40-Series Integrated Alloy Tall Top IS41 IS41/30 Headset
Cane Creek's 40-Series Integrated IS41 IS41/30 Headset certainly gets the job done, but you'll be able to appreciate it for more than just how well it works. It offers up a clean look with smooth performance, durability, and big-time value. It's the simplest of all of Cane Creek's 40-Series Headsets since the bearings drop straight into the head tube. But that's the beauty of integrated headsets. Aside from pressing on the crown race, all you'll need to install the 40-Series Headset is a hex wrench to preload the bearings and torque your stem to spec.
This 40-Series Headset spins on Cane Creek's black oxide bearings. The races and balls start out as 52100 steel and are then given an acid bath to make them more corrosion resistant, while still being porous enough to retain grease. They are angular contact bearings (ACB), which resist both axial and radial loads equally well. The cartridges are sealed with what Cane Creek likes to call a Split Lip Seal, which has two contact seals per side to better keep out contaminants and hold in grease. To augment the seals on the cartridge bearings, Cane Creek adds face seals to the crown race and top assembly. So what if the bearings aren't stainless -- grease kept in and muddy goop kept out keeps 'em running like new for a long time.
In the event that you might wreck the bearings through normal use or abuse, you should know that all the internal parts in this 40-Series Headset are compatible with their top-of-the-line 110-Series Headset. So you could always upgrade to the 110 headset's stainless steel bearings. The Clip-Seal in the upper assembly holds all the parts together, including the compression ring. This makes assembly a cinch, since there are no loose parts to misplace or install backwards.
The Cane Creek 40-Series Integrated Headset has a top bearing cover that's CNC machined from 6061 T6 aluminum, and it's polished and anodized Black. Cane Creek adds laser etched graphics to the top cover, including their Skink logo. This is an integrated headset that will mate a fork with a straight 1-1/8" steerer tube to a 1-1/8" straight head tube having a 41.1mm i.d. The top bearing cover is compatible with Cane Creek Interlok spacers. The stack height for the top bearing cover assembly is 15mm and the bottom is a mere 1mm.
