Cassette, Chain, Chainset advice!

by SammyG   March 26, 2012  

I need to replace my cassette, chain and chainrings.

I am currently riding a compact 50/34 sram rival chainset, with a 11-26 rear cassette, and a sram chain.

I'm thinking about replacing the cassette with: http://totalcycling.com/a-z/cassettes/cassettes_road_10sp/cs_sram_rival....

and the chain with: http://totalcycling.com/a-z/chains/chains_10sp/CN_SRAM_1070.html

and the interesting part is the chainrings, i was originally just going to buy some new rings but I can get a brand new like for like Chainset from Evans for £86 which is appealing. But my question is should I instead purchase the following SRAM Red chainset?!: http://www.evanscycles.com/products/sram/red-chainset-52-38-ec034788

Any advice on any part of this would be great!

Can I ask how you know you need to change your chainrings? It makes sense to change your chain when your cassette is worn but chainrings last an awful lot longer.

Not that I want to dampen your enthusiasm to upgrade Smile

Personally I'd look to make sure my wheels were as good as they can be before spending big bucks on a chainset.

Chainrings are really badly worn, some of them are barely nubs and the others are getting really bad. The chainset, chain and cassette have 10,000 miles on them. You think its just the chain and casette needing replacing?

Oh I'm upgrading some Mavic Cosmic Carbones aswell!

my 2p worth - I'd go for a KMC X10 silver fully plated chain which are cheaper than SRAM and just as good in my experience, they also have a reusable quick link so you can take them off for cleaning. The quick links on SRAM 10spd chains are one time use only.

Cassette wise - nothing wrong with the SRAM cassette but you could probably pick up a shimano 105 cassette cheaper which also has the outer sprockets on a carrier.

Finally chainrings - SRAM chainrings are crap in my experience, I've got 2 SRAM chainsets and the rings wear incredibly quickly. I would keep your chainset and with the money saved on the above parts, fit some quality machined rings from TA or Stronglight.

Would it be possible to post some links to compatible Chainrings Joe?

I've used both makes and I think TA edges it in terms of finish and longevity. BTW - I'm not specifically endorsing Spa cycles (although they are good) so you may be able to get them cheaper elsewhere

Two sources of chainrings I'd try, from google/memory:

http://www.spacycles.co.uk/products.php
http://www.sjscycles.co.uk/chainrings-dept49_pg1/

If you change to a 38T inner ring bear in mind that it might be a bit tougher to get up some steep hills. 50x11 is already a pretty big top gear. Unless you have a pressing reason I'd replace the chainrings or get a like-for-like compact chainset (you could possibly sell the old cranks on ebay if you were so minded).

Unless you want a change of ratios or are unhappy with it I'd replace the cassette with the same model.

Excellent I think I will go with the T.A. 52/38 setup, I'm presuming as long as it is 110mm it will fit onto the compact crank no problems?

Hi Simon, I'm thinking about a 52/38 setup as I can get up the hills with a fair cadence not in my easiest gear on the compact setup.

My reasoning is that it will force me to increase my power output when climbing and therefore make me stronger.

unless you find that you're regularly running out of top end I would stick with a 50 at the top and maybe a 36 inner for a smaller jump between them. Alternatively a 48/34 combo gives a better shift than 50/34 and you can still crank yourself up the hills on a big gear if you really want to punish yourself. Smile
