Hi,

I have just purchased a used FSA SLK chainset and want to upgrade the chainrings.  I currently run a 53/39 set up on my Moda with a 12/27 cassette but am looking for a little bit more assistance on some of the steeper slopes I encounter on the weekly club ride.  I am looking at using a 11 or 12/28 with a 53 or 52 outer and a 38 inner. My question is,  will they still be compatible or will I have changing issues between the two rings or will I have to stick to a 39 ??  Any help and advice is much appreciated. 

Steve.

Windwave are suppliers for FSA chain rings to the UK if that’s any help, their staff are pretty good if you have enquiries about setup 🙂

Have a look at these (http://www.ebay.co.uk/itm/gobike88-SRAM-Chainring-38T-BCD-110mm-39g-Black-765/161155266975?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20140122125356%26meid%3D713c8f111caa45f38628673bf3252497%26pid%3D100005%26rk%3D2%26rkt%3D6%26sd%3D151156980528)

i know the one i have listed is a 110mm version but i am sure they do 130s, i mix and match 36 and 38 inners with 40 and 50 outers depending on where i am going without any problem at all.

 

Sorry, that should have said 48 and 50 outers

Thanks everyone,

I have opted to go with an FSA 52/38 set up.  I will see how it goes when I set up my new EVO 6 Hi Mod frameset with it,  Fingers crossed now !!!!!!!!

You should also make sure

You should also make sure whatever front derailleur you’re going to use is going to accommodate the gap between small and big rings.

From what I know, many of Shimano’s road double front derailleurs have a maximum “capacity” of chainring difference of 16T. It’s not coincidental that many of their cranks use just that discrepancy: 53/39, 50/34, 52/36.

So far I’ve noticed it’s only the cyclocross cranks that have a smaller gap, usually at around 10T (46/36).

Thanks Doc,  I will keep to the FSA’s and go with a 38.

Thanks for the replies,  I

Thanks for the replies,  I have been looking at either FSA or TA chainrings,  they both seem to have good reviews.  I dont want to mix and match brands.  I will be running a 10 speed SRAM Force groupset apart from the SLK chainset but only have a short derailleur so can only go to 11 or 12/28.  The chainset is 130BCD so it seems I am limited to a 52 or 53 outer but my thought process was to add in a 38 to give me a little bit back over the 39.

What groupset type – Shimano

What groupset type – Shimano/Campagnolo 10/11-speed ? If you don’t mind the marginally wider gaps in a couple of shifts then perhaps just a cassette change might be worth considering considering, e.g. 11-32, 11-30

Hey up- you’ll need to make

Hey up- you’ll need to make sure both chainrings are a matched pair. Otherwise you’ll encounter serious shifting problems ‘cos the teeth on the chainrings won’t be aligned properly as your chain moves up and down- so you’ll end up with the chain trying to get pushed onto the top of the teeth of the chainring rather than into the dips… if you see what I mean…?
