JB – been through this recently for my 26″ Flow Ex rims so just checked for Crests.
According to Stan’s website here the Crest rim can use a 21 or 25 mm tape. The tape in the kit you linked to is 25 mm – I got the same kit from a different website where it was advertised as 25 mm tape which is exactly what I got.
I’ve taped both of my wheels and there was a fair amount of tape left over so I think they’ll do 29er rims. Definitely follow the video tutorial on Stan’s website.
Still got tubes in mine as instructed by the video tutorial to make sure the tape has stuck to the rim properly so haven’t used the jizz yet. The only thing I’m not sure on is how much jizz to use – I think I read somewhere that the 59 ml in each bottle is for ‘normal’ tyres but larger volume tyres need more but I don’t know how much more. I’m setting up 26 x 2.2″ BC Rubber Queens (large volume) so I wonder if your 29er tyres might need a little more also? Anyone else know the answer to this (if you don’t mind me jumping on the back of your thread!)?
