Hi, I'm fairly new to this and I was wondering if this used Bianchi Pista is worth 900???

This is what the ad said:
Blue Bianchi Pista frame, deep v wheels with machine side walls

Nitto123 drop bars
46/17 gear ratio with flip flop
All parts (wheelset, crankset, etc) have not been ridden
Will include tape, pedals, front brake set, chain

And if it were a good deal, would you guys advise changing this bike into a road bike? I'm not into fixies and this is more in my price range than a brand new bike and it's in my size. Please let me know anything I should know.... Thank you so much!

Nope. You can buy a brand new Bianchi Pista for $800.

Plus there's a possibility you're going to get it built and serviced professionally (possibly free for life) from your bianchi dealer LBS.

Plus how do you convert a fgss to a "road bike" if it wasn't previously a conversion?

It depends on your definition of a "road bike." I consider all my SSFG bikes that I ride regularly on the road to be "road bikes." Not all "road bikes" have gears, ya know.

Road bikes typically have gears. That's the accepted norm.

So, what do you call a singlespeed bike ?

Singlespeed/fixed gear.

Funny, I call mine a singlespeed road bike, because that's what it is. Just like cross bikes can be either multi-speed or single-speed.

Now, IDK what the OP wants or if the OP even knows what he/she wants. One thing I do know is that these discussions are often chock full of assumptions without any basis, other than the preconceived notions of the poster.

I call my ss and my fg just "single speed and fixed gear". But when people dont know about bikes I just say I have road bikes with no gears

It's actually extremely possible, albeit with a smaller cassette. This guy did it to his Kilo Team
Mercier Kilo Team 1X5 - Pedal Room

That's a slick little set-up. I would've face the binder bolt on the derailleur hanger the other way tho.

No no, you call it a "Fixie", especially if it is actually a single speed... right? Ahem.

I do agree that the terms "single speed" and "fixed gear" technically should have nothing to do with the type of bike. My Electra Rally Sport is a single speed.... and even though it has racing stripes, it is not even remotely a "road bike".

Terminology can get a bit weird, though. I see people referring to geared bikes (often IGH) as "fixies", because they look like "fixies".

Basically, it's a bit unpractical to try to identify the type of bike solely by the type of drive train...It's a bit like identifying your bike by the material it's made of, yes it's relevant information, but it isn't enough information...

Road bike. Track bike. Tarck bike. Fixie (that's what I call my neutered male cat). Fixed gear. Single speed...blah, blah, blah...

Who cares? Let's all get Boosted Boards!

And to think I could've had a pista instead of building up my black label... mannnnnnn
