165mm cranks for TT and triathlon bike setups

[freek]

165mm cranks for TT and triathlon bike setups - can they truly offer a performance advantage, or are they simply a relic of the past. Proponents argue that the reduced leverage and increased cadence associated with shorter cranks can lead to improved aerodynamics and reduced fatigue, but what about the potential drawbacks of reduced power output and increased stress on the knees. Are there any real-world benefits to running 165mm cranks in a TT or triathlon setup, or is it simply a case of chasing marginal gains. What are the key factors to consider when deciding whether to go short, and how do different rider profiles and course characteristics influence this decision. Can shorter cranks truly make a difference in the world of TT and triathlon, or is it just a case of shorter is better being a myth perpetuated by industry marketing.

Shorter cranks may indeed offer aerodynamic advantages and reduced fatigue, but at the cost of power output and potential knee stress. It's not a one-size-fits-all solution, as rider profiles and course characteristics play a significant role. For climbers with a more aggressive position, 165mm cranks could be beneficial. However, for pure power riders on flat courses, the trade-off may not be worth it. It's all about understanding your unique needs and the course demands. So, before you jump on the shorter crank bandwagon, consider your own riding style and the race terrain.

Shorter cranks won't revolutionize TT/triathlon performance, but they can offer advantages for some. Reduced leverage may indeed lead to improved aerodynamics and reduced fatigue, but power output could suffer, and knee stress might increase. It's a trade-off. Rider profiles and course characteristics play a significant role in determining whether to go short. For flatter courses and smaller riders, 165mm cranks might provide tangible benefits, while hillier terrains and larger riders may not experience the same advantages. It's not a one-size-fits-all solution, and riders should carefully weigh the pros and cons before making a decision.

Ah, the great crank length debate! To answer your question, yes, 165mm cranks can offer a performance advantage in TT and triathlon setups, but only for the right rider. The key factor here is biomechanics - if your knees are happier with a shorter crank arm, then go for it!

But let's not forget about the disadvantages you mentioned. Reduced power output? Sure, there might be a slight decrease, but tell that to your knees when they're singing praise songs at Mile 110. And increased stress on the knees? Not if you've got the right fit.

So, if you're a budget-conscious individual looking to try something new, why not give 165mm cranks a whirl? Just remember, what works for one rider may not work for another. It's all about finding what makes you feel like you're riding on clouds (or at least, not in agony).
