I'm struggling to sort is saddle fore/aft position. I don't intend on taking part in any UCI events anytime soon so don't need to stick to the saddle nose 5 cm behind the BB. At the moment I've just put the saddle as far forwards as it will go (which is a couple of cm behind the BB, but it is a short-nosed Sitero). Pedalling efficiency feels fine in this position but I'm noticeably not on my sit bones which isn't the most comfortable, but perhaps just a case of getting used to it? My general plan is to keep dropping the front end incrementally once I'm comfortable in this position to get my back a bit flatter. I'm going to be doing most of my training for the next few months on the TT bike to get used to it / comfortable ahead of the season.
Any general critique / advice welcome!
