I went to look at a Sieber today and it had horizontal drop-outs instead of track ends. It was advertised as a track bike so I just assumed I’d find track ends. I’ve seen Siebers with track ends and a quick google search shows them all with track ends.

I’m wondering why this particular bike has horizontal drop-outs instead of track ends? And is it okay to ride this bike fixed or is it maybe a SS?

Do we have a resident Sieber expert? Any input is appreciated.
