    Calling 907 owners - BFL

    Does anyone think the BFL will fit the Alu 907?

    If it was designed to work with a 100mm rim & 3.8" tyre would a 65mm rim & BFL work if running an Alfine hub? Hmmmm...

    TBH, I think the frame will be a little tight at the chainstays myself, but Im just considering some options.....just like the rest of you!

    Mine's in storage so I'm absolutely no help, but have you thought about a BFL up front?

    I'm wondering if one will fit in the Pugsley forks... I have Large Marge rims so I think one might...

    Maybe on 50 or 65mm rims, but at least on the earlier AL frames I doubt it. They were pretty tight with 100mm rims and Endos. Later production runs may have had more room.

    My 907 is 2011 model and I'm pretty sure that BFL won't fit. 100mm rim with normal 3.8" Larry is probably the maximum. I have a set of 80mm Fat Shebas and I'm hoping that the new 45NRTH Husker Du 4.0" tire would fit though.

    But for the most of current fatbike owners a fatter front should be possible with the BFL. I measured my Salsa Enabler fork and there is about 120mm room. 80mm rim and BFL should fit there nicely.

    I talked to them directly and they said that a 100mm rim with BFL would not clear the rear chainstays, although the front depends on your fork.

    I'm just going to stick to 100s with regular larrys

    After seeing a BFL on Hundies it is my honest opinion that most folks (including myself) will get by just fine with a BFL upfront...I'm just not convinced that the BFL is needed front AND rear... The BFL on a hundie looked to be less than a half inch wider and about a half inch taller...is all the additional rotational weight worth the extra girth? dunno. But I'm pretty sure me and my Fatback will do fine with one BFL up front.

    I like that idea, I think having the flotation up front would be good, I'd rather have it on both tires, but I guess one is better than none.

    Agreed that not everyone needs BFL, butbutbut:

    When the trail gets soft, which end sinks first--front or rear?!

    Rear sinks first.. more weight on it.

    At least on my setup.. I run a 50mm stem.

    Where I ride my issue isn't necessarily float...there are far more snogos (snowmobiles) than there are cars. Every day hundreds of people zip around between Bethel and the villages making grocery-runs, hunting trips, joy riding...whatever. We also get a lot of weather that contributes to crusty conditions. Therefore the trails can be pretty bomber all year...except during the typical mid-December and early February thaw. Honest truth is that a good part of the year a person could pretty easily get by with snowcats..though I do like my hundies...

    I feel that 100's are enough to help any of the previously available 3.7 / 4.0 tires float plenty well enough. My issues have been in the traction department (sometimes it seems traction is "...more luck than skill." right?)...Ergo, I run a Larry up front and a spider in the rear (Larry washes out way less than the endo and the spider climbs like a, well, spider. I'm thinking the positioning of the side knobs the BFL has will help when the front wheel gets stuck in a rut or against a berm and washes out when trying to steer out of it.

    I suspect the majority of folks on fatbikes aren't doing any Arctic (or sub-Arctic) bushwacking. Heck, I would guess that a pretty fair number are riding on groomed trails and that any floatation issues they do have could be easily (and cheaply) remedied by dropping a couple psi for the soft sections.

    I've got an early Ti Fatback and won't have any issues stuffing my BFL into anything, but do my well-marbled legs and under-utilized cardiovascular system need the added rotational weight and resistance of more rubber on the trail? dunno...I'll give BFL a shot and see.

    My VERY unscientific assessment of contact patch of a BFL v Endo (on 100's) is that the BFL may provide 15-25% (or more?) more contact than the Endo. Not a negligible ammount...but, how much more rolling resistance?

    I've also seen quite a few posts round here with similar opinions on runnin BFL front and rear...

    ...just sayin...

    Reading between the lines...had not concidered increased rolling resistance...

    Although there is more weight on the rear tire, wouldn't the front one sink first, given the tires are the same, since the front one would be more likely to deviate from a straight path and push through?

    Maybe I'm just confusing myself by overthinking...

