Singlespeed & Fixed Gear - New bike, Campy chorus rear hub has no threads for lockring...

I have a Campy chorus rear hub and noticed that there's no thread space for a lockring. What gives? This is a track specific bike but sheesh, I would like to be able to stop (skid), especially since there's no brake hole either. Am I missing something here or will this hub end up on ebay soon?

Is this bike second hand from someone who used it exclusivly on the track? Sounds like someone built it up with a road hub for track use. Not a problem on a 'drome where a good amount of people don't use lock rings, but I'd not use that set up on the road. That cog would spin off at the worst possible moment.

Yeah, 2nd hand exclusively on a drome. I'm afraid to ride it on the road not just cause of the absence of a lockring, but the geometry's got me hunched over and I feel like I'm going to ruin the tubulars over the imperfections on the road. A shame, it's such a nice bike... How can folks use a brakless fixedgear without a lockring? I mean, they have to stop sometime, right?

You can get away with not using them on the track cause there's not the same need to stop suddenly, no soccer moms in suv's making a right turn in front of you, car doors opening, pedestrians yaking on cell phones while crossing against the light, etc. Movement in general is more fluid. Even with crashes, the same mentality that works on the street- its better to avoid than try and stop is often used. I've heard them refered to by trackies as rookie rings, as experienced riders often don't use them as their bike handling skills, instinct, tendancy not to panic or whatever are better. Also, if you are pushing a big gear at a high rpm with your feet double strapped or bolted to the pedal, and someting bad happens it can be better to spin a cog off than have your knees explode. Rubber legs or back pressure will slow you down. You're not going to stop on a dime, but there's not a need to.

Is the hub not threaded for a lockring or are there not enough threads for you to say... put a bottom bracket lockring on with a bit of loctite?

ghetto. get a new hub.

record is the only campagnolo group that has track specific parts.

ghetto? why is repurposing something ghetto?

The same reason repurposing a blender to perform a circumcision is ghetto. Why risk it when there is a perfectly good cleaver in the drawer?

he makes no mention of having a track hub on hand, so your cleaver analogy doesn't fly.

It does put painful thoughts in my head though. Now I think I will ride off to buy bike tools.

Have a good day all.

I never said the cleaver was on hand either. It's in the drawer, alluding to the fact that it may still require effort to obtain. However, that effort is worthwhile. Using the proper tool could save hours of bloody clean-up be it a botched blender job, or a spun off cog at a downhill intersection. If you're serious about riding a brakeless track on the street, a glued hub is a bad idea.

I'm not trying to start anything here, and realize that this has been kicked around before... but I have never had a glued hub fail. The only negative I've experienced is when you try to do a cog change. It's pretty well impossible.

I think we are all missing the bigger picture......namely the picture.. of the bike. Rule #345 of posting to this thread about a new bike, attach pic of bike. Then you get help. :)

Either swap the fork for a road version that has a hole for a brake. If you must run brakeless, get a shop to rebuild the wheel with a track hub that has a lockring provision.

Now, where's that pic?

You're right, it's a record. Here's the pic. No threading left.

Alright... here a pic of the whole bike. You may have seen it on ebay several days ago. What an incredible bike! I may have quite possibly robbed the guy who sold it to me. Looks like I may be needing that new fork, then?

Has the axle been respaced for that frame? Record track hubs are threaded for a lockring (and they are NOT cheap.) It just may not be showing.

That is a great looking bike. Love the angles and the fact that it's running dual 700c's to boot. Was it originally a 650c front?

Congrats.

Thanks. No, it was custom designed to run dual 700's. I always wanted a bike with a sloping top tube and tubulars.

Shadow,

How can I tell if the hub's been respaced? I don't see how it can't be showing. All the other fixed gear hubs I've had experience with had two sets of threads. A smaller one threaded backwards for the lockring.

i did indeed see that bike on ebay and yes, it is sweet. mark nobilette (the guy who built the frame) was one of a group of slightly older cycling fiends who inspired me toward a lifetime of riding many many years ago here in treetown. you got a good one...enjoy it!

Unless there is a spacer a Campy track cog should leave threads showing for the Campy lockring. Yours looks flush.

that is a ROAD hub. that hub has definitely been respaced. all of those spacers on the axle are there to compensate the narrow width of a road hub with no freehub body in a track spaced frame. that wheel would only be safe to use on the track.

if you want to glue your bike together like some ghetto bum bike rig, then do it. it's not my bike. "it hasn't failed for me... yet" mentality is fine for your own bike, but it is not valid advice to give out to someone trying to learn something about fixed gears. it is possible to shift a manual transmission without a clutch. just because i can, doen't mean i should and certainly doesn't give me the right to tell others they don't need to use their clutch because "it works for me".

F' it. Make sure you buy the most expensive wheel you can get and post pics to see if everyone approves.

when did anyone say anything about him buying a top notch wheel for cool points? are you just sore that you're trying to dole out misinformation and were called on it? don't be a cry baby.

It's not misinformation.

You guys were right, it is a road hub respaced and redished for single speed. Anyone know how much I could get for this hub on ebay? Also, anyone know where I could get a good price on a Phil Wood 120mm track hub?

www.businesscycles.com has a great selection of track parts for reasonable prices.
