Easton Arc 27.5 x 30mm in just at Wiggle (at least, I just got 1 of 2 in stock) and 1 at CRC. I'm going with that in a WTB TB 2.8 rear and the Dually 45mm with Fat B 3.5 on front.

It'd be interesting to hear how you get on with the rear boxelder, you will come back and update us won't you?

And interestingly they're mounted on a new dt swiss 44mm wide rim xm551 based on my beady eye and subsequent google.

Canfield yelli screamy mk1

2.8 vee Trax fatty front, 2.8 wtb rear. 38mm light bicycle carbon rims in dh layup.

Great fun, enjoyed riding it this am in some mud. Doesnt feel any heavier. Much more comfortable to ride.

Not sure on the front tyre/rim combo. Once you get on the side knobs it really grips and pulls the inside of the bars back. Quite an odd feeling that I got used to over time.

Looks like DT Swiss have a new rim offering: (two actually but the 551 sounds good)

I'm still holding out for the Superstar ones, well actually I'm still holding out for someone close to get a set that I can borrow & try out for fit as the chainstay doesn't look to have a huge amount of clearance on a 2.25

I'll do you a sketch of my wheel measurements if you like - stoner did it for me and it helped confirm that it'd fit my frame.

Cheers but there seems to be so many different variations in size depending on rim & tyre combo I'm not guessing some might and some might not fit

Well I'm using trailblazers which seem to be a pretty standard choice but if you're set on something else, no worries.

Now I'm wondering if I could get a 26x3.0 tyre in my old Patriot. It has wide rims and tons of clearance... Would it be good I wonder?

Right had fun tonight.
Scraper rims, DT Swiss Comp Spokes on Hope EVO2's with brass nipples. NOt cheap in the end..ouch.

Rear tyre WTB Trailblazer - 2.8inch
Front tyre Spec Purgatory 3inch

Didnt fit on Whyte 829 frame as intended (chain stays weld right in the wrong spot which is a shame),

But DID fit in the Transition Smuggler with quite a lot of room to spare at the back.....All in black looks MEGA!!

Here we go.
Ride is great. No noticeable drag. The 3inch front tyre is VERY tight in the pike and has been tweaked again to try and stop it rubbing on the disk side of the fork when really leaning on right hand corners. Rubbing is only buzzing but will need some helitape I think on the top of the fork leg. Loads of clearance in the back for the 2.8TB. Loads of grip this morning on the slightly damp trails and greasy bits I found. Ploughs through mud on the bridleways we crossed. Really impressed. Will be taking it to Afan and BPW in the next couple of weeks...now that will be fun.

Any chance of measuring the front tyre at the widest point please?

Nice.

So a 3in Purg [i]should[/i] go in a Pike OK if mounted on a slightly narrower rim than the Scraper.

Thanks for the pics!

That's my plan, WTB i35 Asym rims (whenever they start appearing for sale that is) and 3" tyre. You think there's clearance for 3" tyres in the rear?

I've created a 29+/650b+ frankenbike from an El Mariachi, had a couple of little rides and all seems good and was meant to be testing it today until yesterday's stupid slipping lock on grip crash.

Is the Purgatory tyre a 650b size and where did you get it from? Had a quick search but couldn't find anything.

No noticeable drag

That's my experience too and definitely different to proper fat bikes where you can definitely feel them slower. My strava times back this up too and I've set PRs on various climbs with b+ wheels.

The extra weight though is undeniably there but whether it makes that much difference is going to be the usual subject of debate.

I think extra weight will depend on what you start from, surely?

I currently ride 2,100g wheels with tyres around 900g on my FS 29er.

There was very little weight difference for mine. Carbon rims and shorter spokes offset against the old, plus I was running pretty tough tyres in 2.35/2.4 on the 29" anyways

That 3.0 tyre looks pretty close to the fork, shame as it looks a nice tyre profile. I'm looking for another 2.8 for the front that's more uniform than the Trax fatty as it self steers too much for me. The trailblazer is really only about 2.6 wide.

Smuggler looks good

Good info cheers Alex, do you think the Vee tyre would be different on a narrower rim, with a more rounded profile?

It's on a 40mm rim and the shoulders appear to be quite steep. I think it would maybe work better on a wider rim (hugo etc) to slacken the shoulder angles. It might self steer less.

