Sonic cycles. They have a 58t in stock.

That's one big scoblebrick

CTT illegal bar drop I reckon, without considering the lack of front brake.

46/14 would be about the same gear as I'm using at the moment

Mine
Is that ex-Danish National Team? Looks like the very rare Mk1 Ventus without brake lever pivots?

One of the Swifties rode my old club's 25, which is definitely not flat, on 65/13 yesterday.

on 65/13
Just went to plug those numbers into the calculator: it only goes up to 61!

How'd you get on?
-
Got a 56t Gebhart on the way
Me too: Bike24 was a few quid cheaper, although it's for the Sonic, so I feel a bit dirty now...
-
56:01 I think. 68rpm average!

131"

Smashed it! Time to gear-up, no?
Appropriate avatar is appropriate.

Will I die if I use it with my 1/8" setup?
Yes, but you will die either way. Low teeth tend to let the chain off when the slack run is feeding onto the ring, i.e. when you're applying back pressure.

2nd ever TT
Even more impressive!
Ordinarily you'd want to avoid ramps & pins (assuming you don't want your chain to come off), but I don't know if the wider chain would clear them.
Either way the teeth won't be full height, so you might as well do it right and get a proper ring.
You're 130mm BCD? Loads of old rings about, which don't have ramps & pins or a new one from Bike24 will cost you about £30 shipped, for up to 54t.

You mean this: http://www.bike24.com/p294943.html or this: http://www.bike24.com/p292381.html as @Pifko is using ⅛". As Bike24 seem only to have the black ones in stock, it's more like £40 for a 52T
£31.39 for Stronglight from France, up to 53T for the S/TK type. The Stronglight Zicral/7075 ones are a bit stronger than the Gebhardt dural ones, and the S/TK type are beautifully made.
