EB14: Open Cycle’s 15.12lb Race-Ready Hardtail Mountain Bike

Doesn’t count if it doesn’t have pedals… Or a real suspension fork… Or durable multi-use dropouts.

So this is this reason we are having problems with people sterilizing the trails. This thing will fly into a million shards the first rock or root it hits.

I did Leadville and Fools Gold 100 on my OPEN and have ridden Pisgah and dupont on it several times. It’s a great bike and I like the 2 person company. As for the rotor bolts, Several pro’s race only 3 bolts on the rotors. Everyone has a comment for this bike (often negative) when I am riding it (often passing them.) I’d love to purchase their new frame, the one shown here, but I have no reason to replace my current one which I love.

*snap*

This whole bike is a compromise in durability and refinement for the sake of lightweight. XTR shifts smoother and precisely than XX1. XTR brakes have better modulation and are stronger. Any conventional fork is better than that Lauf which lacks compression and rebound damping.

fork has got to go. shimano is better. three rotor bolts is not recommended for many reasons… i would have gone with the Extralite thru axle for the rear, must be lighter. and extralite hubs. at least the thing is clincher.
about the plastic housing end cap, i actually prefer them in most cases. note that the housing at that location doesnt have to move except when installing/removing the wheel. plastic doesnt corrode. i understand the preference for aluminum end caps when tight bends are required or the bend is dynamic, like at the shifter…

the stems face place gives me the most concern.. I dont see that lasting any offroad ride.. and a faceplate failure is sure to be catastrophic on your real face…

@PTymn Wolfe:

Cool build. I love the stuff those little nerds crank out.
@greg- get to work.

You can use many parts of the bike as a toothpick after your post ride meal!!!!!

Is it only me who misses Carbon-Ti carbon-steel rotors? Would save a lot. But cool build, nice with people pushing boundries.

Weird build. 3 rotor bolts, but they look like steel. Why not go 6 alu, or 3 ti/3 alu. Heavy rotors too, and ESI grips aren’t light. Then they’ve stuck a daft fork on. Thunder Burts and a tuned SID would be more impressive and useable in my eyes.

Not liking plastic ferrules though…? That’s what Shimano ones are, I’d not use anything else.

The fork is a joke, and who rides without pedals? Why not quote the weight without saddle, or grips or tires?

A lot of people are going to lose their s**t if this comments section is anything to go by when the Open full susser gets released.

I like it. You know, innovation for the masses comes often from pushing the limits in one direction or the other. Carbon frames at all used to be considered plastic toys only the elite could afford, now they barely steal a glance from most people.

I do like that the focus is still “raceable”, though just how much is left to the reader to decide. You could make it a lot lighter with a rigid fork and a single speed drive train, for sure.

I wish any of my bikes weighed that much. This thing just SCREAMS “Fire road racing!”

I really love this bike! The fork is boss, the rotor bolts are sweet as well as the plastic cable end caps, the best bit is its probably lighter than all the bikes of you other knobs passing judgement on a bike you’ve never ridden. You are all probably annoyed the post didn’t mention a reference to enduro! Lauf leaf forks rock and they have great styling too.

Yeah! “Fire road racing!”

I googled ‘math’ and figured out how to combine the listed weight of the bike and my preferred pedals.
try it, it’s fun!

..horses for courses, and while this would in no way be suitable for my riding terrain there are places where this bike would be entirely suitable. Durable? maybe, maybe not but ffs all the negativity.. Lighten up Francis.

Building a mountain bike lighter than the 7 kg UCI road racing weight limit is an impressive exercise in weight weeniness. I still question the value of something built purely for lightness because ultimately you must a finish a race in order to win it and to me ultralight parts are asking for a mechanical. This bike goes well beyond what the top level pros do to their bikes so I question the real world performance of this bike on anything other than the smoothest, most buffed out racing trails.
Oh and @delquattro, the problem with electric bikes on the trail is not with technology, it is with the very principle of using a motor of any kind on trails explicitly labeled for non-motorized recreation. The enthusiastic response to Di2 and electronic suspension controls shows that the MTB community is perfectly OK with motors and electronics to move stuff on the bike but have serious philosophical issues with using a motor to move the bike itself.

I have a carbon hard tail with a Lauf fork. Done about 14 races on it,won a few and came second too. It totally depends on what the course is like. The fork has definitely limits. Nobody would show up at downhill race with XC race bike. Mountain biking is so diverse these days. Haters on the net…can’t stand them.

Sorry, I just realized it is a wide narrow chainring. I take back my chainring comment.

…just get a CX bike!

😉

I am sure some people (skinny) people get away with bike like this… but I am also sure it is not crash worthy. Since I gave up MTB riding and racing 20 years ago I don’t know much about MTB tech but I would love to ride a 15lb MTB (as long as I did not have to pay for it).

no need to skip rotor bolts, just get a set of Proti FFR Titanium bolts, is the lightest and strongest in the market. They have a Blue color that would go perfectly with this bike! They also have other kits for stem, brake calipers, bottle cages, and individual sizes as you wish.
