2019 UCI MTB Rulebook Fixes DH Finals Start Order, Allows For Mismatched Wheel Sizes & More
@TheUnknownMTBR: I'm not talking about physical clearance. I'm talking about preserving geometry. Physical clearance is unaffected by changing your fork travel anyways - a 160mm fork at full compression is exactly the same as a 140mm fork at full compression (dual-crown DH forks aside). If your frame doesn't have the clearance for a 29" wheel, the only solution is adding an extended lower headset cup (a la Pivot with the Switchblade)

@TheUnknownMTBR: Not significantly. Using the fork lengths for the 36 and assuming that the wheels (with tires) measure true to size, you get an difference of 37mm on the front end. With a 65 degree head angle, that means the bars come up 33mm. Going by the generally accepted rule of not changing stock travel (i.e. fork length) by more than 20mm in either direction, that means you'd want to go for at least 20mm less travel when switching from a 27.5 front wheel to a 29er front wheel.

@tremeer023: And a 29er wheel is, in theory, about 3/4" taller at the axle than a 27.5" wheel. Add the two together and you get a height increase of about an inch and a half (~40mm). Definitely a good idea to use less travel in that situation, especially if your bike is up-forked to begin with.

@conoat: You also have to account for the longer axle-to-crown of the 29er fork. A 160mm Fox 36 has an A2C of 549mm in 27.5 and 567mm in 29, so between that and the increase wheel diameter, you're looking at the front end coming up about an inch and half to two inches. It makes sense to drop around 20-30mm in fork travel under those circumstances.

@Kickmehard: You would use a shorter travel fork. For example, if I was to throw a 29er front wheel on my Mach 5.5 (160 front, 140 rear 27.5), I'd probably run a 140mm fork. Works best on bikes that are over-forked so that the travel isn't too mis-matched.

The Mechanic's Special - Interbike 2018
@loganskis: Sure, but the point is that you could buy ten for what the EVT version costs. You're not losing anything in terms of function - they're both very accurate and both have a bleed valve - so in order to justify spending 10x more on the EVT, you'd have to be sure that it will last 10x as long. Even if you're only getting a year or two out of an AccuGauge (and I suspect that most don't die that quickly), that's still 10-20 years that the EVT gauge has to last you.

Love me some EVT stuff, but that pressure gauge is probably the least-justifiable tool they make. These are almost as nice (not CNC'd, but still all-metal) for about 1/10 the price: https://www.ghmeiser.com/bicycle-gauges.htm
