I need a new cassette for my road bike. It's currently Dura Ace.
With there being a £90 difference in the cost of the 105 v the Dura Ace, what difference would I notice between the two?
Does the Dura Ace shift better/wear better/perform better?
Why would I want to spend the extra?
Dura ace has some Ti cogs and its on a spider. Both made it lighter.
Dura ace will shift better, but both should last about the same.
DuraAce is lighter but probably shift slicker & wear faster,.
DuraAce
Close ratio gearing allows a more efficient use of energy through finer cadence control
Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
4 largest sprockets are made from titanium to reduce weight without sacrificing strength
Sprockets are extensively cut away and drilled to further reduce weight without reducing rigidity
Nickel-plated finish offers hard wearing resistance to corrosion
Alloy cassette lockring
For Super Narrow 10-speed HG chains
Weight: 163 grams for 11-23 tooth
105
Hyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under load.

Thanks for the help. I'll go with the 105!
