Cervelo P2C to s/s

[warthog1]

I have a CF Cervelo P2C tt frame that is now no longer useable as a derailleur equipped bike.
The rear derailleur ended up in the spokes and it ripped the derailleur hanger, that is part of the frame, off.
Anyway, it has horizontal rear dropouts so why not rear purpose as a S/S?

Got a few questions as I am a single speed/fixie novice

I've had a quick look and see that track hubs are 120mm in the rear. The spacing on the P2 is 130mm.
It is fairly stiff/strong so I'm guessing that is going to be a problem?
Are there S/S wheels available with a 130mm hub?
Or is something like this the go?

It currently has an ultegra 6600 chainset in 53/39. I reckon I have a 44t inner ring lying around that will fit.
Can I use this chainset as a single speed chainset with just one ring?
Will the ring be in the correct spot laterally if so?

The washers in that kit re-arrange in whatever order you need to obtain an acceptable chainline. I think I might actually have one of these kits floating around (which I got as part of a bulk purchase).

I think that kit will be the only way to single-speed it, unless you shorten a chain so that it's an ideal length for one of the mid-range sprockets on the cassette and the inner ring, and just ride it like that...

It is, how do you say...inelegant, but would work, sorta.

[warthog1]

Hadn't thought of just using the cassette.

Bugger.
I was hoping a 130mm hubbed wheel might be available.
The disc wheel I have has the ability I think.
But tubular and disc. Not happening.
Frame may be a bin job.

Sorry

I can't see a reason why not.

If you want to use a nutted hub, then all you need is an axle that is long enough (many already are) and add appropriate spacers to either side. I prefer to add them between the cones and lock nuts to keep it all together. The 44T inner ring will give you an acceptable gear with a 16 or 17T cog.

You could also start use an old (80's or older) road wheel, which will already be 126mm OLD. You will only need to add 4mm of spacers in that case, but you may need to shift some from right to left for a decent chainline. Then it is only a short job to re-dish the wheel to bring the rim back to the middle.

Cheers,

Sorry

No, thankyou for your knowledge

Thanks. I cycle with a couple of bike mechanics from time to time.
I'll run it past them when I am back into it too.

I've thought of another option... I've already done this to fit derailleur gears to a track bike.

In my parts collection somewhere I have a rear derailler hanger that fits into a horizontal dropout. Like this.

This fits securely within the fork end. Whilst the bike I used it on held it in place with an axle nut, I think it'll probably also work with a QR nut (possibly with a 135mm skewer for the extra width). It's worth a try anyway.

I'm happy to post it to you if I can find it. Just send me the address.

Thanks Cameron
Never seen anything like that.

I am thinking a S/S is prob the best use for the frame.
I already have 2 roadies.
The best excuse for keeping the P2 was as a S/S as I don't have one.
There is some home pressure to be n-1, particularly after my crash.
Wife is not a fan of me cycling so much now as she got the worst case medical scenario from the staff
The P2 only carries 1 bottle also.

You are very generous but I wont use it as a geared roadie I think.
I bought a giant tcr frame to replace it when I broke it.

Are there S/S wheels available with a 130mm hub?

How did I miss this? All-City do a 130 OLD singlespeed hub: https://allcitycycles.com/parts/hubs/rear_hubs

Of course, they won't be cheap, you will need to lace them up to a rim and I don't know where you can get them in 'Straya, but it's an option!

Thanks mate.
The frame is still sitting in the garage
