The short front hub CRG 17 mm high precision aluminum is a part of the manufacturer origin (Original CRG Share), specially developed for the chassis of the range Mini (Mini 60, minimal, cadet) of the group CRG (CRG, Maranello, Dr. Kart).
The "short" version of this hub is an essential setting piece to refine the behavior of your front train. By reducing the contact and clamping surface on the rocket, this hub brings a greater mechanical flexibility by the front train, offering the young driver a brighter direction, a more incisive train and better registration in tight turns. CNC machined in a high quality aluminum block, it guarantees maximum strength for minimal weight.
The hub is delivered mounted and includes:
The short hub body high performance aluminum.
2 high precision waterproof bearings (Inner diameter of 17 mm) already inserted.
The internal spacer calibrated for perfect alignment between the two bearings.
Fixing studs to receive the rim before.
* "Hi young champions and mechanos! This short hub of 17 is the piece to have in its toolbox when the track begins to have a bad grip and that the kart tends to saturate or refuse to turn in the tight.
My trick for mounting at the top: clean your rocket axis to the brake cleanser before putting the new hub. Then apply a very fine lubricant film type WD40 or a very fluid fat. It avoids that the bearings do not lock by electrolysis or with moisture on the rocket axis.
And when you tighten your rocket nut, make sure that the hub keeps a totally free rotation. If there is any hard point or if it stops instantly when you launch it by hand, it is that your spacing rings force too much on the shoulder of the bearing. We want the perfect freewheel to release horses in straight lines! "*
Place the kart on its track trolley. Unscrew the 3 front wheel nuts and remove the rim. Then unscrew the safety nut (often puffed) at the end of the axis of your 17 mm rocket.
Remove the old hub as well as the track spacing rings. Pass a degreaser on the rocket axis to remove brake pad dust and gum residues.
Arrange your spacing rings on the axis according to the desired front channel width. Apply the trick to Michel (light lubrication), then slide the new complete hub CRG on the rocket.
Replace the thrust washer and the rocket nut. Tighten the nut firmly while making sure the hub is ultra-fluid. Do not forget to put the safety pin back on the rocket nut before moving up your rim.
Q: What is the difference in behavior between this short front hub and a long hub ?
A: The short hub gives more flexibility to the rocket, which releases the front train and makes the kart more agile and responsive when the turn trigger. The long hub, as for it, rigidifies the axis, which brings more stability in large fast curves but can make the kart heavier to register in tight pins.
Q: this hub CRG does it adapt on rims of other brands (eg OTK, AMV) ?
A: Yes I do. In the rim drilling, this hub respects the standard 3-hole standard distance (3x58 mm). So you can ride any standard front rim on the market. Just make sure your rockets are 17 mm in diameter (the mini / cadet category standard).
Q: Are the internal bearings waterproof ?
A: Yes, the bearings integrated with this complete hub are equipped with waterproof protection flanges (2rs) to prevent the track dust, sand or moisture from infiltrating into the beads, thus guaranteeing excellent longevity.

The front hub CRG 17 mm in size m (Medium) is a high-end frame of the original manufacturer chassis (Original CRG Share), specially developed to refine the guidance of 17 mm rockets (currents on the chassis of the categories Mini, minimal, cadet, mini 60).
The great particularity of this version lies in its internal architecture to double bearing. Unlike standard hubs that only use one bearing at each end, this model integrates two juxtaposed bearings on each side. This technique makes it possible to double the contact surface on the rocket, offering a Distribution of colossal loads and increased rigidity of the front train. By limiting the flexion of the rocket axis during large supports or passages on the vibrators, this hub guarantees a perfect and constant geometry of your front tires.
The front hub CRG 40x80 mm (R2.0 range) in black aluminum is a part of the original manufacturer (Original CRG Share), specifically developed to meet the extreme constraints of the Queen category chassis Kz (gearbox).

The CRG Kt2 is the versatile chassis par excellence of the Italian manufacturer. Unlike the Rébec Road (more rigid), the KT2 uses a frame compound full of tubes of 30 mm in diameter. This architecture offers controlled flexibility, ideal for freeing the engine in categories without gearbox like the OK, Iame X30 or the Rotax Max.
Its geometry allows fast adaptation to all track conditions (high grip or green track "). Featuring the last components of the range CRG RacingHe combines exceptional motor skills at a surgical front train accuracy.
The CRG KT2 2026 Version Kz redefines the standards of the Queen category. While the Road Rebel (32mm) remains the choice for the tracks with very high grip, the KT2 in 30mm Has become the favorite weapon of Kz pilots looking for more agility and ease in the support changes.
For 2026, CRG Reworked the composition of chrome-molybdenum steel to provide a better response from the front train during degressive braking. This KZ version stands out for its localized structural reinforcements and its integral front / rear braking system, essential to stop the power of 50 horsepower engines
The hub of 35 mm long is considered a "short hub". In karting, The choice of hub length is a fundamental adjustment tool:
Short hub (35 mm): It offers less contact surface with the axle than models of 75 or 90 mm. This usually allows to have a "freer" behavior of the rear train, Helping the chassis to be free from curve, Ideal on tracks with a lot of grip (adhesion).
The hub of 40 mm long is often considered the "standard" or "versatile" value on adult karts equipped with a 30 mm (x30, axle, Rotax, Kz, ok). Unlike very long (75-90mm) hubs that considerably rigidify the rear, or the very short (35mm) that fully freed the chassis, the 40 mm Offers neutral and healthy behavior, ideal for starting a setting session before refining.
