i am going to get the IRO-Mark V and was seriously considering the $100 wheelset upgrade...so, do you think this decision is definitely a smart one? i think it is...i just don't know much about wheels and this wheel has machined sidewalls which i know is a selling point for some but to me i don't care about the extra braking performance. basically is it a good deal for a fixed gear wheelset or should i get the bike and get a different wheelset? haha damn this was longer than i had planned.

p.s. is the stock wheelset strong enough to ride on for a while until i save up enough for a new wheelset... if i don't get the deep v upgrade?

Yes, the stock wheelset is a very nice setup. Plenty strong for all but the wrost abuse. The Deep V's have a reputation of being bombproof and they are, but if you are tight on the money right now go ahead and get the stock build and have no worries.

Their stock wheelset looks pretty good to me as it is...
