This 29+ thing...

[Ian]

I'm thinking ahead to the HTR560, and with half an eye on a Revo which will require a new wheel build, I'm considering 29+ as a replacement for my suspension fork. The overall weight should be less than with a fork, though rotating weight will increase, which I'm generally ok with as the increased inertia helps roll over/ through stuff.

Any 29+ size wheel users on here willing to impart their experiences so far of larger diameter wheels?

Specifically, I would like to know what rim are you using, and how do you find the weight and rolling resistance of the tyre? What pressures do you run? Is it set up tubeless?

Options for rims seem to extend to:
Rabbit Hole (heaviest and most expensive)
Velocity Dually (lighter, cheaper)
Velocity Blunt 35 (narrower, lighter, cheaper)

Anyone have any views on these?

Cheers,

Ian

Not ridden one but there are also the 47mm (iirc) Northpaw rims that Travers use.

[ScotRoutes]

How tall are you?

[Ian]

Northpaw, thanks I'll check them out too

I'm 5' 9", but with long legs.

Edit: like the Northpaw rims. Did see them when Stu tested the Travers, but forgot about them since. Seem to be the lightest but most expensive option.

[johnnystorm]

Thinking about those northpaw rims.....they're about £130 each (gulp) and ~75 gms lighter than a Dually. If you're going tubeless I doubt there'd be much in it once you've plugged all the holes.

[Ian]

That's a good point...

A few more rim options, all wide enough to take a Knard.

47mm Kris Holm Freeride rim, 780g £56: http://www.unicycle.uk.com/unicycle-par ... e-rim.html

42mm Nimbus rim, 903g £39.50: http://www.unicycle.uk.com/unicycle-par ... ator2.html

38mm Kris Hilm XC rim, 830g £38: http://www.unicycle.uk.com/29-kris-holm-xc-rim.html

I have run a P35 and RH on my Krampus. I find the p35 gives a more rounded profile to the knard and it seems to roll better, I quite like it on woodsy single track. For absorbing bumps and down right grip it has to be the RH and is my preferred set up.

In hind sight I think I should have gone dually's for ease of setting up tubeless, but I preferred look of RH. Stan's are supposed to have a 50mm rim in development so may switch to this when/if it comes out. I have seen guides though on how to set up RH tubeless and think I am going to give it a try. Although there seems to be some debate on mtbr as to whether it is of any benefit (manly due to risk of burping on RH and ltd weight saving).

Your probably well aware of this Ian but don't run the surly 29x3.0 tubes. They weigh over 500g each! 29er tubes work fine and are half the weight

Pressure wise, I run 15psi on the p35 to give a nice fast rolling tyre (any lower and they squirm) on the RH I find 13psi to be ideal. I find they are very sensitive to pressure changes and change of 2-3psi makes a huge difference to how the tyre behaves. For references I am 5'6" and 10st

I have a pair of dually rims on order from the good folk at keep pedalling.
Once they arrive and I build them, I'll be taking the sus fork off the salsa and using a travers fork.

It's unlikely for me that I would use this set up on the htr but you never know.
I'm using a 2.3 tyre normally on the front and will of course be fitting a knard.

I'll let you know how it goes.

Edit.
I intend to run the knard on the front tubeless and see if a 2.4 ardent will fit in the back. Either that or a 2.3 spesh ground control.

[Brothersmith]

I use 2.4 Ardent on a P35 with niner fork on my Fargo for bike packing duties works really nice for taking edge of the bumps. Think a dually and an Ardent would be a real nice combernation.

I found a knard give me toe overlap and kicked the front end up too much for my liking
