Bob 74kg is pretty light. Add 20+kg and have go at towing the extra around 
We had last weekend a young man who is a true lightweight @ 55kg. He was blisteringly quick on anything with a slope. In fact he did a solo 2 hour sweet spot training ride the other day and average of nearly 22mph-gulp. Club runs are basically a stroll for him