    The rear always pushes through first for me. The front will float but my fatass busts the rear through the ice layer.

    The Big Fat Larry is reported to weigh about the same as the standard 3.8" Larry.

    Schmucker-70's, 80's, 100's?

    Concerning flotation...It is my oh so humble opinion that the rims are what makes the biggest difference...same terrain, same amount of squish, same tire...the wider rim wins every time...

    Wider rims also make a more stable, controllable and predictable ride.

    To be perfectly honest, aside from the new summer tire offerings, Now that I've fondled BFL, I'm really more interested in the new 100's from Speedway and Surly.

    -edit- oops, I guess the Speedways are 90's, though after peepin 'em at Speedway, they definitely seemed bigger...

    I'll soon be finding out if the BFL doesn't fit on the 907 with 80mm rims - I have a set on order.

    Just as well I haven't got round to sticking the Pug on eBay yet.

    It has given me an idea for the 907 though.

    Since running around on fat tyres, my 29er became redundant, so I stuck 2.35" Big Apples on it and it became my road bike, and I really enjoy the feeling of invulnerability to road surfaces that gives. Now there's a chance even that setup will become redundant because a set of Floyds on the 907, and "Hey Presto!" the ultimate fat road bike. The 907 should look ace with drop bars and road cranks etc

    I got to ride BFL's on 80's. No noticeable effect on rolling, and these were at about 5psi. Regular Larrys seemed to my "feel-o-meter" to be very similar.

    The thing is, the BFL's can be ridden at lower pressures without issue, where a regular Larry might get rim strikes and damage at the same pressure. That's our feelings here after thrashing them on a recent urban assault/single track ride.

    Sooo.......if that is true, the BFL's should produce more float without going to 100mm rims for most riders. This may allow them to be used on any current fat bike frame without too many drive train compromises.

    When the trail gets soft, which end sinks first--front or rear?!
    Obviously, the rear end, but why not run both ends with BFL's?

    Ok so I tried the BFL on the rear... No good with the GFS rim... I mean technically it 'fits' with about 2mm clearance on the chain stays and seat stays, but the little rubble molding nubs are in full contact with the frame, and any wobble in the rubber (forget snow or dirt) and there's healthy contact.
    Keep in mind this is the 2011 model with the 135mm Pugsley offset..
    The 2012 model may be different and I'm sure the 170mm model is different as evidenced by their Facebook photos... So... BFL up front, SL out back for me.
    I took pics, but of course I can never find the adapter to download them

    Edit: found the adapter

    Good job, confirms my initial thoughts on this subject...
    For my winter mud/snow duties I will be going for BFL on front, nate on rear for traction, both on 80mm rims

    Here it is mounted on a 70mm UMA II in the rear of a red-anodized (2010, I believe) frame. It fits, but the rubber molding hairs rub on the insides of the chainstays:

    Regular Larry on a 47mm trials rim on the front.

    I plan to stick to using it on the front for the moment. Fits the 100mm Pugsley fork just fine on a 70mm UMA II, though the tire needs to be deflated a bit to get the wheel on and off past the disc caliper.

    Can I get a sanity check on the width of a BFL on a 80mm GFS rim? The max width I tested of Larry vs Big Fat Larry didn't show all that much growth. What numbers are you guys getting?

    One more data point...BFL fits 100mm Pugsley fork on a 70mm rim with room to spare:

    <a href="https://www.flickr.com/photos/mababo/6159986223/" title="Larry vs. Big Fat Larry by Uncle Bicycle, on Flickr"><img src="https://farm7.static.flickr.com/6068/6159986223_0491030424_m.jpg" width="240" height="160" alt="Larry vs. Big Fat Larry"></a>

    Thanks for the photos. I like that orange/while color scheme too!

    Looks like I just might barely be able to fit a BFL on the rear on my 907 running Large Marges. And the front should be no problem.

    BFL works fine front and rear in a 2010 907 with a Pugsley fork on 70mm UMA II rims. Running 2x8 (full 8-speed cassette) with an Origin 8 Sub Compact 2x9 crankset.
