Any triathlon shops in Tokyo?

Hi I am going Tokyo for sight-seeing and shopping. Looking to purchase reasonable triathlon & cycling wear. I heard Pearl Izumi is cheaper in Tokyo. Is it true?

The biggest shop in Tokyo is Y'sRoad. near JR Okachimachi station.

not for triathlon but you can find pearl izumi at best price in Tokyo. a shop for real athletes.

Cheaper in Tokyo than where? We can't tell you if it's cheaper if we don't know where you are comparing it to.

I don't know of any dedicated stores for triathletes in Tokyo, but Oshman's (sporting goods shop in Shinjuku, Harajuku etc.) has a good range of sportswear and equipment.
