What are the best accessories for dumb trainer setups when the goal is to prioritize realism and immersion, rather than just getting a good workout - are expensive smart trainer-esque accessories like virtual training software and elaborate camera setups worth the investment, or can a well-placed fan and a simple resistance unit provide a more than adequate training experience.
In particular, I am curious to know if theres a point of diminishing returns with accessories like virtual training routes and live cadence tracking - do they genuinely enhance the overall experience, or are they just bells and whistles that dont provide a tangible benefit to the rider.
Furthermore, Id like to hear from those who have experience with both dumb and smart trainers - is it possible to replicate the feel and accuracy of a smart trainer with a dumb setup and the right accessories, or are there fundamental limitations to the technology that cannot be overcome.
