It was only a matter of time, of course, and now it’s here. After rebooting their carbon fiber JET9 and RIP9 lineup to make them Boost and 27.5+ compatible, the shorter travel JET9 is now also available with an alloy frame. Geometry and design carries over, it’s just less expensive…

Up front, you get a 130mm travel Rockshox Yari RC fork to create a 67.5º head angle.

Their proven CVA suspension keeps the rear wheel tracking without bobbing under pedaling, making Niner’s bikes capable climbers and descenders. Helping keep you sane is a standard threaded 73mm bottom bracket shell. 

Like the carbon RDO models, this latest iteration gets shorter 434mm chainstays and a slightly steeper seat angle and longer reach, keeping your weight centered in the bike while improving overall handling. Boost spacing out back helped that happen while also letting them increase travel to 120mm and opening up tire clearance to 29×2.4 or 27.5×3.0. This puts the JET now squarely in the trail category, leaving full suss XC duties to the RKT9.

It’ll be sold as a complete bike with 29er wheels and a SRAM NX1 build for $2,600, shipping to dealers this month (October). That includes a Rockshox Monarch RL shock, alloy Niner cockpit (bar, stem, post), and SRAM Level brakes. Other standard features include internal and external dropper seatpost routing, ISCG05 mounts, 30.9 seatpost,

The longer travel RIP9 got its alloy version at the end of August, so now the line is complete.

Well done Niner. I love it that you guys are still building aluminum bikes for the working class people like me. In a world of $5,000+++ carbon fiber superbikes getting all the press lately, it is nice to see a very well put together aluminum bike for a great price that takes both 29″ and 27.5+ inch wheelsets. Would be nice to have a dropper, but that is a pretty personal choice and I guess would drive price up.

Sevenpointfiveplusser just doesn’t have the same ring to it.

Tire clearance looks like a serious issue from those pictures

I dont see that at all. There is a pic of the rear triangle brace from an angle and it looks like its off to the side a bit. Maybe its deceiving if you look at it from the side?

If it’s anything like the new alloy rip, there’s LOTS of room. That vertical brace in the third picture is between the left stays, so it isn’t near the tire at all, although the picture makes it look close.

Is anybody really riding full suspension 275+ bikes? If so, are they super awesome? With the number of new bikes like that it makes me wonder.

“Super awesome” Eh, depends on your taste. I got to spend quite a few miles aboard a Salsa Pony Rustler this summer and found myself *wanting* to like it, but… meh. I have friends on the US East Coast and they all love the 27.5+. Here in the PNW, I really preferred the Salsa Horsethief–same exact frame, just 29r wheeled version.
Pros: Tons of traction up hill. Steamrolls EVERYTHING. Fun enough.
Cons: Steamrolls EVERYTHING. High rotational mass, not a nimble or fast climber, not nimble at all, really.

My take was that it was fun, and if you enjoy the novelty of regular fat bikes you might also enjoy the 275+ full squishers. For me, a 29r running 2.4 tires rolls better, climbs better, and still requires some degree of technical handling to negotiate the trail, versus just plowing over everything. The longer travel regular 27.5 bikes ride great too, and I enjoy those where applicable. I see the merit in a 275+ hardtail, and see where it could be fun, but the 275+ dual suspension just doesn’t do much for me.

I thought the same thing as you until I found the right tires. I think the maxxis 2.8 tires roll nearly identical to a good 29er and the downhill traction is insane. I don’t really notice any negative uphill performance and it’s better traction there as well. However, I still primarily run 29 because I think it’s a better all around setup.

I agree that the 2.8s seem to be a bit better than 3.0s, noticeably so. It’s fun to be able to lean the bike over in corners–you’re pretty much dragging handlebars in a berm. Still, and like you mentioned, I like my 29r better because it’s more well rounded. I *did* notice a huge difference climbing, but that may just be riding style. There’s a fun, novelty to 27.5+, but I’d never have it as my only rig. Even for a wet season hardtail, I’m still probably picking up a Kona Honzo AL and running some Maxxis Shortys for the muddy stuff.

East coast, it is pretty awesome to take the bite out of the rocks. That being said, i haven’t had so many flats in a long time. The good news is a slosh of the tire, sealant finding the issue, and a quick hand pump back up to pressure i haven’t been left stranded anywhere. I also hold all my PR’s now with a plus bike over various 29’ers and 27.5 with no marked increase in fitness.

I love my 27.5+ Hightower (I call it “29 minus”). Rips up the descents. No need to pick a line.
