12 x 157mm thru axles?

My son's Merida One-Forty is fitted with DT Swiss RWS 'thru' axles, the rear I believe is 12x157. The release handle has been broken off, and I'm trying to find where I can get a replacement part, or entire axle. The "I believe" part is that we don't have any useful specs from Merida, so we simply measured the axle: length is approx. 159mm to the thread, and 171mm including the thread (i.e. end of axle), i.e. closest "standard" size seems to be 12x157.

The thing is, a 157mm length seems to not be a (standard?) DT Swiss part - it's not listed on their web site, and places only seem to carry 12x142. I wrote to DT Swiss who haven't replied (nice customer service from a premium part supplier...).

There seem to be heaps of places selling 12x157 hubs and conversion kits, so where do they get their axles from?

Fantastic, thanks 'c'. I measured the frame spacing, and it's indeed spot on 142mm. I'll check the thread pitch just in case (should be 1.0mm I believe), but otherwise looks good!

In hindsight, I guess it makes sense that axles are 'sized' according to the frame spacing, not the actual axle dimensions.

The thread pitch on my axle is 1.5mm, the "X-12" at CRC is 1.0mm.

Turns out 1.5mm is the "E-Thru" standard, CRC are out of stock but lo and behold Cell Bikes have a Shimano axle that ought to work:

... and it's about half the price. Only difference seems to be the Shimano has a traditional QR-style clamp compared to the DT Swiss' ratchet, no great loss.
