6″ bottom bracket spindle now in stock

We now have 6-inch (152mm+) long bottom bracket spindles in stock. Measuring at 3/4″ (19.05mm) in diameter with the tested-and-proven 48-spline design, these shafts are basically compatible with any and all crank arms that follow the same standard, including the original and still popular Profile Racing cranks.

6" spindle kit

Coming about 1/2″ longer than regular BMX ones, this spindle is a perfect match for street/dirt MTBs, namely our very own Tanatos. As long as there is optimal engineering, 26ers always come with a wider chain line than BMX, requiring longer BB spindles to accommodate BMX-style 3-piece cranksets. If you look at the several choices of MTB-specific chromoly cranks out there, the only fundamental difference from the 20″ counterpart is the spindle length.

Now, the problem with MTB-specific 3-piece cranksets is availability, owing to smaller market size. That’s why we are making at least the spindle available, so that you can make use of those good ol’ 3/4″ BMX cranks lying around in any household.

Historically, NSP has not really been a huge fan of the 48-spline. There have been too many name brand 48′s that slip in and out easily when serviced, costing you the rotational looseness when ridden. This spindle, however, came with a warning from the factory: “installation can be a bit ch as you have to press it in.” That tight tolerance setting, so far, has felt great during installation and riding.

Spinner “Cargo 34″ MTB suspension fork – NSP special spec

We are now offering suspension forks for 26″ MTB.

As component standards vary as widely as never before, it is sometimes ridiculously hard, if not impossible, to find replacement parts for good ol’ standard mountain bikes. So here we are, adding a quite ordinary MTB fork to our lineup for you.

Just skip the following section to photos if you’re not into tech details.

There is a good reason forks are subject to the rise and fall of various standards; all of the interfaces between forks and surrounding parts are fierce battlegrounds between standards.

Let’s start from the top. The steerer tube, or steering column, is where the fork is attached to the frame. Long ago it was 1″ (25.4mm) in diameter, but since about a quarter century or so ago it has settled at 1-1/8″ (28.575mm), first on MTB and then most all bikes, now including road racers and BMX. At the tip, that is. The bottom part of this tube, though, is now growing in size to secure rigidity. That’s not a bad idea at all per se, but there still are plenty of frames out there that have straight 1-1/8″ head tubes, including our very own Tanatos, that are not falling behind in terms of performance. On the other hand, aftermarket forks are almost all tapered now. This is the primary reason we ordered these fork to such specifications as explained here.

Next issue is tire size. As mainstream tire sizes changed from 26″ to 29″ and then to 27.5″, forks have been redesigned, since there is only so much tire size difference a fork can cover. We are maintaining our love of the 26″, so this is the second reason behind us offering this fork.

The next standards war theater is the brake mount. Typical forks used to have rim brake (cantilever brake) mounts, then IS disc brake mounts, and now post mounts. Post mounts offer easy adjustment, fair performance, and compatibility with much older brakes as well. So this was an easy choice, we went with the flow.

Now to the bottom end of the fork, the interface with the front hub. Major options that have existed include 9mm quick-release axle, 20x110mm thru axle, 15x100mm thru axle, and 15x110mm thru axle. Out of these, quick release is simply a fail. You shouldn’t just employ what worked fine on rim-braked rigid forks, risking rigidity, strength, and even your life as the braking counterforce will always try to pull your axle off the dropout. 20×110 was an attempt to overcome these issues, and has been the standard of choice at least in the gravity sector for 2+ decades. Then some moron seems to have thought, “hey, we can then make it lighter and cooler if we reduce the diameter, right?” and came up with the pointless 15x100mm. The “Boost” 15×110 is not much different AFAICS, lacking proper engineering. If you wanted a lighter setup for lighter-duty use, you could have just increased the hollowness of axle (with thinner tube wall). “Smaller diameter axles should allow for use of smaller bearings = weight saving, yay!” says armchair worriers. In reality, lots of hub manufacturers employ a common design for front hubs, just with different end caps to accommodate different shaft diameters. So, we chose 20x110mm axle standard in consideration of rigidity, strength, and for avoidance of short-lived buzz standards.

Black or white. Steerer is 265mm in length uncut, though may not matter much.

Air spring in left leg. Right leg has a cartridge damper, with lockout dial at the top and rebound adjuster at the bottom. You could make the lockout to work somewhat as compression damping adjustment, but that’s not usually necessary. Personally I keep it open so that the suspension actually works, wherever I ride including streets. The air spring keeps it from bottoming out anyway so that helps make matters simple.

Trusted 20mm axle. Post mounts are ready for 160mm rotors.

Sample setup, shortened to about 110mm here.

The travel is 150mm shipped, with our original reducer kit included. Combinations of special washers and sleeves allow you to adjust the travel in about 5 steps down to 80mm. We’ll prepare a separate article about installation (pretty easy).

There is one important point to note. You can put this fork on our Tanatos frame, but it’s originally an all-mountain freeride fork that boasts high rigidity, and not intended by manufacturer for extreme freeride or dirt jumping. Please be reminded that it doesn’t share the same end of the spectrum in terms of application, strength, and other priorities in design with Libido Bike Co. products.

We have tested three of these forks since Spring 2018. Two out of those have survived occasional use in street, dirt, pump track, mini downhill and North Shore-like mini trail, in temperatures varying between 30 deg C and -10 deg C, just fine. However, the other one ended up rocking the chopper style with bent crown, after repeatedly casing 4-meter doubles and so forth. We know no forks are indestructible, but we know it sucks when stuff break, hence the rather affordable price setting.

LiBCo. Clicker MTB cassette hub

Here is a rear hub that goes along well with the new Tanatos frame. Since the frame features closed dropouts, typical and common hubs with fixing nuts cannot be used (you could cut open the dropouts to make it work like that, but that’s where the Mottainai spirit kicks in and we do not recommend it). This hub, however, features fixing bolts on both ends, enabling you to run it on Tanatos as well as use it on other frames with horizontal dropouts and enjoy easier wheel removal. That is, once you remove the bolts, the wheel just drops without any need to derail or cut the chain.

Update: In addition to the 11T 1-piece cog, we now offer the 2-piece driver version to accommodate 12+ teeth sprockets. For street riding (i.e. if to be put on our Tanatos frames) we would recommend 11T, but the larger cog version brings a lot more options for those who ride single speeds in the mountains and so forth.

Update 2: For 2-piece cogs, you can now choose any number of teeth from 11 to 16.

Currently we do not offer any complete wheel kit but just the hub.


  • Single-speed hub for MTB

LiBCo. wide shell Spanish BB

We are now offering bottom brackets that fit the new Tanatos frame. The frame employed a special variation of Spanish bottom bracket with wider spacing in order for the pursuit of ideal geometry, strength, lightweight, and reliability. The bearings are identical to Spanish ones used for some of the BMX bikes, but the intermediate spacer measures different at 71mm in length (which actually is identical to the spacer used for outboard Euro bottom brackets from some other parts makers). You don’t normally need this kit because the Tanatos frame set always comes with this, but you can make use of it if the original BB kit becomes defunct, you need just bearings for another frame, etc. This kit comes with a 71mm sleeve as well as spacers 3mm and 1.5mm in thickness, 4 pieces each.


  • Spanish type bottom bracket
  • Works with 19.05mm (3/4″) shaft
  • Weight: 113g
  • Color: Green/Black
  • Materials: Bearing steel (bearing), alloy (spacers)


  • 37mm bearing OD, 19.05mm (3/4″) bearing ID
  • 71mm sleeve length (70mm as in spec, with positive tolerance)
