Just wanted to post my Pivot Mach 429 Trail, loving it so far. Its an extremely fast pedaling bike and surprisingly light in a plus setup.

Medium, XX1 Build - 27.5+ wheel/tire
Wheels are Ibis 741 Carbon, 35mm internal
Tires are NN 3.0F (trail star) and 2.8R (pace star)
Weight: 25.3lbs w/o pedals

WOW, that bike is sick! Just add dropper (even though it'd add a pound) and it would be the sickest, most awesome bike in this whole thread, hands down.
Thanks for sharing!!

Thanks for the compliments! Ridden w/ droppers, not sold yet for my style, but we shall see. I can change opinions over time and add it easy enough. Here's a couple pics of the rear clearance.



 
Decided the length on the Ragley wasn't doing it for me, so up for sale the frame goes....

In it's place is my new Bird Zero AM. Advertised as taking 2.8" tyres.... It is still fairly tight on the right I'd say even with my Nobby Nics.

Just finished my 2014 SC Heckler. First ride this morning to work with a slight detour :)

It's size XL, Yishun carbon wheels 35mm internal width with DT Swiss 350 hubs, 2.8 Nobby Nics, XT/Raceface/Absolute black drivetrain 30x11-42, X-Fusion Sweep 27.5 RL2 fork. A dropper post will be added when I can decide what to get.

I just love the color of the bike.

bet thats a snug fit between the stays yes?? tis a sweet color for sure.
 
Hey Everyone!

What I would like to accomplish by this thread is a central place for guys and gals to post what rim and B+ tire options they are running on their standard 29er bikes.

I know there is a lot of pics and posts out there concerning B+ platform compatibility, so lets get it all in one place.

Please include pics of your setup.

I will start off.

I have successfully run the 650b Velocity Blunt 35 rims with TrailBlazer 2.8 tires on my Kona Process 111.

Please post your setups! If you can include measurements and clearance pictures, it would be even better :)
Is that a regular fox 36 650b fork or did they start making a 650b Plus version?
 
(Posted this in another thread but thought I'd share it here too)

I'm on my way to trying out the NN 2.8 on my SC v2 5010. Trailstar front and Pacestar rear:



I put the front in my fork (a standard 27.5 Pike) and it fits no problem. Plenty of room.

The tire, mounted on a Nox Farlow with id 29mm, measures 715-716mm tall and 68mm wide.

For reference, a Conti TK 2.4 is 712-713mm and a WTB Vigilante is 711-712mm. These are taller 27.5 tires, so the NN 2.8 is very similar in height, though of course wider. Other typical 27.5x2.3 tires are closer to 705-707mm.

So the NN 2.8 -- as Ibis has been saying -- is MUCH closer to a 27.5 tire in height than a 29er. In fact, with the lower pressures that are used, the height is actually equal once compressed. Width can obviously vary a great deal based on the rim. Mine of course are on the narrow end of what can be used with these tires.

^^^This looks to be accurate and is probably why Ibis saw this opportunity to create a bike, the HD3, (with boost rear) to capitalize on this reality. Its also why the Hightower was made for the 29er market.... 2 bikes in one concept. If you honesty want to stuff a tire/wheel (i30-i40 rim) into your run of the mill stock 29er, then you are looking at a 3++ inch tire to do so. I tested this out mine with a VTF 3.25 which measures just a touch over 29 inches....NO bueno! Also, most run of the mill 27.5 bikes cannot take the larger 2.8-3.0 tire/wheels, because of the lack of rear spacing. Enter boost and plus bikes that are now MADE for the mid size plus wheels blowing up! There is a compromise converting either a 29er or a regular 27.5 in geometry and handling. It can and has been done, just not without changing the intended stock specs of the original bike. Still great to experiment with what you have and see what can be done without actually changing frames. More tire and rim options make this all posssible so bring it ON! :thumbsup:

I disagree with some of this and it's not all accurate.

What I think I showed - and what Ibis has written about at length on their site - is the NN 2.8 does NOT change the geometry of a 27.5 bike. It most definitely does with a 29er.

Most (all?) 27.5+ tires are different. They are, I'd argue, meant for converting 29ers to plus bikes.

it's all about choices. Most if not all fans of wagon wheels either know this or will in short order. You could debate/argue sure enough but why?? it yields you nothing to prove or disprove what was meant by the design and release of 650b+ rubber.

I'm neither debating nor arguing. I'm simply trying to offer some information as someone who has actually measured these tires. And measured them against several 27.5 tires.

I'm strictly referring to the NN 2.8. The range of 27.5+ tires is evidently very broad and sizing - width and diameter - runs a huge range.

My point is the NN 2.8 is more of an alternative tire to those of us with 27.5 bikes. Or 29ers like the Hightower that have chips to alter geometry.

If you're going to run a NN 2.8 on a 29er you're going to find your bb is too low. You are essentially putting on a tire with the same diameter as a standard 27.5

would these measurements be on the same rim or one that plays to it's strengths? meaning the NN 2.8 is optimal on a 35i rim VS a 2.25 tire on a 22i rim. The width/girth of a 2.8+ tire is it's forte as opposed to overall dia, hence the appropriate rim width is necessary to really see what the plus movement is about. Sure brands differ which skews the market but then other regular sizes have suffered this for what is decades.

I am going to disagree too :)

Putting plus tires on your bike does not change the geometry of a 29er, 27.5, fatbike, etc. It will, however, lower your bottom bracket height. This is different that changing a bikes geometry.

Not trying to split hairs here, but there are others that might get confused by your statement.
 
Well, I disagree with you both, because once you change one geometry number (yes, BB height is one) then you've changed the geometry of a bike, effectively you've lowered the centre of gravity, the bike must handle different ;)
