Hey
@ibbz, sorry abt the late reply.. i've been hotfooting it all over the place today..
Seems like the lads have got you on the right track
They are indeed SL-BS77 as
@Gtpulse mentioned, quality is fantastic, very positive shifting with a firm/fast/accurate clunk
^Truth
Only other thing worth mentioning.. the Paul Thumbies come in 3x different shifter mounts
Sram has negative square
Shimano has positive square
Microshift has positive square +thread
...so make sure you get the correct mount for your shifter.
I have a brand new pair of
Dura Ace Thumbies from SJS without the shifters.. if you want them for £20 shipped give me a hola
