is it true that 53/39T crankset is more suitable for more advanced rider ( as in powerful ) to pedal ?
Cos i was thinking of getting this Sram Red chainset too as it's value for money and my local lbs told me i should stick with 50/34T ones for easier less tiring ride.
appreciate your comments...! cheers!
Changing ratios will not make a shred of difference unless you are experiencing one thing. The only reason to step up to a 53/39 is if you are running out of gears on the upper end and want a 53x12 or 11. If you already have compact, stick with it. A 50 outer is plenty big enough to push for the majority of mere mortals and if you decide to go up some properly steep stuff, you will be much more comfortable.
There are no set rules when it comes to speed. People always looking for excuses will turn to changing equipment. People serious about the training will eventually setlle into a reliable, trustworthy equipment set that lets them ride without thinking.
Pros are another ball game. They get given trade tools, set their fit up, and couldn't care what's under them. They are going to ride damn fast regardless. People read too much into what bikes are sitting under the world's fastest.
