|Playing bidding games for beater frames and fixie set-ups that aren't right for me, so I went to an LBS and got the last 57cm Bianchi Pista in town. Put a nice dual pivot brake in front, 19 cog in back... Just need to swap the pedals and get some work stuff done to take it for a spin.
Wondering what I'll put on the flip side of the hub. Any suggestions?

|pistas are cool, nice bike. keeping the industry afloat buying from the lbs rather than ebay too. well done.
Id either throw a smaller cog on or leave the other side of the hub empty. I put a freewheel on the flip side of my suzue last summer and spent all my time on the fixed side obsessing over the weight penalty so I took it off. versatility's nice though, espaecially as youve got a brake on the frt already. see what the gearing feels like on your ride and decide based on that.

|It wasn't my regular LBS. My regular shop was out of my size and referred me to this shop in a suburb. Awckk. But getting over that, I liked this new (to me) shop.
Creaking old bare wooden floors underneath - always a nice touch in a bike shop. Great bikes on display... B-stay C40, Pinarello Prince, etc., plus normal proletarian bikes too ... The wrench was way up on fixies: "I know the 200 fixie riders in town." My test ride was on a trainer, since there were no brakes on it... but that was just a formality, actually.
I think you're right. I wonder how often I'll actually switch the rear. Just need to get out and ride it... Learn how big/steep a hill I can handle.

|... you'll be able to handle more hill with time.
Whatever gearing you chose, within reason, will probably get you up the hills. Strength and physical conditioning will improve with time, but so will your skill at choosing the pace. Most new riders will try to attack a hill too fast, especially if they stand to climb. They end up going anaerobic and dig a metabolic hole they can't get out of.
Slow down, watch your breathing, and maintain a steady effort. My goal is to climb just shy of my AT, the fastest speed I can go sustained for the whole hill. Climbing any slower just prolongs the suffering.

|I suspect you'll wind up with about 3 or 4 rear cogs in your collection, most of them smaller than what you have now. You'll have a better idea after you ride it a few times.
I'm betting a 17T will be a reasonable next step, depending on your chainring size. From there, you'll go up or down as you feel fit. Typically, you keep the two sides within 1 tooth difference, two at most, depending on your dropout length, so you can flip-flop without changing chains.
One singlespeed freewheel might be a good bet if you're planning to ride in an extremely hilly area, or are planning a ride in excess of 100 mi.

|The chainring is the stock Pista 48, giving me a 48/19 - which correlates to about a 42/16.6 -- that 0.6 cog does a number on the chain...
Thanks for the tip on how close the cogs often are... and staying aerobic on climbs... I can do that pretty well in multiple gears, but this will be something new to learn.
|I'm also running 48T front ...||Humma Hah|

|... on the Paramount, 17 rear, and the cruiser runs 46:18 singlespeed. I guessed your chainring was not much larger, so 19T rear was probably about as low as made sense. Not too low: good spinning choice and could be really handy on long hilly rides.
The cruiser is trying to develop one of those fractional tooth ratios, like maybe a 46:18.1. This weekend it is getting a fresh freewheel, BB, and chainwheel. The old chainwheel is original (chromed steel), 32 years old, something like 30,000 miles on it, so I can't complain.

|I got me a 57cm Pista back in February. I love this bike more and more each time I ride it. I left the 16 cog and swapped out the chainring for a 42T. Bike is really versatile - ride it in the rain-the the quick geometry will help sharpen your handling skills and no messy components to clean!, use it for wind or hill sprints, take it out for a sunny afternoon cruise around town with your girlfriend, take it on a fast group ride, run errands. etc. etc! Sometimes when I'm feeling less than motivated to train, a nice spin on the Pista reminds me why I love to cycle.

|The flip side is not threaded for fixed, only freewheel. If you are running a 19 fixed, I'd put a 20 tooth bmx freewheel on the other side, if you want anything there at all. I don't run anything, as it forces me to suffer through an entire ride in the pre-selected gear - pain and knees be damned.
|There's a difference: fixed threads vs freewheel threads?||PdxMark|
May 16, 2003 7:37 AM
|There's always more to learn... I was thinking that the threads for fixed/freewheel were the same, just that a lockring was used with a fixed gear. I would have just tried to put a fixed gear on that other side... I guess I need to actually look at it now. Thanks.|
|They are the same...||SenorPedro|
May 16, 2003 7:46 AM
|It depends entirely on what hub you have though. The threading is the standard 1.37 x 24 tpi on both sides, unless you have campy. Some hubs have the "track side" with the threaded portion, then a shoulder down to the reverse-thread locknut section. This is then repeated on the other side, except that there is no provision for the locknut. Many hubs are like this.
Other hubs will have the reverse-thread section on both sides. You can often put a freewheel on one side anyway if there is enough threading.
|Ahah! The ol' shouldered down reverse-thread locknut section||PdxMark|
May 16, 2003 9:52 AM
|The light goes on for Maxwell Smart...
That's what I was unaware of... Can't readily see it when the cog and locknut are on there. On my hub, the reverse side doesn't have the ol' shouldered down reverse-thread locknut section, which means it's for freewheels... I get it... Thanks.
|freewheel side fixed cog with no locknut=bad||DougSloan|

|If no locknut used with a fixed cog on the freewheel side, you could unthread the cog if you apply backpressure, which could be catastrophic, locking up the rear wheel if it unthreaded and jammed.
|freewheel side fixed cog with no locknut=bad||PdxMark|
May 21, 2003 9:56 AM
|But that would be a different size locknut than on the fixed side with the reverse-thread smaller diameter locknut threads, right?
I'm liking my 48/19 gearing pretty well. I think the switch side is something I won't be exploring for a bit... Though there's a week-long, 500 mile trip in September... I'm half wondering if I could ride that with this fixie...
A guy in the building here got a Pista he's riding as a commuter with the original gearing. Ouch!
|locknut for non-fixed side?||DougSloan|
May 21, 2003 10:13 AM
|I'm not aware of a locknut for the "non-fixed" side, as it would not have reverse threads.
I've ridden with a 48x16 quite a bit, and it's ok except for climbs. Not bad for flats if you are going around 22-23 mph. Sort of hurts at the stoplight drags, though.
If anything, but a freewheel on the other side and carry another cog or two in your pocket for the long ride.
|Oh - I must have mis-understood your post...||PdxMark|
May 21, 2003 10:45 AM
|about a locknut on the freewheel side...
hmmm... but a couple extra cogs in a pocket... and a freewheel too... hmmmm... just gotta see how many miles & vertical feet I can handle.
It would be funny - though maybe not appreciated by my wife - to take the plain simple (cheap) Pista fixie on that trip while the nice slick Campy Litespeed hangs on its hook.
The thing is, there's no challenge in doing the week-long ride on the Litespeed. The fixie, on the other hand, evens out the odds a bit between me & the ride...
|Flip Flop Track hubs...||Dave Hickey|
May 16, 2003 10:19 AM
|A word of caution if you're using flip/flop track hubs(locknut on both sides) and a freewheel. If both sides have provisions for a locknut, use a high flange hub when using a freewheel. I have a high flange and a low flange Dura Ace track hub and the freewheel rubs the spokes on the low flange. There isn't enough thread to put a spacer between the spokes and the freewheel. On the high flange hub, the spokes are above the freewheel.|| |
