[frame sizing] Stevens bikes frame size
 

I'd like to buy a Stevens Aspin (www.stevensbikes.de) Road Bike and I'm not sure what frame size is right for me. I'm 182 cm tall and my inseam leg lenght is 86 cm. I thought of 58 cm frame, but i'm not sure it it's right. On the manufacturer's web page these frames are described as having "soft sloping design". Could anyone roding Stevens tell me whether 58 is fine or should i choose a smaller one.

All the best,

Lechu
