    Is there a noticeable difference changing from nine speed to ten speed ;)

    As a recent crash left my LH STi...totalled.

    Was thinking of changing, as this could be an excuse..:sad:

    l@.
     
  2. Yeah................chains/cassesttes are more expensive.....chains snap becuase they're too narrow(my mates snapped on the Sunday run last week and it had benn on about 6 months and not done that many miles - a Campad one at that!)..................set-up is more critical as there is less tolerance..........likely to wear more than 9 speed set-ups 9all things being equal).............

    Oh and you get an extra sprocket with 10 speed of course ! Wow - an extra sprocket !

    10 speed was(is) a marketing ploy by Shimano and Campg to get us to spend more money on upgrading our current set-ups.

    Very few of us actually need 10 sprockets on the back.

    Chains only break if you don't take care when joining them, the only one I have ever had let go was a 9-speed. The rate of chain wear is just the same, the sprockets are exactly the same as 9-speed, it is only the spacing that is different.

    Set up is no more trouble on a ten and stays in adjustment just as long, if anything the shifting is a bit smoother. Whether you change from 9 to 10 is all down to if you want an extra cog or not.

    And to account for the difference in spacing I believe the side plates are narrower on 10 speed so the same force is concentrated on a smaller area, increasing the wear rate.

    Having said that, I haven't had a particular problem with my 10 speed chain.

    Chains don't stretch because the sideplates wear, it is because the pins do on the inside of the rollers. It is the same with breakages, the thickness of the plate doesn't matter provided the plate isn't bent or the hole enlarged by careless fitting.

    I changed from 8 speed down tube to 10 speed STI early last year. The difference was amazing...when it came to the STI's; the extra sprockets made little difference. In fact when I came to change them (they'd obviously worn far quicker than the old 8 blocks ever did) I noticed that all the wear was on about 5 sprockets - the same 5 I usually used on the 8 speed block. In fact they correlated exactly with the 5 speed block I was using when I got my first road bike.

    Quite right this, but give Shimano a bit of credit - they released their 10 only after Campag had started producing 10 speed stuff. At the time of nine speed cassettes Shimano said that there was no need to add any more sprockets. Of course once Campag released a ten Shimano had to match them.

    You have to understand why people use ten speed blocks before you criticise them as being unnescessary. They were developed for racing cyclists where the ability to have an extra ratio can be an advantage, as speed can be maintained without big changes in power or cadance. Shimano made the change to ten under pressure from the pros they supplied who felt that riders on Campag systems had an advantage. However slight that may have been, every iota matters at that level.

    I would agree that for recreational riders the extra sprocket makes little or no difference, but most people like the latest gear anyway.

    my new one has got 10 speed campag and I love the close ratio, really love it after the previous hybrid

    granted I might not notice if someone changed it for a nine speed

    chains don't STRETCH! fools! they wear!
     
  11. Didn't Armstrong win 4 Tours on 9 speed stuff - a couple of those when Campag riders were on 10 speed ?

    Fat lot of good 10 Campag was to Ulrich !

    pff. 10 speeds indeed.

    Did a 68 mile ride this morning and I think I only used 4 of the rear sprockets.

    Living in Ipswich dudi, I'm surprised you need more that two sprockets. One into the wind and one with it behind.

    Down here I use all ten and both chainrings every ride.
