Have you contacted Ironman directly. I just got a new 13t for the front from them. Called them up and was in the mail the same day and had it in 2 days!!! Great service!!!
+1, great stuff. Had a 50% coupon for front and rear I got back in Nov. Just put them on the day before a race on April 12th. Very cool guys to deal with on the phone.
Are these sprockets really that good , nobody sells them in the uk which is a pity , I use a supersprox rear on mine , but they are having supply problems due to russia invading the city where they are manufactured , or so I was told .
