Ratchet
NEW DT SWISS EXP RATCHET COMES WITH BELOW BENEFITS:
1.SIMPLE MAINTENANCE:No tool technology,make maintenance even simpler

2.FREEHUB BODY CONVERSION:Simplified due to easier disassembly.

3.LESS WEIGHT:Not only the reliability improved. The fusion of ratchet and threaded ring reduces the number of single parts of the system, which offers an important advantage.

4.LESS WEAR:A single cylindrical spring ensures faster full engagement and thus increases reliability.

5.SUPERIOR RELIABILITY:The full engagement of the ratchets creates a large contact surface and therefore low surface pressure that leads to superior reliability.

6.INCREASED BEARING LIFETIME:The integration of the bearing into the threaded ring allows the bearing distance to be maximized. The increased distance further supports the axis, which results in less deflection of the axle and thus protects the bearings and increases their lifetime.

EXP 36 - With only a singlel spring, making the hubs faster and lighter, more complete engagement of the 36 ratchet teeth for more precise contact, and therefore a longer lifespan.

EXP 54 - Upgraded from EXP 36 to gain incredibly faster engagement.

Application

All Mounttion: AM Enduro: DH Down Hill: DH
All of our EIE rims share the following manufacturing technologies:

1.Super light Weight

T700:The standard XC/AM/DH version were constructed Premium Toray T700 Carbon fiber.

T700+T800 component:The super light series EIE carbon rim were constructed with properly component of Toray T700+T800.We cut the material size of the nipple bead area and strengthen the key parts of spokes to maintain the strength of the overall carbon rims.

2.Layer-up

The layer-up of each carbon rim is carefully designed, repeated tests and then determine final standards document. After that,we’ll send it to our layer up workers, who operate according to the operating standards.

They cut the size of the material according to the layer- up instructions to produce materials for any part that can be used to increase the strength of the side part of the wheel set, to fit the grooves of the rims, to enhance the impact resistance of the wheels.

All EIE's carbon rims were manufactured by a one-piece continuous layer. This uninterrupted layer not only produces a stronger rim, but a lighter one!

3.Angled Hole Drilled By CNC Machine

The spoke hole angle design of the rim is very important , but its design angle range is limited .

If the design does not match the design of the spoke hole angle of the hub , the bending phenomenon of the spoke can be generated .

When our EIE carbon rims drill angled holes, the spacing and angle of each hole are calculated accurately to ensure that when the rim is connected to the drum through the stripes, no additional pressure is generated around the rim hole.

We use a high speed CNC machine to drill all the holes to avoid spoke holes area carbon fiber strength reduction ,thus making the wheels build stronger

4.Smooth Rim Inside Surface

The air bladders are made from a special material which has ability to produce very smoother walls, result in a lighter rim, and are completely removed without harsh chemicals.

They are removed through the valve hole with a unique process by a skillful workers .So you would not see any patched hole on rim bed,that produces a stronger rim.

I will be using this rim for offroad touring with a 27.5x2.8 inch tire. I am having trouble deciding if I should use this product (A29C39D25) or the symmetrical equivalent (S650BC38D30). I am 70 kg with up to 45kg of luggage.

EIE EIE Carbon:

@Lyle Thank you for your inquiry. The size of model A29C39D25 is 29er. If your tire size is 27.5 inch, we don't think they can be fit，so this model S650BC38D30 is more correct for you. Hope my information helps you. We have sent an email to you to discuss more details, please check it. Thanks, EIECarbon

Can I use nipple washers with this rim A29C39D25 to increase the strength? The nipple washers would be DT Swiss PHR. Would that be needed for the S650BC38D30 rims?

EIE EIE Carbon:

@Lyle Thanks for your inquiry. All EIE rims can be built without washers .For sure,it will be no problem if you want to use washer to build. So DT Swiss PHR washer can be used to our rims. Hope my information helps you. Thanks EIECarbon
