650b+ (and other plus sizes if you like) – rim, tyre, frame, fork combinations,

nice selection of plus sizes in the bike shop today, good to see someone actually stocking some

Looks like Maxxis have come up with the goods. 2.8in and exo casing, tread pattern looks good on the Rekon here…

Hopefully they won’t cost £90 apiece.

Rekon will be on my shopping list!

Right, first post, my build is work in progress (rotors and cassette to add), but just managed to fit B plus set up to a bizango frame no problems and get to run drop outs at shortest setting (can’t be done with 2.4 x 29 conti). Just trying B+ for comfort really and hopefully keep playfulness. Not gonna get ridden for another week… will report back. 2.8 trailblazer rear (on superstar DS25) with ~4mm clearance either side of chainstays, 3.0 Purgatory front (on Roval 29mm ID rim). Plenty of space in Suntour Epicon fork. Profiles of tyres look great to me, but as I say, yet to ride. I will attempt to attach a pic…

That looks good. Will be interested to hear how you get on with the rear as I found that sort of clearance a bit tight for my lurcher.

Anyone tried 650+ in a Lynskey Ridgeline? looking to give a 2010 frame a new lease of life…

WTB TB on a 30mm rime easily fits the rear of a SC Tallboy Mk1.

Looking further up the thread, alexh has kind of covered this (in fact I copied you, cheers dude :D), but WTB TB on Blunt 35 rim fits with room to spare into a CB Yelli Screamy, despite CB themselves saying it’s “not recommended” on their website. I probably have 6-7mm each side with a slight dish offset.

Also squeezed a Vee Trax Fatty 2.8 on Dually 45mm rims into an X-fusion trace. Although clearance on that is 4mm and shrinking. The tire seems to have grown on todays ride.

Just wish I’d gone for carbon instead now, the light bicycles stuff is barely more expensive than ally. Buy right or buy twice as they say

Rich, nice yelli! Thankfully I wasn’t doing it off my own back. My lbs built up some rims for me to try and assess clearance. Tyres do grow a touch, my vee has stopped thankfully or I’d need new forks!

That depends on how long the carbon rims last! Touch wood they are ok for now and I did go for a stronger lay up.

As its been dry all week I dusted off the full sys and I didn’t ride mine today. I missed it.

I’m going to try the bike with a 29″ front slapped back in.

richw927, what does the Trailblazer measure at on a 35mm external rim?

I’m assuming here that those above talking about 30mm rims are also talking external width.

Cheers alexh! Was a lucky spot on Pinkbike, so impressed with it. My Vee tire is another story though, on any surface that’s slightly dry or hard it just feels unpredictable. Will play around with different pressures I think. Have you settled on a pressure that works well? I’d almost say it might work better with TB on front and Vee on rear. Has anyone tried that?

Ctznsmith it’s in the shed at the moment but I’ll have a measure and post it ASAP

Yes Vee Trax Fatty almost self steers on tarmac. Ok on everything else apart from hardpack. Im running it at about 10psi on 45mm rims. Waiting for the Maxxis Rekon+ as I reckon that will be a perfect replacement.

Same here, waiting for the reckon to replace the trax fatty.

I’ve found it steers less above 15 psi. I’ve ran mine a touch harder of late and I’ve not noticed any performance issues. I’m not brave enough to try 10 psi on the carbon rims with how I ride

Ha, maybe I’ll try around 10 so I can bin my rims and get some carbons! Hopefully there’ll be a lot more choice in 6 months, when hopefully the trax will be worn enough to warrant changing. Schwalbe RR and NN are definitely on the horizon.

My TB is approx 65mm wide on a Blunt 35, at approx 18psi. Thats by eye so may be a mm or 2 either way.

anyone bunged a wide rim and + tyre in the back of a kinesis FF29?

I meant a real person who can show the tyre clearance not a showroom side picture

I hope they have sorted out the clearance issues on the ff29 running 650b+, saw one at a race earlier this year and mud clearance was non existent, yes the tyre fits in the space, but that was about it.

@richw927 @alexh – what’s the current best practice on a mk 1 Yelli? What rims/tyres have you been getting away with while still having a little space for leaf muck etc. I need a North Downs winter reasonably viable setup (tho actually I spend most of the time on the Greensand – Leith Hill, Pitch, Winterfold etc).

My email in profile if you’re OK to chat.

Ta. Up the Yellis!

matt.
Be aware that very early Yelli’s have very little room for a B+ tyre.
Later mk1’s are ok and mk2’s are fine.

I’m not enjoying the cornering lack of grip on my trailblazers with lb 30mm id rims. Might try a spec purgatory in the front with my Reba. If it is tight on a scraper in a pike, I hope I will be ok. Anyone done similar yet?

ssstu thx, mine is a late 2012/early 13 I think, serial start P12. (I bought 2nd hand spring 13 but it was pretty new). A Trailblazer goes on OK on a Flow, but really a wider rim is needed to make the best of b+ I think so trying to figure it out. (have mailed Canfield to see what mine is).

The later mk1s will fit a trailblazer on a scraper with very minimal room.
mk2s have a little more room.
After todays muddy ride i’m either going for a narrower rear rim or sticking 29 wheels back in my mk2…

yeah I’m thinking Scraper isn’t going to fly too. 30mm internal might.

there were enough benefits just on a Flow that I want to find out more.

I’m using a light bicycle 38mm rim with trailblazer rear and vee track (both 2.8). My yelli is a mk1 but 2013. Mud clearance on the rear has been fine so far. The trailblazer having no tread on the side doesn’t appear to hold mud on the sidewalk (the main pinch point to the stays in the rear).

I’m going to build up my 29″ wheels again

2.8 Trailblazer on 45mm Dually, in the back of a SIR.9
(Not exactly known for big clearance).
Was fearing it wouldn’t fit but runs just fine.
(No tape hence ghetto, & not got round to trimming yet).

@alex thanks, don’t suppose you’re anywhere near Surrey Hills are you? (I think I ‘probably’ have a later Yelli Mk 1, but it could be an expensive mistake).

@taki wow good result, and it’s refreshing to see a different pic of your SIR9 after all these years.

Anyone “plussed” a Singlar Buzzard yet… Looks like masses of clearance on my new s/h frame, so am fairly confident it will be fine?

@cheezpleez has a Buzzard, I’ll nag him.

Sadly not, Midlands based.

Doubt you’ll get Spec 3″ tyre in Reba’s. I’m told they measure up correctly at 80mm+ – someone on here was selling one for that reason.

I’d agree with that – my 64mm wide Trailblazers fit fine but there’s only 5mm or so clearance either side.

I’ve got a Panaracer 3.5″ FatBnimble in Rebas (measures 72mm) but wouldn’t go wider.

Anyone plusssed a Merlin made Jones Sapaceframe?

boxelder – what rim is that on?

Nemesis – Dually 45mm.

p.s. – those forks working out for you?

Yeah, no issues with my wheels in the Reba.

I meant are the ones you bought off me working OK?

😳

Oh, right, yes, they’re on the other bike. Only ridden them a few times but they seem fine after the service. 🙂

Anyone plusssed a Merlin made Jones Sapaceframe?

No but i’ve had a Trailblazer/Scraper combo in the rear of my steel spaceframe.
The steel spaceframe has a tad more room than my old Merlin/Jones.
