Honestly, I wouldn't put a lot in to it except a good drivetrain clean and lube. She will probably outgrow it before any upgrades are put to beneficial use.
I'm not, but if I were to do it, I would probably opt for the Garmin replacement pedals. The other option would be a replacement left crank.
Well, new(er) Shimano SLX shift/brake lever combo (gets rid of twist grip), cables, tires/tubes, saddle, grips all combined runs about $120 total. The current seat, tires, and grips are toast and the cables are all-original and don't seem to slide/retract well. If I'm going through the trouble of getting new cables, the extra $35 for the trigger-style shifter and brake combo probably makes sense. I'm not planning on changing out rims or group-sets/derailleurs. No need for suspension-style forks either, as I think it would be a waste and it's better to learn on a rigid-frame (in my opinion). For $120-150 all-in, it should work for her for 2-3 years at least.
I have these Assioma Duo's . Been very happy with them and think they are really helpful if you are doing any serious training, particularly with intervals. I have a Wahoo Bolt that displays the power data along with pulse, speed and cadence. I can program interval sets based on any of those data points, but power is the one I use most. It also lets you see your improvements, which can be very motivating. When I am training seriously, I to an FTP test every four weeks or so and you can really see progress. You can also see changes in your power curve. (Power compared with time). If you are working on sprinting better for example, your 3 through 30 second power max gives you a sense of where you are relative to where you need to be.
Strava for me; I have a tendency to push my aerobic heart rate upper limit on longer rides which leads to the occasional blow up/wall being hit on hilly routes.
I do an FTP about every 3 months or so, ran by my coach. On the indoor trainer, I’m near religious on power/hear rate alignment, but when I get outdoors, without the power measurement I just go by hear rate alone.
Agree 1000 percent. Even if you don't geek out on power, HR, or other stats analyzing the ride data later is invaluable. I inadvertently messed up my home display screen on my Garmin, delved into it and entirely reconfigured it. For example, having real time average speed on the display is meaningless to me although it's a useful stat on Strava. I also opted to display battery power real time as it is somewhat pertinent.
I find power very helpful outdoors. I'm still using Powertaps on my wheels, but I'll switch to crank-based or pedal-based when I get me next bike. Power is much more instantaneous, whereas is can take longer for HR to catch up. That makes it a lot easier to stay in your zones. The metrics for power are a lot easier to track on things like TP, Strava, GC, etc. HR can vary a lot based on how well you slept, stress levels at work, etc. In truth, a combination of both is best - sometimes I won't be putting out the power I know I can, but my HR is much higher than typical. This lets me know I'm not rested.
Yeah I think you're right, I'm off a decimal point.

Interesting, Wilier was founded in Bassano del Grappa Italy. We are going there for a week of riding late spring followed by another week of riding in the Riccione area. Two weeks of riding in Italy. Woot!
