used dura ace vs new ultegra
Postby RRalphy » Fri Sep 27, 2013 5:07 pm
option 1: dura ace 7900 groupset slightly used (~1000km) for $900
option 2: mix matched groupset new ultegra (chain cassette brakes) and used (500km) dura ace (RD FD cranks and shifters) for $800
option 3: brand new ultegra 6800 (11 spd) from the UK for $860
which would you go for? is dura ace so much better than ultegra to warrant me getting moderately used parts instead of getting brand new ultegra? I know the dura ace will weigh less (http://www.totalcycling.com/component-weights.html" onclick="window.open(this.href);return false;)

Do you have wheels? cos you'll need to factor that in if you go 11spd 6800.

others may think differently but personally... id go for the brand new ULTEGRA... peace of mindRRalphy wrote:I am currently getting a groupset together for a build and have the option following options and dont really know what to do, opinions would be valued:

you say its "slightly used" how slightly, is ...slightly?
1000km?... i dont recall groupsets having odometers... so you only can go by what people tell you and take their word for it.
i clean my chain every 30km ride... yes thats excessive... but 1000km with TLC i assume would be different to 1000km of someone that cleans the drivetrain once in a while.
my TT bike came with Full ultegra groupset except for the chain and the shifter.
i swapped it all to Dura-ace..just for the sake of it.. for the status..everything..rear + front derailleur, chain & even the composite $300AUD+ Pedals.
except for the crankset which i installed a Vision/FSA for the carbon look.
To be honest, feeling wise.... i don't really notice much of a difference.. and i dont think you will notice either.
same as the ceramic bearing jockey wheels and ceramic bottom bracket bb30 that costed just under $300... there was really no difference felt.
unless maybe the placebo effect.
imo... Ultegras work real flawlessly and seem to be based on the Dura-Ace designs.... some things almost look identical

DA 9000 is vastly more impressive than DA 7900 in terms of smoothness, ease and precision of gear changes.
I am presuming that the quality and design of the new Ultegra 11 speed is very similar to DA9000.
I'd go the new Ultegra.
My DA7900 has never changed gears in a crisp manner. It has always felt sloppy despite mine and several other peoples (including LBS and several "old hands")attempts to tune it up. I have read other like criticism of DA7900.

+1. Shifting is better on Ultegra 6800 versus Dura-Ace 7900. Brakes are better as well. Cassettes and chains will be a lot cheaper to replace.Tim wrote:I have been riding a bike fitted with DA7900 for about the last 4 years and recently bought a new bike fitted with Dura Ace 9000, 11 speed.

Hehe - that is a severe case of OCD. What would you do on a 100km ride, stop twice to clean your chain?DoubleSpeeded wrote:i clean my chain every 30km ride... yes thats excessive... but 1000km with TLC i assume would be different to 1000km of someone that cleans the drivetrain once in a while.
1000km is only one month's riding for me - with a wipe down and lube using R'n'R Gold once a week.
Assuming that the 1000km of use is correct, then that is nothing for a group that is built to handle a pro rider's 30,000 p.a. base kilometres.
The real question here is whether 10sp DA or 11sp Ultegra is better. Personally I'd go 11sp but I can understand the appeal of DA. However it is astonishing that a change to 11sp requires a new wheelset if that is true.

that's a 10 speed shimano free hub and a 11 speed cassette
that's a 11 speed cassette on said 10 speed shimano hub
how about a 10 speed zipp free hub

There is no need to change or modify wheels to use Campy 11sp. Campy freehubs are compatible with 9,10 and 11sp.Duck! wrote:What's so astonishing about needing a new wheel to suit the wider cassette?RonK wrote:However it is astonishing that a change to 11sp requires a new wheelset if that is true.

Campag cassettes have traditionally been wider than their Shimano equivalents, although 9-sp. was pretty close. That allowed a bit more space to pack the 11th gear in than Shimano's setup. As a side note, Mavic Shimano-pattern hubs have always required a 2mm spacer behind the cassette (my guess is it's a compensatory measure to correct for the flange spacing allowing the longer Campag-pattern freewheel body, although it's curious that no other manufacturer does this). As such, they're about the only older wheels that are 11-sp. compatible by removing this spacer.RonK wrote:There is no need to change or modify wheels to use Campy 11sp.
