Santa Cruz Flip chip & fork

I was reading up on the flip chip and it says you "must" change to a 140 fork when switching to 29er wheels. Can anyone explain why this is? Is it strictly because of the geo or will the bike explode and burst into flames? I'm allergic to fire.

My bike is a Hightower and currently on 27.5 wheels and 150 fork.

It will probably chopper the fork a bit but the change in geo is so small, you can probably deal with it. However if it is a fox fork, the air shafts are pretty cheap and easy to install. I did my Factory 34 in like a half hour.

Nothing will happen. It just doesn't optimize the geo for wagon wheels. The wheelbase will be like 5mm shorter and if you're running 180mm cranks you might hit your foot.

I keep my Stumpy in the low BB setting with both wheel sizes.

If you are looking to switch back and forth you'll want a second fork. That being said all the bikes which use this as a selling point, but how many do it after settling on a tire size? The manufacturers are probably actually saving money from needing to retool for two frames

Will the 27.5 fox fork fit 2.6 29r tires?

If you're serious about swapping wheels you buy the 29er version and then get a second set of 27.5 wheels. The smaller wheels will fit anywhere a 29er will but it's harder the other way around. 29er wheels are significantly larger than most will make them out to be.
