Hi guys,

1. Has anyone got the ERD of Mavic 819 Tubeless rims (need to build some up)? I can't seem to find details I trust on the web.

2. Also, anyone have experience building these? I assume that it's just a bit more time consuming (nipple carriers etc). Any tips appreciated.

Thanks,

Josh

There are two entries for 819's in SpoCalc.

One is for an "XM 819" and it's ERD = 534.5mm and the other is for "XM 819 Disc" and it's ERD is also 534.5mm. As always, Mavic rim ERD's in SpoCalc are "Nipple Seat Diameter plus 3mm for nipples".

SpoCalc's database gets pretty well scrutinized so I'd say it's good to use. Once I started using it I never looked back. You can download it for free from this link:

You will need the 16 mm nipples for the build. Be sure to use loctite(blue) on the eyelets and let it cure up a little before you start turning nipples so the eyelets don't unscrew.

Cascade and Reverend,

Thanks a bunch. Sapim advised me of the 16mm nipples, and I heard a rumour about the loctite (the suggestion was GREEN loctite - but I will go with BLUE based on your recommendation).

DT Swiss online spoke calculator claims that they are 538mm (which fits with your 534.5mm + 3mm perfectly) so we're cooking with gas!

I too am a spocalc disciple (it's never let me down) but for some reason could not find the 819s in there.

Thanks again. If I remember, I'll let you know how the build goes:

819s
Hugi 240s Centrelock Front
Hugi 240ss Singlespeed Bolt-on Centrelock Rear
Sapim Race Spokes

Should be a killer wheelset, but it's a pity it's not mine!

It's funny .... I looked at the DT Swiss Calc and did not see them ;-)) When I was looking in SpoCalc I was wondering how you update the database. I guess you just have to periodically download a new copy to have all of the latest updates.

It's always nice to have two sources.

Good luck with the build!
