Tyre Armageddon.

24 04 2016

At the end of the world, I wonder if the new Maxxis Minion 29+ will stand alone on the field of battle?

This picture, lifted from Vitalmtb, will serve as evidence to back my conjecture.


On the right, as you look at it, is a 27.5×2.4 Minion. Not a small tyre, by any normal standards. The other tyre is a 29×3 Minion.

Now *thats* what I’m talking about.

I would love this in 29. Been running the Knard and the Dirt Wizard and have not bothered with anything else. But a grippy Maxxis tire would have me opening my wallet when the Wizards are worn out.

Hi Jon…these looks very promising. I’m doing some of my own real world comparisons for various tyres / wheel sizes. 29×3.25 Dozers on a 50mm rim come out at 773mm compared to 760mm for 26×4.8 buds on a 65mm rim. I’m thinking some of the ‘larger’ 650B+ tyres may sit between these figures therefore potentially delivering the best of both ‘plus/fat’ profiles. I think I’m right in saying you’re running some 650B’s on 3.8 Hodag tyres? If so, do you know the overall diameter for this wheel/tyre combo? Cheers Ross

my hodag on a 45mm internal rim is iirc 745mm diameter. (id have to go back and remeasure – it *might*have stretched a ;little in time.. )
i believe it might get a little wider, but not taller on a wider rim. i suspect the barbegazi 27.5×4.5 will be more akin to the 770mm or so you are looking for. they are in stock in the usa – suggeest calling lacemine29.com or are due at Triton somewhat soon…
the hodag is a fantastic tyre IMO, great grip in slop and rides lighter *on the front* than the weight would suggest…

Hey mate,

I have a son28 on my 29+ wheels and I have a few questions for you, because you seemed to make it work a while back?

Did you have any issues? It wasn’t until after I had them installed that I discovered they are actually a touch bigger than the recommended diameter from SON…. Did yours work flawlessly? I have “the plug” USB and seem to be having a challenging time getting it to work fluidly.

thats disappointing! in what way is it not working? i knew they were a little bigger and anticiptaed the charging kicking in at a slightly higher speed than for smaller wheels. i use a http://www.sinewavecycles.com/products/sinewave-revolution but the hub is the same – it works beautifully. i dont know exactly aty what speed it kicks in, but i never feel like i am struggling to get it to charge?

I was wondering if you’d comment or post on your latest thoughts on internal rim widths and tyres for Scottish riding in both 650B+ and 29+ formats. I see MikeSee is very content with 35mm internal widths but like a lot of mountain biking bias – it’s very hard to separate American conditions out of praise for specific things especially if you’ve never ridden in Arizona, California or New Mexico… For Scottish 29+ and 29×2.4 use would you be content with only 35mm for day long excursions and bikepacking jaunts? Likewise for 650B+? Would 35, 40 or 45mm internal generally be preferable here?
And is the drop down to a 2.4 650b, if this is less tempting than the same drop in 29er format it makes a wider 650B rim much more a priority than achieving a compromise in the 29+ rim with 35mm or 40mm so as to also accommodate a 2.4 tyre.
Moving to Scotland soon and wishing to switch from a 29er with Flows to one 650B+ rigid and one 29+ rigid I’m now unsure of what rim widths to plump for. Easton arcs come in 35, 40 and 45mm internals…
I ask as your combination of wheel sizes and bike stable are very much what I admire.

morning! it is a good question! i think for a full 3″/75mm wide tyre a ~50mm external/ 45mm internal is great, but not necessary. the narrower rims (from 35mm external/30mm internal and wider) i have used have a very similar feel with the tyres I have used. with the current crop of 2.8 650b tyres i wonder if 45mm external/40mm internal might be the sweet spot. i have a carbon rim bias – mainly to reduce weight and this allows me to choose width with less penalty, for aluminium, i think the DT swiss XM 551 rim is pretty spot on. i wonder if the wider rims promote more rim strikes – if the wheel is leaned over and the tyre compresses against a rock, there seems like less distance from rim edge to ground to me and the plus tyres tend to compress in a more linear fashion than a thinner tyre. in saying that i have not had any rm failures on plus bikes yet…as for plus use in scotland – until it is very wet and sloppy i think it is great. the more natural trails here have a lot of ‘buzz’ from rocks and rough ground that (at least on rigid bikes) is removed by the lower pressure tyres. in sloppier conditions a narrower tyre cuts through more easily. the plus and fatties can sometimes shear on the surface when it is very sloppy, so sometimes i prefer 29ers – but with slightly knobbier 650b+ and 29+ tyres imminent this may be less of an issue soon! hope that helps!

[…] take advantage of the slightly longer front centre and increased offset. Until the new crop of more aggressive 29+ tyres become available, I may put it in the shorter offset position and see how that […]
