2007 Yeti 575

Finally got some good pics of my silver bullet - 2007 Yeti 575 with aluminum rear triangle. Set up with the American Classic rims - 2.3 Neo on front and 2.1 Neo on back. Fox Talus 110-120-140 forks with lots of room with a 2.3 Neo. Ground clearance to BB is now 13-in. and no more bone jarring pedal strikes ! The rear wheel setup was defintely a tight fit with the 2.1 Neo - had to have my rim trued to take out the slight wobble. Then after a few rides the wobble reappeared - so filed off the knobs on the chain side. Pic 2 below shows the width of a 6-ft. ruler between the tire and aluminum brace. Pic 3 below shows a little daylight between the filed knob and chainstay.

I flipped over the stem for a negative rise - to drop the bars and keep the front wheel down. Also dropped to a front big ring of 42t -- huge difference in keeping the momentum and accelerates better ! And switched to a 24t granny gear to reduce the chain slap when shifting from the middle ring and keep that low goat climbing ability. Love this beast on the nasty, rocky trails and the 650b rolls so much better. The 650b conversion has turned this bike into a different animal !

Nice. I am surprised your 2.1 gave you a fit issue. I suspect minor differences in the dish of the wheel build could cause this due to the close clearance on these Yeti's. I was able to run a 2.3 Pacenti on mine, with a bit of wheel truing and knob shaving required because I would get wheel flex into a rub without. A 2.1 never hit. Nice fork setup too - those Talus forks are super nice.

was surprised also that the 2.1 was so close. For fall, winter, and spring I'm planning to put on a 2.3 on the back and shave the knobs. The 650b is that good that I will NEVER go back to the 26-in rims. Hope to try out the Stans 650b flows but am concerned about the rim width and how it will flatten out the tire causing major rubbing.

really love the Talus forks and being able to open it up to 140 when the trail gets rough and nasty. Had to have the forks rebuilt this May and Fox rebuilt it with all new valves and seals for less than $250. I like to run the forks a little stiff to keep from flatting (seems to bounce off rocks rather than catch the sharp ones) and now it bombs the rocky sections.

Yes - the Flow rims look right (from the website). Thanks for the correction.

Hey jnordby ! Time to resurrect the thread. I'm looking to see if Stans Flows will fit with the tight clearance. My american classic 650b wheels are tight now with a 2.1 neo-moto on back. And want to upgrade to the new Flows if I can get my hands on them. Are these the ones you have that work for your rear triangle ?

If not, I will have to wait until the 650b ArchEx hits the street. My concern is with the wider rim bulging out the tire to make a tight fit now even worse. My earlier pics show how tight it is. Thanks.

Nope, I was using stans 355's - I did have a neo 2.3 on there, but had to shave knobs to do it. It would still flex into the frame under load though - a 2.1 was the right long term solution for that conversion - not ideal for that bike, 575's should have 2.3's and 2.4's on them!

I'm thinking if you spread that casing out too much you will flex that wheel into the swingarm.

Guess I'll have to go with the ArchEx when they become available. And may go the route of putting a 2.3 neo-moto on the back with the assumption I have to shave it some on the drivechain side. That will work for me ! Thanks.

Hello you guys, I've discovered your thread because I've recently purchased an XL 2007 Yeti 575 to replace my 2009 model (until the crack in the downtube can be repaired, if ever) (It makes me want to cry) I got to thinking about converting the 2007 model over to 27.5 " wheels, Googled '2007 Yeti 575 650b 27.5 conversion' and eventually found my way to the men with the answers - you. I was looking at some new Stans Flow Exs that were take-offs from some guy's Rocky Mountain Altitude 770. I'm a big dude, 6'3" 240 pounds, and I need the extra support of strong wheels, but there's the consideration of width, isn't there? What are your thoughts so far? In reality, I use my mountain bikes as city commuters, so I don't need knobby wheels, however, I like the extra width, but I should understand all the dynamics involved before I end up wasting any of my money. The biggest problem I face is that the 27.5 movement hasn't affected Baku, Azerbaijan, one bit. It doesn't even exist here. So, I can't run over to my Local Bike Shop to get the help I need to 'check it out' before making the investment. If you think I will be able to pull this thing off, please advise. Thanks.
