If you can show me a study that shows one-legged drills can make you faster I'll reconsider them.
To save you googling, there's https://www.ncbi.nlm.nih.gov/pubmed/21330612 but it's weighted and high resistance which is basically like doing single legs squats rather than the single-leg spinning that TR does. Your time is better spent riding 'properly'.
