Hey guys!

This site is just wonderfull. I've been reading ALOT about chinese carbon over at MTBR.com, but those threads tend to get really long and just not easy to manage through. A dedicated forum like this is JUST perfect! So thank you for that

Anyway, I'm building two new mountainbikes - one for me and one for my dad. We have decided to go with the popular and well-know CS-057 workhorse from Peter at XMCarbonSpeed.com. The CS-057 just feels like the safer choice. We are now trying to figure out what size we need and we have done some calculations online. But we're not sure if these calculated results apply to the chinese carbon frames, like the CS-057, too (I've read somewhere that they don't).

So what are your recommendations based on your knowledge and experience?
What frame size would you think would match each of us?

Here are our data...

Me
Height: 174 cm
Inseam: 88 cm 80cm

Daddy
Height: 179 cm
Inseam: 82 cm

Thank you very much!
