Ringleé makes four types of hubs, in up to seven colors, with three hole drillings, and possibly two variations on the rear spindle length. Our computer system is capable of selling these hubs in pairs according to your specifications, so we are going to discuss each of the hubs individually. At the end of this Ringlé section we will provide you with pair prices, and options to make pair "kits" from among these four hub types and their options.
The Bubba front is their standard front hub. It's machined from 7075-T6 aluminum rod. The hub shell is turned on a lathe station, then bored from each side to make a seat for a precision sealed cartridge bearing. The second boring drills through the hub to make it hollow, reducing its weight. The bearings are Swiss made WIB #629. The axle is made of aluminum with a 9mm outer diameter, and a 5.25mm inner diameter. The axle has a 100mm over lock nut length. At each end of the axle is a 10.5mm long collar to space the hub properly in the fork blades. The collar is held in place on the axle, (when not installed on the fork), by an inner O-ring, recessed inside the collar. The collar is conically shaped with an 18.9mm contact face that is knurled to grip the fork blade. The collar isn't large enough to cover the bearing, which leaves the bearings own seals exposed and the only line of defense from outside contamination. The Bubba front hub has a 47mm hub flange diameter, with flanges spaced 68mm apart. The Bubba front spoke holes have a 40mm center circle diameter. The Ringleé Bubba front is available in either a 28 or 32 spoke hole drilling. The hub shell and both collars come anodized in the same color, the axle is Silver. The color choices are Blue, Black, Grey, Green, Lavender, Red, or Silver. The weight of a 32 hole Bubba front is 121 grams.

The Super Bubba front is hefty version of the Bubba. Also machined of 7075-T6 aluminum rod. The hub shell is turned on a lathe to make it a one piece shell. The Super is drilled through, to hollow and reduce the shell's weight. Borings at each end make bearing seats to securely hold the bearings. The Super Bubba uses precision sealed cartridge bearings. A big design change is the axle. As noted, the Bubba uses an aluminum axle in the traditional 9mm outer diameter. The Super Bubba has been designed primarily with the mountain bike rider in mind, and specifically the Suspended mountain rider whose front shock fork is punishingly twisting the front hub. For this reason the axle, again machined from aluminum rod, is made with a 12mm outer diameter and an inner 5.25mm inner diameter. This produces a axle with a wall thickness of 6.75mm instead of the common 3.75mm. At the final 5.25mm of each end, the axle is turned from its 12mm diameter down to the necessary 9mm to fit into the fork blade. The Super Bubba uses machined aluminum collars which cover and enclose the bearings completely.
They are conical in shape with a 29mm diameter base that rests over the bearing and a 19mm diameter outer face with knurls that butts against the fork blade. Like the Bubba's collars, the Super front has inner O-rings in the collar to hold on and in place when the hub isn't on the bike. The Super Bubba front hub has a 50mm hub flange diameter, with flanges spaced 68mm apart. The larger diameter flange obligates you to shorter, stiffer spokes. The Bubba front spoke holes have a 42mm center circle diameter. The Ringlée Super Bubba front is available in either a 32 or 36 spoke hole drilling. The hub shell and both collars come anodized in the same color, the axle is Silver.The color choices are Blue, Black, Grey, Lavender, Red, or Silver. The weight of a 32 hole Super Bubba front is 158 grams.

The Super Eight cassette hub is the final of the four. It's a well executed easy to service by the user hub that has a freehub body with grooves spaced to fit Shimano or Shimano compatible cassettes, (SRP, or Action Tec). Like the three Ringlé hubs written about previously, this also has a one piece hub shell machined from 7075-T6 aluminum, and this one uses all the tricks at the same time. The shell is turned reducing the diameter between the flanges, but not as radically as the other three hubs. The dimension just inside of the drive side flange reduces very little because it houses a sealed bearing cartridge and the steel ratchet housing for the freehub. The hub shell is drilled through for the axle, and bored from each end to make a seat for the sealed bearing cartridge to butt against. A bearing is pressed to a 19mm depth into drive side of the shell. This shortens the span to just 50mm between this inner recessed bearing and the non-drive bearing, supporting the load more effectively. Once the recessed inner bearing is in place on the drive side a steel ratchet tube is pressed in place. The 13mm wide tube has its inner surface notched with small ramps that the spring driven pawls grip, to rotate the rear wheel. Shimano has a patent on the style of affixing the freehub that Shimano uses, which is to thread a 14mm O.D steel tube with a 10mm inner hex wrench though the freehub into the hub shell. The way Geoff Ringlé found around this patent is to use the freehub produced by Aerospoke. The steel, pawl bearing, freehub has three equally spaced, protruding, pawls on its inner side, which engage at once 120 degrees apart from one another.
The pawls are held in place, and kept in the raised-to- grip position by a spring surrounding the three. The interior of the freehub body houses two additional sealed cartridge bearings, which further support the load immediately at the outside of the hub flange, and again at 18mm from the flange. The axle is machined from aluminum rod and has a 12mm outer diameter which is turned down to the needed 10mm at the last 6mm of each end. The steel freehub body slides downs the axle and is held in place by a threaded collar that threads down the axle, pushing against the outermost sealed bearing. This threaded collar has a 19mm outer diameter with a serrated face, and comes in contact with the drop-outs. Another conical shaped aluminum collar is used on the non-drive side. This piece covers completely and encloses the non-drive bearing. An internal O-ring, recessed in an inner milled groove holds the collar on tightly and prevents contaminant migration up the outer axle. The collar has a 19mm outer diameter, serrated contact face. We found the Shimano CS- M737 cassette didn't fit well on this freehub body, it rattled because there was an extra 3mm gap that occurs in the first four cogs, allowing the entire cassette to rattle laterally, (this may be Shimano's laying the ground work for 9 speed systems). However, we found HG-90, and the HG-70 worked quite well. The Super Eight cassette rear hub has a 54mm hub flange diameter. The Super Eight spoke holes have a 45mm center circle diameter on both sides. The Super Eight comes either with a 130mm long axle for a Road 8 speed system or a 135mm long axle, spaced for 8 speed Mountain use. The spacing of the axle relative to the flanges is different for the two systems, so when ordering this rear hub you must be specific about its use. The Super Eight rear is available only in a 32 spoke hole drilling for Road use but is available in 32 or 36 holes for Mountain use. The hub shell and non- drive collar come anodized in the same color, the drive collar and axle are Silver. The color choices are Blue, Black, Grey, Lavender, Red, or Silver. The weight of a 32 hole, 135mm, Mountain is 348 grams.
