26" rim diameter is 559mm and 650b rim diameter is 584mm (measured at the bead)

 

I don't believe that those are the relevant measurements for the purpose of this geometry discussion however (as those are approx 22" and 23" respectively)...the relevant measurement is the diameter of the tire.

 

Yes, and then you add to that the width of the tire, 2" back when MTB got popular and 2.25" when 650b was relaunched. 22+2+2=26" ; 23+2.25+2.25=27.5". So if you change your wheels from standard 26" to 650b, but use the same tire width you will get a 0.5" higher BB (assuming unchanged AC-length on the fork). Naming wheelsizes with reference to the outside diameter of the tires is a good way to create confusion

 

Is anyone running their hdr 650 with wide (30mm+ interior) rims?
I'm thinking about a pair of the LB wide hookless rims but i've heard differing views on whether the wider rims result in a wider tire, or just more volume. Right now i'm only running the neo motos on the back (on flows), so there's plenty of room, but i'd like to still have the option of going with a beefier tire in the future.

 

You should be more than fine. I belive Ibis says all true 2.3 tires fit fine. As for the rim, I'll be running them hopefully pretty soon.

Waiting for my customized BOS vipr Shock (216mmx58mm), I ride the Fox shock. Not so bad !

The LB rims are really great ! I love them ! Laced with CRay Spokes and Chris Kinh hubs.

 

yep, we have another 650b HDR with 2.25 Ardents. They are slightly roomier but not much. the 2.35 NN fits great.

I think all the hubbub was started by someone trying the 2.35 Hans Damph. I'm running that up front, and it's really a 2.5+. It's tight inside my Pike even.

 

Yeah I mounted my WTB Vigilante on the rear just to see if it would fit (which it did). I didn't try bottoming the fork through so i'm not sure if it would buzz the seat tube or not. The Vigilante is a very tall tire--mine measured 28.1".
That said, i like it a lot on the front, but it's just too slow on the rear.

@Covy--are your LB's the 35mm wide hookless ones or the regular 30mm version?

Pete,

I hate you.

That looks utterly superb and I'm thinking about how I could do similar outside Sydney.

For sure, must be loads of great riding in those mountains! I've got a few more rides I'd really like to do while working up at Mt Buller.

 

Very impressive of Bikeco shock and chromag moon saddle !!

 

BOS VIPR 216x58mm 650b wheels
travel : 145mm

 

NICE!!!!! I have the Deville 26' 160 on mine, (w/27.5) is yours the 650b version? is the vipr custom tuned?, so nice!

 

also any feedback on the viper would be appreciated, v/close to pulling the trigger on the bikeco shock.

 

My Deville is a 2014 650b/160mm
The vipr is the one i had before on my HD160, custom tuned to get 145mm of travel.
It's great !

 

Did you get BOS to custom tune to 145mm? Or someone else?

 

No, not BOS.
Someone else, novyparts. www.novyparts.com
This guy worked for years for BOS MTB.

 

Covy
Is your Bos vip'r still 216 eye to eye length? with 650b wheels does your BB feel to high? I'm running 650b front with 26" rear vip'r 160mm.

end of another great ride on the Mojo HDR

 

My Mojo HDR 650b - 26" build.

12,45kg (27,5 lbs) as in the pictures.

 

Looks like some of the text went missing. Anyway, I'm riding my HDR in 650b mode with 26" wheels. So far I'm loving it, the low BB doesn't bother me. Still haven't decided if I'm going to go full 650b or 160mm 26"...

 

If anyone is in the market for one, I am selling mine. PM me for details. Pics have been posted in various threads.

 

Just got done with 4.5 amazing days of riding in Sedona. This place lives up to the hype. Hit all the biggies, Hiline, Hangover, Hogs, Mescal etc. These trails are fantastic, so damn fun. So much great technical riding. My favorite stuff!

No driving, just doing big loops from town. Shortest day was ~22miles or so. Sedona miles are not regular miles! :thumbsup:

Was on the HDR650b every day, all day. I love this bike so much. It takes every last bit of the ChunderTech and laps it up. Pulling some of the moves on Hiline and Hangover most definitely require total comfort and confidence in your whip. Happy to say that both rider and bike were on. Didn't have the nutzak to try the White Line, sometimes being a parent has to take precedent!

Here's a shot on our way back to Teacup trail by the big sinkhole...

My Build:

HDR650b - stock XX1 Group
30 front ring
XTR Trail brakes
Pushed Elite Kit Float 34 - 150 (Love this fork, no Pike necessary!)
Pushed Float shock - Amazed at what they can do with this shock.
KS Lev
Ibis stock wheels (waiting on LB/King wheels)
Nobby Nic 2.35 front
Ardent 2.25 rear

~27.75lbs

Nice! I'm finally taking a trip home after a year and a half living on this island.... Any who I'm really wanting to take a trip up to Sedona and using the time share. Did you do any guided rides? Was it pretty easy to navigate around?

 

One bad *ss ride. Sweet. I'm curious now about a pushed Float shock. I have the Pike, maybe I need to tune my Float.

 

Thanks Kaj! I was considering the Pike, but the stock 34 and Float CTD were not too bad (2014 kit) out of the box, so rather then blowing a lot of $$$ to go Pike I sent the stuff to PUSH and got both 110% dialed for me at around half the Pike retail. I've had PUSH do enough work on Fox stuff that I know what I'm getting will be just right.

Not dissing the Pike, but these are dialed. :thumbsup:

 

What's the BB height with that set up?

 

You're talking about mine? Good question, never checked! It's likely not too far from stock, but with the 150 fork and NN 2.35 ft tire, it'll be a bit higher then stock.

...and FWIW, Sedona is definitely a place where having a slightly higher BB will serve you well! Plenty of opportunity to tag your pedals, even with careful timing.
