It's a SpyLamp 2 from Integrated Trackers. Mind you, no serious weight weenie would consider preventing the loss of their bike more important than saving a few grams :D

Wow that is light, nice effort, good effort starting with 4kg of frame and fork.

Thanks Ragan, I was thinking of using it only when leaving it home alone :)
my 10.1 kg 27.5 Flux needs no extra weight while riding :lol:
Nice build :beerchug:

With 26ers going obsolete in a hurry, there are some good deals to be had as dealers get rid of their old stock. This frame and fork were sold as a bundle for at or below the dealer's original cost, so it was take-it-or-leave-it on more fork that I really need. The original plan was to do a 650b conversion, but buying the frame bundled with a 26" fork put that on hold, and recently I was able to get the EC90XC wheels for well below the original dealer's cost. Likewise, it's a 1x9 because I had some 9 speed parts lying around, and while I planned to upgrade to 1x10 or 1x11, I found that I could find some nice deals on 9 speed leftover parts like the grip shift.

I will just have to be "that guy" on the group ride swanning about on a museum piece. Here it is with an old pair of Industry 9 wheels, relics of a bygone age:

That much travel, those tires, those rotors, no dropper...

Lovely looking bike but what's it for? :noidea:

Perfectly reasonable question, I doubt anybody would sit down with a blank sheet of paper and "design" my bike.

Those wheels and tires are for ordinary fitness riding, mostly road and gravel trails at this time of year. I don't own a road, CX, 29er, or fat bike for winter riding. In season, I've been riding the trails with Rocket Rons, tubeless, on I9s with Stan's Flow rims. I expect that come next spring, the RoRos will come out again.

Now about the travel: I'm not into enduro or DH, But I do like to ride stunts. It's certainly a lot more forgiving on my back to nose-pivot or rear hop off a big log onto 140mm of rear travel than onto my old hard tail.

This bike is an hotch-pot of left-over bits and pieces. You can honestly ask "what's it for?" about everything. For example, who rides nine speeds? What's that for, when you can ride SS or 11 speed? Those wheels, what are they for? Any place where you want sub-1300g wheels, don't you also want 29" wheels? That frame, what's it for? If you want 140mm of rear travel, don't you also want a MOJO-HD that can handle rougher use and has a slacker head angle?

What this bike is for is maximizing my fun while staying well within a certain budget. So... It has the frame that my local Ibis dealer was trying to get rid of at a discount, it has the fork that came with the frame, it's a 26er, it has the wheels that were on clearance, it has 310s for road riding instead of 285s, &c. &c.

If it suites what you want, it's the right bike!

It's light enough to ride as an XC bike and it's got a bit mire travel to take you over the rougher stuff without having to worry about it.

I'm still on 9 speed as well, although only my road commuter has a twist shift, the MTB is on Shimano 'flappy paddles' as is a friend form work I ride with.

Anyway you have a beard, so are required by cycling law to do things differently!

I run a 160mm Scott Genius 27.5 with no perceivable loss of efficiency. Long travel is awesome for most situations, even climbing. For that I'm willing to give up a little bit of top end to have a bike that is way more fun to ride. For those who think 5-6" bikes are some sort of freeride shredding machine I'm sorry to say that mentality is just wrong. Oh and I don't have a dropper post either. I swapped mine out because I never used it and I hate having so much junk on the bars. You can put dropper posts in the hype bin with wide bars and 1x drivetrains. They may be great for some but not my cup of tea for the way I ride.

Did you find much benefit of moving up to 160mm? I was thinking of putting a Fox 36 on the front of my Genius but I was going to run it at 150mm to keep the geometry the same.

And for people that like to ride uphill and downhill droppers are the best thing to come into MTB since suspension that works.

My bike came stock with a 160mm 34 TALAS so that's what I use. Though the rear end of the Genius is a little dead so probably a 150mm fork would match it better.
Since I only use it for XC, a 36 Fox would be a move in the wrong direction for myself.
I respectfully disagree with your opinion of dropper posts ;-)

I actually own a dropper post, and it has been on that bike, along with Titanium-axled flat pedals and I9 all-mountain wheels. IMO, we're living in a weird time where manufacturers haven't figured out how to make them at a reasonable weight yet. The Lev Carbon, for example, is still a whopping 400g and only drops 65mm.

Once the weight of a dropper post comes within striking distance of an alloy post's weight, I think we'll see a "tipping point," and then most trail bikes will ship with them right from the factory, the way enduro bikes ship with dropper posts today.

I don't need one for keeping fit over the winter, so I have my old P6 on. But when the wheels get wider, the post needs to drop :-)

How strange. the factory spec for all the 2013 Genius's was a 120/150 TALAS. And...

Yeah, but you also disagree with your own opinion. How can they be only hype but great for other riders?? :wink:

Mine is a 3-Rox team bike so came with its own spec.
To me the hype manifests itself in the fact that the dropper Jehovah's can't accept the fact that some riders don't like them.
