What makes Shimano Ultegra Crankset or Cassettes better over 105, in Road Bike?
I have 105 Shimano Crankset in my Road bike. What makes Ultegra better over 105? Just 100g lighter and looks better? Does it really improves the performance and how? I need to know the effectiveness before I upgrade.
I have 52/39T front and 12-25 rear. What combination I am suppose to use for flat road?
The primary difference is the weight and its probable a really dedicated rider could tell the difference in the speed of the shifts. For most of us however, the differences would probably go largely unnoticed.
As far as actual performance goes, if both are properly adjusted its doubtful that a casual rider would notice much difference. A competitive rider might.
If you ride primarily on flat roads you could change out your cassette for a 11-23 that would give you a bit more top end speed but there’s a trade off… those higher cogs would make any climbs more of a struggle.
In my opinion, unless you’re riding competitively, the 105 group with the 11-23 cassette would serve your purpose and save you a bundle of cash for a very small return in weight savings. Besides, if you ride primarily on level roads that weight savings would be even less noticeable.
