Great cycle shop, Trek cycles a speciality, and they do a great cycle fit where you are set up on a measurement static bike, and they measure power etc and adjust the rig until they have it optimised. Then they can work with you to choose the right bike size and setup. In my case covid restrictions meant the bike fit was not available, so I bought the bike, then did the bike fit a year later, and they were able to adjust my bike to optimum set up. Helpful and professional.
