Hi M-power,I have this,it’s a Syntace mtb stem,110 mm reach ,only 1cm rise ,1 1/8” steerer, but this was a very expensive piece of kit when I bought it.
I paid around £100 for it way back when I bought it for my WTB Bon Tempe.
It’s very light but very strong ,I think they rated it for Down hill use even though it was marketed as cross country,I mated it with a pair of Syntace titanium reinforced carbon bars (which I still have)
How does £40 sound
