someone's selling some on ebay and i have no idea on their worth, nothing turns up on google other than a Bianchi road bike model. Is it the name of the Primato group prior to the name Primato?

you could just ask the seller?

Does it matter that much?

All the miche bit s ive ever had, including entry-level stuff has been very high quality.

If they come fitted with a 1/8 chainring its a good sign that they are track cranks.

Value id say theyll go up to £50 if they are 165mm, its hard to say these days. With fixie fever going around, any old tat that suitable for conversions is going for way above expected values. Definetley better than entry level sugino's

Id be happier to pay £30 though.

Trofeo = Trophy.
I'll let you know what they're like when they turn up ;)
They're 167.5mm, look nice, should be good quality and will match my Miche hubs.
At 55 quid delivered they're around the same price of entry level suginos on the bay so I thought I'd grab them.

167.5? Never come across that before!

167.5mm cranks aren't all that uncommon on road chainsets, Miche Advanced Track cranks come in that size as well.
