Help me Understand 29+ Forks

I have read several posts on here about new forks for 29+, but I struggle to understand. I have a 2017 Stache 7 with a Magnum Comp fork that I'd like to replace with a higher-end fork. I find that the small bump compliance on the Manitou isn't very good, and I often feel like I complete my rides on a rigid. I have been looking at the Pike, which I understand has several options for wheel size: standard (?), boost (27.5+ and 29), and 29+. When looking for options to purchase the 29+ version, I struggle to find anything available. There are, however, plenty of boost options available for good deals. But then I read about folks using standard Fox forks on their 29+ rigs and having plenty of room to spare (depending on the tire). Ultimately, my question is this: should I spend the time and money looking for a 29+ specific fork, or would a boost option that is NOT 29+ specific also work? If so, how do I get a list of options?

For Rock Shox you need a 29+ version. Most if not all the 27.5+/29 versions will not fit a 3" tire. Fox 34 will fit most tire and rim combos. I believe the Minion and similar aggressive tires can cause fit issues. Guaranteed fit = 29+ fork. If you research you can figure out which Fox 34 models work and with which tires.

Thanks. I guess my next question is where to purchase 29+ forks? I seem to be having a hard time finding them. I’ve checked eBay, Pink Bike, classifieds, local shops, and manufacturers. Perhaps I am missing something.

RockShox Lyric is the way to go. I bought mine from Mikesee at LaceMine29.com -- he steered me into the right fork for my 29x3" wheels (which I also purchased from him and are gigantic).

On another bike I have a boost Pike 29" fork -- it's not nearly big enough to handle true 29+ wheels & tires.

Universal Cycles has a few called out on the site as being 29+ fork.
Honestly it's been a while since I have looked for a 29+ fork, and shockingly they are hard to find. If you dig into RockShox site it does list wheel size. The Pike RCT3 has 29+ as a wheel size.

I'm riding a 27.5+/29" Lyrik on my own bike, with 29 x 3" tires. It's fantastic.

There is also a 29+ Pike available that has yet more clearance than the fork above.

But honestly, I'd spend the time on your current fork, figuring out what is keeping it from giving up the small bump sensitivity you seek. That's a good quality and reliable fork. Perhaps it came with no bath oil, or maybe an internal o-ring is cocked up and making things sticky.

Not super difficult to drop the lowers, clean, lube, and reassemble. Inspect the air shaft while you're in there. Dump the pressure and verify that it slides easily, without friction. Lube it. Slide the damper shaft up and back and see how it feels, too.

I like buying new things to solve problems. But only after determining that I can't fix the problem with a little time and elbow grease first.

I 3rd having the Magnum looked over first. I've only ridden the Pro versions of the Magnum, but have been very impressed with them.

RockShox is getting a little in the grey area now. Seems with their newer forks, they have dropped the 29+ designation. You have to look at the forks max tire clearance spec. All of the RS 29+ forks state 81mm max tire width, well now the normal 29 Pike Ultimate & Select list 81mm max tire clearance as well. Same goes for all the 2019 and newer 35mm chassis RS forks (Gold, Revelation,Pike, Lyrik).

^This^.

Why? No earthly idea.

The Pike on my Krampus is fantastic.

That said, agreed, the name on the fork isn't the guarantee of anything, have it looked at, particularly if it's been ridden a year or three.

Perhaps I will look into the fork a bit. As stated, it's the comp version, which I have read is considerably less smooth than the Pro.
Can it be? Any fork *can* be less smooth than another.

As a rule I haven't found the Comp to feel much different than the Pro. Slightly less easy to adjust to nail preferences, but that's about it.

From my experience the Magnum Comp was not a good fork. It felt dead to me. Zero small bump compliance. That coupled with wanting to lose some front end weight brought me to a Fox 34. If you can get the come squared away that's great, but don't spend too much money or time on it.

Your Magnum Comp is a good fork. I have a '17 Stache 5 and was very impressed with the entry level Manitou fork on it. I found a great deal on a take off Pike from a Stache 9.7 and jumped on it.

I'm running a Minion DHF 3.0, about as big a 29+ tire as you can get, in a Fox 36 29er. It is boost. Just barely fits. Also fits in a 34 27.5+, again just barely. Other 3.0s fit more easily (plenty of space at side of tire, just height is very close)
