Full description of the product (H1: Front hub KZ CRG 40x96 mm R2.0 Magnesium - Full)
The front hub CRG 40x96 mm (R2.0 range) in magnesium (mg) is the ultimate factory piece (Original CRG Share), Developed specifically for the Queen category Kz (gearbox).
With its solid inner diameter of 40 mm and its maximum length of 96 mm, this hub of the R2.0 series is designed to bring a extreme rigidity at the front train. The choice of magnesium instead of aluminum is a high-level technical choice: it reduces the suspended weight while offering exceptional properties of thermal dissipation, which avoids overheating your rocket bearings and stabilizes the temperature of the rims during the overpowering braking of the kz. The length of 96 mm offers a maximum lever arm on the rocket, ideal for literally planting the front ground train and get ultra-direct behavior in the sinuous.

- 3. Tip in Michel (the corner of the expert)
* "Hi the artists of the speed lever! There, we touch the very high-end. The 40x96 in magnesium is the hub that the race service goes out when the track slides, it's cold, or we need a train before hyper direct who instantly dead. Flying Floor.
Attention, magnesium is a noble material but hate moisture and dry mountings! My obligatory trick: clean nickel the rocket axis of 40 and apply a thin film of copper grease (or high temperature white grease). With the front brake discs right next door that hears red, if you go up that dry, the magnesium hub will spupy by electrolysis on the steel axle. To go out without breaking it, you will cry !
Another small detail of mechanic: in washing, do not use ultra-aggressive acid degrees. It attacks the surface protection of magnesium. A clean rag shot with a little bit of WD40, and your stuff will remain impeccable. "*
- 4. The assembly guide & maintenance: step by step
1.Dimony of security:5 min.Put the kart on trolley. Remove the front rim by unscrewing its 3 nuts. Unscrew the central security nut of your 40 mm rocket.
2.Nettoyage and inspection:3 min.Slide the old hub out of the axle. Meticulously clean the rocket axis and brake disc using brake cleaner and a soft cloth to eliminate all glued platelet dust.
3.Ajustement from the front way:5 min.Install your rocket spacing rings according to the desired width setup. Apply the trick to Michel (high temperature grease), then gently fit the new 40x96 mm magnesium hub on the rocket.
4.Verrouillage and sinking:3 min.Replace the support washer and screw the central rocket nut. Tighten firmly and imperate the safety pin. Launch the hub by hand to check that it turns ultra-fluid in the front brake caliper.
❓ 5. FAQ SEO (Frequently Asked Questions)
Q: Under what track conditions should you use this 96 mm magnesium long hub ?
A: The 96 mm hub is the longest of the range. It is used primarily to maximize the rigidity of the front train. It is the ideal choice on "green" track (slippery), in fresh weather, or when you miss a directional grip. Magnesium makes it possible to obtain this rigidity without flowing the front train with respect to an aluminum hub.
Q: Does this 40 mm hub adapt on a standard category kart (Rotax Max, x30, ok) ?
A: Not. The category karts without box (single Speed) use 17 mm or 25 mm diameter rockets. This 40 mm hub is exclusively reserved for large-diameter-specific diameter rockets of the KZ (gearbox) chassis equipped with manual front brakes.
Q: Are the 40 mm bearings of this magnesium hub replaceable ?
A: Yes, quite. Although the hub is delivered complete with its factory mounted bearings, these are standard wear parts. You will be able to replace them in the future using a traditional rolling extractor without altering the magnesium body.
