Park riding, freestyle, grinding rails or dropping gates, Redline means BMX. In a five-speed transmission, there are five different gear ratios that relate to the input shaft in order to yield a different rpm value for the output shaft.ĭespite the redline guideline, there is still only a narrow rpm range in which your engine works its best in terms of torque and horsepower. The transmission's input shaft has to spin at the same rpm as the engine. The clutch is what connects the engine to the transmission. The shift lever controls rods that control forks that engage the gears. To shift gears, you move the gear shift and hold down the clutch. Black Anodized Aluminum and Sealed Bearings.

Since you would probably prefer that your engine not explode, you have to keep an eye on the redline, especially in a manual-transmission car. Beyond the redline, the engine will explode. Redline Micro Mini 18' / R6 Aluminum / Integrated Headtube and Euro BB / 3-D Forged Dropouts. Manufacturers tried to offer 'double row' bearing systems (i.e.All engines have a redline, which is the maximum rpm value they can accommodate.

When you try and manufacture a bottom bracket to fit inside the Euro shell, and support the 19mm-22mm axle, you simply don't have enough space left for cartridge bearings of sufficient depth to withstand the high stresses, strains and impact loads of aggressive riding Ideally you want the largest possible diameter crank axle on a crankset for strength and rigidity - ideally around 19-22mm The problem with the Euro shell is the limited diameter, it was never designed for aggressive riding on mountain bikes, its a leftover from the world of road bikes! I cant see how having internal bearings is any weaker than having external bearings? To summarize: just about any crankset will work on your frame, provided you don't cock the numbers up too badly (by getting, say, an 83x122.5mm Square-taper BB for a set of Shimano Dura-Ace cranks - though if you do manage to do that, I have a cookie reserved for that level of stupidity) I'm assuming you're planning on single speeding your Traffic? Just grab a 113mm BB and be done with it. However, anything that uses an internal-bearing BB (any ISIS, square-taper, Octa-Link, or BMX style cranksets) will require you to pay attention to the spindle length. If you go with a crankset that uses an external bearing BB (like a shimano, or Race Face), then you don't have to worry about it, as it's sort of one-size-fits-all. If I'm not mistaken, your NS uses a 68mm shell, which means you'll be able to use either a 68mm specific BB, or a 73mm BB (and just use five mm worth of spacers, as instructed by the BB's manual).Īs far as spindle length (that pesky second number) goes, it will depend upon your frame, rear hub, and crankset. There are no instructions included and I can't seem to find any info.

The 19 and 22mm measurements you keep referring to are diameters, not lengths (a 22mm wide bottom bracket would be absolutely tiny! about the width of one of your crank arms!).Įuro BB's have their own fun standard as far as sizing goes, and most will follow the typical 68/73mm shell size (read: they'll fit either 68 or 73mm wide bottom bracket shells), and be between 108mm and 133mm in spindle width (113mm is the most common size used in the industry).
