I'm selling these cranks because I'm downgrading the Bling Bike - I don't use it nearly enough and it's much better than I am, or than I can really afford.
They've done 482 miles, according to my Garmin. This is practically nothing - the chainrings are virtually unworn, as you can see in the photos. The bearings are still beautifully smooth, they're Campag's CULT ceramic bearings so are not only ultra-low friction, they're very hard-wearing.
I went for the 36/52 tooth chainring setup because it's a great middle point between a standard setup (the big ring is only one tooth less than the 53t standard) and a full compact (34/50t, which means you don't get as big a large gear). Coupled with a wide-ratio cassette (I used a 12-29t) the gear range is almost as wide as a triple, which was fantastic.
They're 170mm long. This may be shorter than many people expect, but after a fitting session with CycleFit I realised that most of us are (and, previously, I was) riding cranks that are too long for us - I'm 5'9" with a 32" inside leg and 170mm cranks are the right size for me, apparently. Riding slightly shorter cranks has no significant effect on pedalling efficiency (you tend to become happier pedalling a slightly higher cadence) and can be much kinder to your knees in the long term. I noticed a power increase of somewhere between 5 and 10% after switching to slightly shorter cranks. The bike guru Sheldon Brown agrees, in the following article: http://sheldonbrown.com/cranks.html and I don't intend going back to longer cranks.
They're in excellent condition, with only one small scuff on the inside of the drive-side from the first setup of the front derailleur where the cage rubbed lightly against the crank. This only affects the lacquer and is tiny, and is virtually invisible when built up on the bike. The pedal threads are mint, the crank ends are perfect (I've never had "pedal strike" when cornering with these cranks) and I've never had any pedal rub so they are more or less as new.
I'll also include the Super Record Ultra Torque bottom bracket cups. They're for an ISO bottom bracket, standard screw-in fitting, but if you wanted to fit these cranks to a BB30 or other standard, there are plenty of adaptors available.
They're £719 new, the auction starts at 99p and there's no reserve (or buy it now price), so this could be your chance to grab a real bargain! Please don't hesitate to ask questions or request more photos if you need to. They're at my house in Catford, London SE6.
