Let's see your 29+/650B+ & other "Nearly-Fat" Bikes

Here’s the new set up…

The Alfine was faultless, easiest set up of any gear system I’ve used! Fit the wheel, hook up cable and take up any slack with the barrel adjuster. Easy peasy 🙂

I used a Paccenti DL31 rim (currently £40 at On-One), Sapim spokes, and used a 2 cross pattern due to the large flanges. The Knard went on the 31mm rim easily. I know Surly say a minimum of 35mm, but I didn’t have any issues at my normal pressure of about 15 psi. If anything the fact it made the tyre profile rounder meant that it cut through the slop a bit better.

Lovin’ the Stooge with the fatty up front Kbrembo. The trail look great too, where is it?

ajantom.
Alfine sounds great hope it holds up well.
I’ll consider building one onto a 650b rim for the rear end of my Stooge in the near future.

Maxxis Chronicle users, what tyre pressures are you running?

on one carbon forks which have ‘just’ enough room

Which forks? 29er or Fatty?

I’m running the on one monocoque fork with a Dually rim and there’s maybe 4-5mm each side to spare. It clogs a bit now that the mud fest is here but I’m not too bothered by that. The Chronicle should be here by the end of the week so the fingers are still crossed. In an ideal world I’d maybe go for their new FAT fork or if money was flush I’d go for the Niner ROS9 carbon fork which I believe has a little more room to play with.

It’s a third hand ‘hand-me-down’ Knard so it’s balder than Kojack! As such it’s not the most confidence inspiring when in deep mud but then again I’m struggling to think of a tyre that is. On wet roots / rocks I’ve not had anything that rattled me too much. If it does slip on something then you’re usually over the obstacle and onto firmer ground by the time your sphincter starts twitching.

Anyone actually put a 650b+ Trailblazer in a Ti Spaceframe? I dont know if the (pre 2014/15) Steel is the same clearance as the Ti spaceframe but I’d like to put a b+ tyre in there. On paper it looks like yes, I just wondered if anyone has tried it?

Chainline – how’s that? DrJon’s bike, pic from his flickr page. I’ve offered the Trailblazer on a Scraper rim up to my spaceframe and there’s enough room. Some pics of a SF with them fitted F+R on MTBR also.

Jones steel spaceframe 29plus front wheel.

I want to fit a Knard on Crest to my Singular Swift (old blue one). Clearance looks tight! Has anyone tried this?

I don’t think a knard on a crest is a good idea, flow-ex width seems to be about minimum for a knard.

Spacewise in the fork I also think it would struggle.

Sam had some 29+ forks knocking about, email him to see if he has any left.

I don’t think a knard on a crest is a good idea, flow-ex width seems to be about minimum for a knard.

You need at least 25mm internal rim width really to get the most out of 29+ tyres, ideally 35mm or more.

You might get away with the fork clearance, or if not most of the newer rigid forks coming out are now 29+ friendly. A Knard on a 50mm rim fitted no problem on the front of my old Charge Cooker rigid…

Anyone got a full fat front on their Krampus, was pondering this option whilst out in the snow the other day?

It’s an interesting idea Bigdugsbaws. I know a local guy who runs a fat front on a Jones Spaceframe and it certainly doesn’t slow him down 😀

Sold on the Grey Karate Monkey frame set, bought a used Pugsley frame set, offset the Krampus wheel set adding a 135mm Surly hub up front, an On One 100mm square taper BB, and now running 2.5 Minions both ends with HUGE mud clearance until i get another pair of 3″ 29+ skins, and i can also add 4″ fat wheels when needed 🙂

Mo Stooge. Widelightning rims, Chronicle front Ardent back. Ace.

Anyone fitted a 2.3/2.4 “normal” tyre on a Dually rim…
Ardent/ Ralph/Nic/Dampf
Keen to know if they get any wider or just flatter.

Early days, but anyone looked at 650b+ yet ?

Very nice ride Mal-ec 😀

They come up wider with a full profile (see the rear tyre on Mal-ec’s phot above). They lack the volume and floaty feel of proper 3″ 29+ tyres though.

2.4 Ardent on a 50mm rim on the rear of this.
Comes up much bigger than it did on a Flow.

Interesting to see that (nearly) all these steel frames are running 1x drivetrains. To my eye having a single chainring just looks right on a steel frame, elegant even.

Just going to leave this here…

24×3 up front.

Also just going to park this here:

29er Inbred, 80mm Reba 29er fork, 26×3 upfront

There’s always someone … 🙄

24+ & 26+ shouldn’t be excluded.

This is a friendly inclusive forum 😉

I can feel your love

24+ and 26+ are very welcome, it’s all about tyre girth not diameter 😆

This may or may not be of interest but I converted my Dually/Maxxis Chronicle set up to tubeless last night.

Very easy, track pump, 2 wraps of gorilla tape, bit of sealant and they went up first time.

Somewhat annoyingly I think this will be up for sale shortly 🙁

Does anyone still use 26+? What’s the general consensus?

I’ve been in Southern Bavaria the past few days, and on Tuesday borrowed a fat bike and went for a ride with a mate in the proper deep snow.
Being a bit critical of them, I was really hoping not to like it…
…but…
It was a lot of fun, but we were riding down the side of a mountain on a trail which was up to my knees in powder. That doesn’t happen often if you live in SW England like I do, so I certainly wouldn’t have a full fatty. It got me thinking though… I have access to a 650b frame with sliding dropouts, which can also accommodate a 29″ wheel, would a 26+ fit?
The following day I was chatting to a dude who had such a set of wheels (26″, 50mm rim, and 2.8″ tyre) so we tried it, and it fitted with bags of room to spare. Could possibly even go 3″ wide.
I was really hoping it wouldn’t fit, so I could put the idea to bed. Now that I know it fits though, I think I’m gonna have to get one…

Go on then. Intention is that it will have a Travers Prong fork & LB 38mm carbon rims, but that could be ages away. Here it is prior to me recording my slowest ever time on the climb back home.

any excuse 😳

^^^ Now that looks like serious fun ^^^ 😀

Transforms the feel of a bike like the 1×1 and makes my 29ers redundant.

Also pretty good in light snow.

^^^ Love the paintjob on your Surly 1×1 Epicyclo ^^^ 🙂

What’s the framebag you’re using?

cupra – 3″ tyres in a Longitude?
Much clearance?

The paint job appeals to the long lost petrolhead in me. 🙂

Framebag is a cheapie from eBay, about £15. Seems to be holding up ok, and amazingly waterproof. I’ve left the bike out in some howlers and expected to find water in the bag, but no sign of it.
