Alternative to a TA 314 axle

I know the ideal for a set of TA Cyclotouriste cranks for a single chainring is a TA 314 axle [111.5mm].....that would be the ideal but what are the alternatives if a TA314 axle cannot be sourced?

The next question is, what is the correct axle width?....in ISO or JIS [if either can be used].

I'd appreciate some guidance on this matter.

Assuming a chainline of about 40 mm (which is normal fixed wheel) either an ISO 111mm or a 109mm JIS.
Both ISO and JIS will work fine with TA cranks, the tapers are identical.

i have to ressurect this thread cause i have the same problem.
i used a 110 jis and the cranks wouldn't even turn so how come a 109 jis would work?

just wanna add that i'm using a tevano track crankset made also by TA that requires the same axel 111,5.
i've tried an old Miche track bottom bracket and the cranks spin but the chainline is not correct, also the left arm stands way out.

Bit of a dredge. I'm in the same boat. Have read (Sheldon) that tapers are actually JIS as the Japanese 'borrowed' the French/TA size which became JIS.
So I need 111.5 JIS unfortunately in a French thread.

Need a TA 314.

aha

Get thee to Ripley. We'll ride there. It'll be fun.

it won't work. i've tried a shimano 113mm JIS and the cranks wouldn't even spin. i've also tried a miche 115mm ISO, it turned fine but as it's assymetrical, one side was way out.
you should try an axle with the approximate desired length and use french cups with it (english and french bb shells are both 68mm). you have to get the thickness of the cups right though... it's a pain!
if you have the chance, try a 113mm or 115mm ISO like campa or gpm, i'm convinced it should work (0,75mm or 1,75mm above the chainline, imho it's not a big deal).
please update this thread if you do try.
i have this for sale if you're interested:

but i'd rather sell the whole thing...
good luck!

Thanks^ good infos.
Is the TA 314 symmetrical?
I have some French cups already. I'm going to try TA344 with DS and NDSides reversed as a temporary measure.
Velo Orange do a French thread JIS BB but from what you're saying the 113 will be too short and the 116 may be too long.
If someone buys your chainset and doesn't want the BB spindle hit me up.

Paul bb works as chainline can be adjusted a couple of mm.
I just buy up all the 314's whenever I get a chace. Have a nearly nos in my tarck bike and a spare nos one just in case. Cups in decent nick seem to be harder to find than axles for me.
The axle is assymetrical with the drive side being ever so slightly longer but not immediately noticable.

Good luck in your quest!

A chap called Thurmer has a 314 on ebay and he will probably be at Ripley...the 314 axle is asymmetrical

Nice one, thanks Marxist.
I'm hoping to buy one from Mr. Liquidsky. But if that doesn't work out ....I'll do the bay. I looked the other day but missed that somehow.

On a side note, when is the Ripley jumble?

Next Saturday....go to Google and put in cycle jumbles.

My TA 314 exited this world last night in a vainglorious grind up Brixton Hill. I've taken it all apart and cleaned it up, the cups seem pretty squared off, but I don't really know how they're meant to start. The Axle has some odd pits in the ball races, and seems to have wonkily starting grinding against the mouth of the cups.

Are there any sensible source of replacement cups? How do you tell whether they're too worn.
Failing that, what can I replace the whole BB with?
Is ISO 113mm the best bet?

i'm using a campagnolo veloce 115mm and it works. the left crank arm is further out then usual and the right is VERY close to the bottom bracket shell... but it works fine (i haven't put a lot of power yet) and the chainline is correct.
with the ISO 113mm, the chainstay was less than one mm close to the crank... a hardcore sprint would probably damage the frame.

Thank you liquidsky.
I had a bit of a think & a fiddle with some calipers. I measure the TSA 314 as being 2mm asymmetric (i.e. 2mm longer on the drive side), this agrees with a gif on Sheldon Brown (19 vs. 17 mm): http://sheldonbrown.com/harris/images/ta-bb-axles.gif

Assuming the TA crank taper is ISO, the ideal substitution should be a 113.5 symmetric axle ISO BB (some places seem to suggest it is between JIS and ISO, at which point it would sit closer, I think). I can't seem to find much available in 114mm, so Liquidsky seems to have it right with a 115mm 'triple' ISO! Now to find a suitable BB...

& went with a Campagnolo Centaur, at a tasty £33.26 delivered from Ribble:

I'll report back with how I get on...

any news?

Apologies for dredging up an 8 year old post, however I am in need of a Stronglight 314 axle, the bearing surfaces need to be in good condition with a bearing span of 52mm.
I would consider an alternative.
Cheers

I think I have one.

Really..!
Wow..that would be great.if you did.

Gonna have a rummage right now

So sorry, bearing surface has quite a pitted area 8mm minimum. Basically scrap steel now.

Oh that's a shame, always seems to be the same with these axles, I've got plenty and they look superb, until you look closely at the all important bearing surfaces.
