Road to track - two part question...(15 posts)

Road to track - two part question...TFerguson
Nov 16, 2002 1:32 PM
I'm converting a 130 mm spaced 2000 steel Bianchi Volpe to a track bike for next spring.

1 - I have the cheapest Suzue flip-flop with track threads on one side and freewheel threads on the other. If I re-space it to 130 mm, I will have to put the spacers on whichever will be the non-drive side to have the chain line up. This will mean that the other side cannot be lined up (i.e. no longer a flip-flop). Right? (aside: This Suzue is the worst rolling hub I've ever felt – normal?)

2 – I've seen a lot of posts and articles on spreading old steel frames to 130 mm, but never on cold setting one narrower. Is squeezing the spread on this bike an option? What about the new chainline?

TIA,
TF

Maybe 130 to 126, but 10 mm is too much for cold set.
On a steel bike? I wouldn't worry about it.Humma Hah

If you can't make up your mind and bend the frame a few hundred times, maybe that will start to cause a problem. I'd stick a big piece of steel threadstock across the dropouts and tighten, scrunching the frame in small increments until the desired spacing is achieved.

But your bottom bracket shell is not wider. Are you planning on using the inside chainring on your crankset? I don't see why is your chainline will be off. Center the hub with spacers and you should be fine. If it is off, it might be easier to use a narrower BB spindle.
It came with a Tiagra triple...TFerguson

and my plan is to get a 2x BB (107 mm) and use the 42t middle ring. I think this will be the same chainline as the inner on a double with the same BB. Is this correct? Or should I look for a double?
The question of chainline above is that if I center the 120mm hub by either squeezing the 130mm frame or spacing equally on both sides, the right side will be moved inward 5mm.
Right now the chainline looks about perfect with the extra 10mm spacers on the left side of the hub and moving the center chainring in 7mm with a new 2x BB.
Thanks for the reply,

My LOOK is spaced at 130mm and I'm using 120mm Dura Ace track hub with spacers. When I first built the bike, I used the inside chainring on a double and had no chainline problems. I'm now using track cranks and still don't have chainline problems.
5mm spacer on each side? (nm)TFerguson

Yes, it works great. nmDave Hickey

I like good ol' cup and cone bearing hubs. I have the same basic level Suzue hub and it works fine. I always repack new hubs out of habit. Mostly so I can adjust the bearings to my liking, and second to use a better quality grease. Your hub's adjustment sounds too tight. It skips and grabs, right? Some of that will go away with a few miles of riding. Try it and see. Riding with too tight bearings can cause excess wear, so don't go more than 30 or 40 miles without checking for improved feel.

Fine tuning them can be a challenge at first, but use Sheldon Brown's article as a guide: http://www.sheldonbrown.com/cone-adjustment.html

I had to adjust my rear hub just tonight after 2 weeks of riding because it was slightly loose. It should stay tuned for quite a few months now that it has settled in.
It is new and I repacked and adjusted it, but...TFerguson

it feels very rough even with a little play still in it. I like to build/repair wheels and have a couple dozen hubs around from DA and Record to C-201s off of a hybrid. None are this rough.
What grease do you use to pack your bearings? nmbigrider

Most of my bikes are other than 120mm track spacing. There are available longer axles and spacers from Sheldon at Harris Cyclery.

Just build up the hub in question with the proper spacers and you should have no problem. The folks at Harris are very helpful and probably as knowledgeable about conversions as anybody. A great resource.

The second part of your questioned may be answered by the checking of your rear Drop out alignment. I had a bike that used to bind the bearings enough when the longer axle flexed due to increased spacing that I could never get it adjusted quite right. I finally figured out that the left dropout was not quite in alignment to the right one and when I bent it back in alignment all the proglems were resolved. I had never changed the alignmeent but had bought the frame used from a bike store. Who knows what went on with the previous owner.
