New Drivetrain

Simonb256

Hi all,

I'm currently using a Tiagra triple chain set and tiagra front and rear mech.
I'm in need of replacing the casette chain and chainset.

The chain and casette are badly worn and the chainset I've killed.

Can someone suggest decent possible upgrades for these assuming that I am running 9speed.

Budget is just under the £300 mark.

I am from a MTB background so I do not know road parts that well.

I am a heavy rider though which I feel should be taken into consideration, doing about 1000 miles a month.

I am not sure how much the next level up would be (Shimano 105) but you might like to look at prices of complete groupsets as these can work out cheaper than buying individual parts. 105 is 10 geared based but if you get the groupset you should be OK... I believe the 10 cassette will fit the 9 Tiagra hub but am sure others will confirm that.

Cheers, Phil

Triple at £307 for the full 105 groupset.

A 10 speed cassette with fit a 9 speed hub with a spacer, so no problems there. Obviously, a transmission upgrade would be to go to 10 speed, so you'll need new shifters/leversand a rear mech - you'll get away with your current front mech. Whilst 105 levers and a gear mech are fine - you may be able to find deals on Ultegra. It's also worthwhile spending extra on the chain - something like the KMC SL run smoother and last longer in my experience. Also consider getting a decent chain cleaner bath to keep your transmission in tip-top condition and longer-lasting.

http://www.ribblecycles.co.uk have the 105 triple groupset (and double) for under £300 (an impressive 27% off).

Surprised that none of the Campag crowd have jumped in here suggesting an alternative :?

I would do this cheaply.
1) new cassette and chain. Strongly recommend a Sram chain. Shimano ones have a mickey mouse joiney pn.
2) it will probably be cheaper for you to buy a new (discounted) chainset than replacement rings. Any 8/9/10 speed chainset and bottom bracket would be a good bet. 06 Campagnolo chainsets are being cleared out atm, and these are really good. Campagnolo rings are great. Try looking for a Veloce or Centaur triple. Your alternative here is to buy three TA or Stronglight replacement rings for your current chainset.

You could probably also find 105 or Ultegra 9 speed bits. Otherwise, you are looking at a full 10 speed upgrade, in which case your best bet is a groupset.

If you get a Campagnolo groupset, you would need a new rear wheel. But they are really nice

Wow so many suggestions :-)
I would give the SRAm a miss. You can find quite a few bad reports about SRAM.
You do not need to upgrade to 10 speed, do you really get any benefit from one extra gear?
As long as your shofters are ok just go for chain, rear cassette and chainset and the newr tiagra is apparently very good but you could go for 105.
Probably better off going for compact chainset so if you do not currently have one, you may have to adjust your front changer afterwards.

Oh by the way, I may be wrong, but as 9 and 10 speed cassetes can fit on the hub I do not think you need a new rear mech should you choose to go for a 10 as the travle of the rear mech is within same range.
You would however need 10 speed sti's, more expense!!
If it was me I would go for the cassette, chainset and chain

oldwelshman

Bugger it must be late I did not notice original post where it says tripple :-) Ok go for new tripple, cassette and chain

There have been some problems with Sram groups, but their chains are awesome. And have been for years!

I am now very weary of SRAM chains. I used to swear by them, but apparently they switched their production as the quality of the last couple I got were terrible. They lasted no time at all on my mountain bike and I have since switch to a Connex one and that's working out really well.

Perhaps they've sorted out these problems, but I am certainly avoiding them and not recommending them to my friends until I hear differently
