    I bought a Bianchi with a Campag front chain ring. After a bike fit I was told the crank arm was too big. I’ve swapped it for a smaller one but now have a perfectly fine chain ring laying around. Is there a forum or group dedicated to Campag parts or do I have to resort to flogging it on eBay?

    I’m not implying anything. I’m stating that because of the relatively short length of my legs the man who did my bike fit suggested that a shorter crank arm would be more suitable than a longer one. 

    The whole crank debate is exactly that…a debate. There are many different schools of thought. Generally, the difference is marginal for most. For the vast majority of people +/- 2.5 or 5mm won’t make much difference. For people with significantly shorter or longer than the average legs it makes the angles your joints make during pedaling action easier. I have slightly shorter than average legs and disproportionately so to my height, so biomechanically I should prefer shorter cranks. Pedaling style also has an influence on crank length preference. As I’ve said, I’m a masher, having grown up with one bike sporting a 52/42 front end and a 12-23 cassette. I have therefore got used to churning big gears at lower cadences… I technically therefore favour longer cranks. However, I regularly ride 170, 172.5 and 175mm cranks and I really don’t notice the difference.

     

    Apologies for the missing or slightly strange wording in this post. I was on my phone at the airport and predictive text/autoincorrect were winning. Hopefully, you’ll get the gist of it.

    But it’s easier if you’re a spinner of lower gears.

    I’m a lifelong masher of pedals so I prefer longer cranks

I take it you’ve replaced this with another 53/39? If so, you may want to consider a bigger cassette to help on hills. You could go up to 29 assuming you have a short cage mech.

     

    I replaced it with a compact 50/34 as that’s what they had in the shop on the day and I had never intended the bike to be my dream ride. It’s actually quite hideous being Shimano Sora. Very out of keeping with the Campag Record rear derailleur.  My rear cassette is 10-28 and 10 speed. My LBS mechanic said  an 11 cassette wouldn’t fit on the the hub although I don’t know why. I’m sure the rear derailleur has the short cage mech. I could do with a 32 rather than a 28 though. Rode up the Stelvio two weeks ago on a hired bike which had a 32 on the back and although the crank arm was bigger than my recommended 165mm I did appreciate the extra teeth. Didn’t have an oxygen tank fitted to the frame though. 

     

    I’ll give the parts a clean and whack them on the classified pages here and maybe eBay (although I hate that site). Thanks for your advice.

    Thanks for the info, Jack. Here is a pic of the inside. Surfaces look okay but not immaculate. The arm length is 172.5mm. I was recommended a 165mm arm so I swapped it out. Still struggle up-hill though!

    Okay… So what you have is a

    Okay… So what you have is a Bianchi carbon fibre 53/39t square taper chainset. Turn the cranks over so buyers can see the inside surfaces.

    Also worth stating what length they are in any title description – there should be a sticker on the inside.

    I’ve seen these before and it’s probably worth 50-75 quid to someone. eBay has a bigger potential customer base, but you might as well try it in the classifieds here.

    There is in fact an identical set on sale on eBay right now

    Sadly, it’s not what I’m looking for myself.

     

    Good luck with it. I hope you make some cash.

    Please excuse my absolute idiocy but on checking my ‘Campag’ crankset I discovered it is in fact made by Bianchi.

    By how much… 2.5mm or 5mm?

    I think he means crankset.

    For info, I recently sold a just-about-new Shimano crankset on e-bay and got around £25. If you do a few miles it may be worth keeping it for when you need to replace the chainrings.

    Assuming it’s modern Ie 10 or 11 speed?

    There’s a classified section on here. http://road.cc/classified-ads Alternatively, it’s eBay tbh.

    Is it just the chainrings or is it the whole crankset?
