Top notch tri specific store. No MTB equipment - all road and tri. Virtually every aero bar made and lots of wetsuit deals. They were running a deal when I last went in that gives a free DA 10sp cassette and tires with the purchase of a wheelset. All of the people working that I talked to there race too. Their website is not great graphically - but I woudl reccomend checking it out anyway. nytro.com

cheap in comparison to other sites. - i bought a wheelset and got a free Dura-Ace casette and free tires shipped from ca to ny free they knew what they were talking about on the phone. i was happy with that. seems to focus on bikes and wheels and other components - not much for running stuff besides clothing.

Had very good experiences with Nytro.
Purchased a wetsuit and needed to exchange - no problems at all. Very competant with product questions as well.
