165mm Record Chainset?

brucey72

I have had a bi-lateral knee replacement and am making my first tentative steps back to cycling. I have 110 degree bend in each knee and my physio has advised that over the next few months this should increase to about 120 degrees. A keen cyclist himself, he has said that I should maybe look to replace my 172.5 chainset with a 165mm one as this will make it easier to cycle with a slightly restricted knee bend, but the problem is I am struggling to find one in this length.

My current chainset is the 10 sp 2008 Campag Centaur UT 34/50 and I was hoping to upgrade to Record or similar but I can't seem to find a 165mm one anywhere. Does anyone know where I might locate one or if not maybe suggest a comparable alternative to Record.

Many thanks.

sram red and shimano ultegra upwards do come in this length...
I run Centaur running gear but with a miche young chainset.(in 155 and never had a problem) It is a the old iso square taper BB though.

hope this helps.

SRAM Red:

maybe SRAM Rival?

Are these chainsets be compatible with my current Campag setup then? I hadn't realised that you could "mix n' match" so to speak.

I'm afraid Campagnolo don't do a 165mm crank apart from track - haven't done for years. Plenty of people run a 10 speed chainset with 11 speed - you can buy 11 speed aftermarket chainrings if you're really particular. Mix and matching cranks is no problem.

Thanks guys that helps a lot.

Wiggle are doing the SRAM Red Chainset for £229 which looks good value given the distinct lack of 165mm chainsets on the market:

Although I do most of my own maintenance my knowldge of this area area of the bike is limited. I want to do the work myself so the question is; will I need to buy a new bottom bracket and cups and if so which set? How do I know if I require Italian or English thread? My bike is a 2008 Wilier Izoard so I'm guessing it will be Italian thread and if it is, will this be any good?

Thanks in advance for any help.

Check out Ribble or Parker International - both have a decent selection and both actually have stuff in stock. They're really prompt on the shipping as well.

Good ol' fashioned quality run by guys who've been in the business for yonks.

Thanks for that. I have just looked and the Wiggle offer still looks the best. Can anyone help on my bottom bracket question as I'm hoping to get the chainset this week.

On an italian b/b both the cups will be regular threaded (to tighten turn clockwise) on an english b/b the driveside cup is reverse thread. There may be direction arrows (can't remember if this is just shimano) so you could try removing them to find out what you have. (my guess would be english)
