Différences between"HXR " and"classic" kit.


The use of the LIFT MTB kit requires a crank with a freewheel, it is neccessary if you accelerate without pedaling, with this system the arms are not dragging by the motor (see video at the bottom of page).
 
The kit can not work without this kind of system, that's why a specific crank is inclued with our kit.
 
There are two versions of the LIFT-MTB Kit: V3 CLASSIC and V3-HXR
 
The V3 "classic" kit is the same as V3 "HXR" in terms of engine and power.
 
Both types of kit HXR and CLASSIC , have both a freewheel system, whether the HXR or CLASSIC version the function will be the same, only the overall weight and prescision of the freewheel changes
 
Here are the details that make the difference between these two versions:
 

 

 


 The 4  Main specs for the "CLASSIC" crankset:

 

-1- ISIS axle chromoly steel, with axle size choice of shaft diameter. (22/24, 24 mm, 28.99mm, 30 mm)

Available in different lengths to be compatible with all frames (xc / enduro / dh / fat bike).

 

-2- DICTA chromoly steel free wheel 20 points of engagement per turn.

 

-3- ISIS 170mm aluminum cranks, laser graving.

 

-4- Weight 1025 grams

(value of the "classic" crank alone except kit 249euro).

 

The 4 main specs for the "HXR" crankset:
 
-1-Oversized aluminum axle, available in 30mm diametre only

 

 

-2-HXR freewheel with aluminum body, 108 points of engagement per revolution.
 
-3-Crank aluminum superlight 170 mm arms.
 
-4-Weight 775 grams (value of the crankset only "HXR" except kit 449euro).

 

Warning: only one length of the axle, this crank will not be compatible on the DH bikes with BSA 83 mm BB, press fit 107 mm BB or fat bike BB.

 

Warning: if you have another axle size diamètre of 30 mm on your bike, you must have to change the bottom bracket bearings for 30mm version(contact us if necessary).

 



Conclusion:
 
-With the HXR you will save 250 grams.

-You will have a better responsiveness, and it will be more precise during pedaling part's due to high range freewheel.
 
-The overcost will be 250euro For the HXR version compared to the CLASSIC version.
