Dura-ace cassette

[byegad]

Isn't it true that the top end cassettes are designed for racing with little or no thought to durability?

Of course...I'm surprised they haven't gone back to the aluminium alloy sprockets of yesteryear.

I think that is just a myth.

The Dura-ace and Ultegra cassettes for example both have protective 'coatings'. Whereas there's no mention of this coating on the lower end models.
(Perhaps the lower end cassettes don't need these coatings? )

I use the lower end stuff on my commuter / hack bike and the top end stuff on the race bike. The kit on the hack bike definately wears out quicker; but you would expect this. The hack bike isn't maintained as well and is used in all conditions. Whereas the race bike is only used when it's dry!

I ride 105 groupets, my old man rides dura-ace. When it comes to changing cassettes we both go for Ultegra. I reckon it's worth the extra few quid over the 105 (and I think it's better quality), the old boy reckons that for the £50 saving the difference in quality, longevity etc is minimal at best.

At Chain R**ction Cycles, a 9-speed Ultegra cassette costs £25 and has a reported weight of 235g, while a 9-speed Dura-Ace costs £48 -- and I know the 11-23T weighs 160g because I've got one. 75g for £23 is not such a bad deal.

That said, Dura-Ace is sold as a racing groupset and it must sacrifice durability in favour of weight -- so, as previous posters have said, the expense of running it is not just the initial purchase cost but also the more frequent and more expensive replacements. And while a light bike is a wonderful thing, losing grams can become an end in itself and a bit of an obsession.

Yours obsessively,

Why Chain R**ction Cycles instead of Chain Reaction Cycles? I'm seeing this more often on this forum and it doesn't make sense to me.

I think the idea is to avoid advertising! But it isn't a very effective disguise, I grant you!
