You can just about see the difference here I think:
Re: 17 deg 3T stems
It's been well documented that 3T ARX -17 deg stems measure about 0.6-1cm longer than they are marked (depending on length). They have been that way since first hitting the market... and yes, this is by measuring them the "correct" way of c-c along the side.
That's incredible - what is the manufacturer playing at? And here was me thinking that a 2mm inaccuracy was pretty shoddy.
I always wonder how the law stands on these things. If a stem is sold as 110mm and it's 117m, presumably you have grounds to return it as unfit for purpose. 5mm (for me at least) can make a significant difference to setup.
I was just reading about the Enve zero offset seatposts actually having an offset of 5mm, although they are described as zero offset in all descriptions, including on the manufacturer's website.
Makes you wonder about frame geometry etc - how do you know that a seat post angle described as 74 degrees isn't going to be 73 degrees?