Not too many tyres out there to play with, I want to try the maxxis offering.

Out of interest what pressures have people tried? I'm 11st 3 and have used 16 psi front and 20 rear, but I might up the front to try and reduce the self steer.

Ive not been out this week to have more of a play with pressures, only a rip round the garden. It's amazing how nimble the bike feels for tight turning.

I'm more like 17st and running 15-18psi front and 20-25 rear.

Cheers nemesis.

I've had a play tonight and I found the self steer was being triggered at about 11psi, above that it was ok. The shape of the tyre appears to have changed shape a little, maybe stretched and the effects seem to be less

Nemesis, you running tubeless with those rims and pressures? Currently have same set up but with tubes (although haven't ridden yet due to broken shoulder blade 😥 ).

Charge Cooker (steel), Manitou Tower fork, SS DS25 rims and WTB TB's 2.8. First time tubeless. Was worried when the rim was leaking air on the seam on first inflation but seems to be holding well now I've added sealant and done the usual shaking like a madman! There's loads of clearance on rear but wouldn't want any wider rim on front as Tower is not so generous.

Mine leaked a bit at the seam on the first ride too. It's been fine since though. Your charge looks good though. It's amazing actually how normal it looks and how skinny standard 29er wheels look.

I went out on standard 29er wheels today to compare - did the same route as at the weekend. According to Strava there's basically no difference in speed on the flat/climbs (and again, this is borne out by several rides) - certainly not enough that you'd notice (I did set a PR by 2 seconds over the PR I set at the weekend on a 7 minute climb today) unless you're a serious racer.

I really noticed the difference DH though - It's the first time I've ridden an mtb without b+ wheels for at least a month and it felt really quite sketchy on the front even though I was riding my much more capable bike (lighter, dropper and front sus).

It's made me think that I might actually change my front 29er wheel for a b+ one permanently

That reads as if you had two different bikes, not the same with 2 different wheels. How much was the wheels and how much the bike do you think?

Yeah, two different bikes so it's far from scientific but the point is that the more capable bike which I rode today (lighter, front sus, 29er wheels, dropper) was only fractionally quicker on the climb and markedly worse on the DH.

I've also ridden both bikes with 29er and b+ wheels and again, don't notice any difference on the climbs/flat.

Again, not scientific but for me, showing (along with many other rides) that b+ wheels don't seem to be inherently slower on the non technical stuff despite perception that big tyres will be slow. Again, I think that a lot of it comes from big tyres having always been FR/AM/Enduro/DH focussed and built as such - tougher sidewalls, big knobbly treads, etc whereas b+ tyres are scaled up trail/XC tyres rather than DH style.

The real point being though, if you're a similar pace to your riding mates on 29er wheels you'll probably be much the same on climbs/etc if you switch to b+ ones, unlike say a proper fat bike which IME is noticeably slower on climbs.

My bike isn't slow I am, I was / am looking at b+ stuff for a bit of confidence at the front and cushioning at the rear so knowing that there is little performance difference gives me even less excuses to not buy stuff

I'm much the same. The point is that b+ isn't making me any slower on the bits that I'm worst on (the climbs). If I got a fat bike, I'd be getting left way behind on the climbs compared to other riders I ride with which would piss me (and them, probably) off.

Right then, the Spec Purg 3" is too much for pikes on 45mm rims. Too much rubbing. So what 2.8 options apart from trailblazer are out there with decent amount of grip?

Spec Purgatory on 45mm Scraper rims comes at pretty much spot on 80mm edge to edge. Hope that helps those who asked above

Variflex - I have Panaracer Fat B, 3.5 on 45mm rim which fit in Revs with a few mm either side. Grip seems better than the WTB TB, but side walls are light and I've not managed to seal them tubeless (not really tried properly yet). They stretch a few mm after inflation. Much rounder profile than the TB on wide rim, so nicer steering.

Thanks boxelder, also looking at Trax Fatty 2.8.

Spec b+ from any Spec dealer. My LBS got it for me. Circa £45.
Mine may well be for sale later this week if the Trax Fatty works. Will be up for £29 posted. Only done 2 rides.

I may take/swap that if it fits. I think the weight of the trax put me off.
