    Beargrease w/ Bluto 29+ clearance?

    Getting a summer wheelset and cant decide between 27.5+ and 29+. From the pictures, it looks real tight but fits. Salsa even says up to 29x3 but how close is that in reality? I once

    Once went over the bars when a front wheel wedged a rock into my RS Reba crown, so a little paranoid of squeezing in a tire with 2-5mm clearance. Any thoughts or setup comments?

    I ran 29+ with a Bluto at one time and don't recall any issues. Clearance on my Wren is fairly tight as well (Wren actually recommends adding a 10mm travel reducer for more crown clearance, which I didn't do), and haven't noticed any issues including some hard bottoms. However my Minion doesn't seem to really grab rocks either so YMMV.

    However, if possible I'd suggest 29+ over 27+. The rollover is unbelievable. Similar to fat tires, but way faster.

    Frame fits 29+, Bluto fork is tight, depends on tire choice, I rode mine with a Dirt Wizard it wasn't good for mud or rock clearance. Lauf fork fits 29+ and 26 x 5, as does Mastodon.

    27+ would be more agile, but you'd be hitting your pedals a lot.

    Yeah keeping my BB height the same is a big priority. I ride 4" JJ. Maybe a Trax Fatty 3.25 b+ could keep the same OD

    If he ran 27.5"x3, I don't see how he'd be pedal striking any more than normal. Aren't effective diameters roughly the same 27.5x3 and 26x4?

    I have 27.5 x 3 tires (Specialized Purgs and Schwalbe Nobby Nics) they measure 28.5" tall, Jumbo Jims 26 x 4 on 65mm rims measure 29" tall.

    ^ wut he said.

    Low is a relative term, my fs bike (Hendtix) is low and I pedal strike constantly, but it rides great downhill.

    There will always be a compromise when you use different wheel sizes than a bike is designed for.

    The Beargrease with 29+ is fast and flowy, but it's not agile. If I was looking to put down miles, bushwack, bikepack, I'd go 29+. If I wanted a trial bike for techy stuff, something playful, I'd go 27+.

    Another advantage of going 27+ is you can run "fat minus" like the Minion 3.8, also future sizes in 27.5 like 3.25-3.5

    Since the Beargrease is already a bit long in the tail, 27+/27 fat minus would be my choice; that's how I run my Wozo.

    With 27+, also consider running a 120mm fork, which would slack the steepish head angle and help compensate for the low bb

    Yeah I like flowy trails but most here in CO that I have access to are not. I really just want aomething that rolls faster than 4" JJs which is why i started this search. This is my only MTB, so I want to make it count. I think the 27.5+ should meet my needs even if I sacrifice a 1/2 in in BB. Im open to suggestions on alternate 4" tires too like maybe 120tpi HuDu but not sure anything 4" is goong to make a difference compared to the JJs

    A 27.5+ on a bucksaw will probably be a higher bottom bracket than many bikes out there. On the other hand I have 65mm LB rims with a wheel set that weigh 1600 grams. JJs on these wheels roll as fast as my 27.5 x 3 wheels.

    Nah, 4" tires are slow and handle akward, esp on a hardtail. If this is your only bike, build a set of 27.5 with a 45-50mm rim (Duroc is my current fav), then add some 3" tires for summer.

    Come fall, try some Minion 3.8 if the JJs are too sloppy.

    I think thats the plan. I run VanHelgas in the winter. Never liked the JJs in the snow, at least when turning... at all.

    I've liked my mulefuts, so Im sure the duroc is a good wheel, but honestly hadnt heard much about them, although I just started looking in this range. Had luck with Hope Pros, so might try the fatsno.

    Thanks for the input all

    +1 I'm running JJ's 4.0 on 65mm Nextie's and they are light and fast. It is the only wheelset i have currently for the fatty but it rolls much faster than either of my 26'r hardtail or FS.

    I'd consider a 650B or 700C wheelset but not until i have an 80-85mm and a 100-105mm wide wheel sets first. But that's just me, YMMV.
