SLF Hyperspeed System Review & How To Install – Part 2


Checkout Part 1 Here 

For part two of our SLF Motion Hyperspeed System review, we'll be diving in to the install of the kit on your rear derailleur.

As a disclaimer, this writeup is NOT intended to be the "end-all be-all" installation guide NOR replace professional installation. We always suggest having your work done with a local professional bike shop or builder OR at the very least checked over by them. Safety first for riding gear!


Estimated Completion Time:
15-20 minutes (bench work only)
20-25 minutes (chain & derailleur removal & reinstall)

Difficulty Factor:
4 out of 10 (requires some patience)

Parts Required:
1x Hyperspeed System Kit (can be purchased here)
1x Rear Derailleur (Ultegra 6800 in our example)
1x New Chain (extra links or length - 118 is a good starting point depending on gearing DON'T PRE CUT IT)

Tools you'll need:
Flat Head Scewdriver (smaller in size)
Allen Wrenches 5mm, 3mm, 2mm, 1mm
Loctite (purple or blue) OR "Plumbers Tape"

Optional Items - But Highly Recommended:
A clean workbench
Small Dab of Grease (standard automotive grade is fine)
Latex or Nitrile Gloves
Patience


Step 1 - Remove your old chain & the rear derailleur from your bike. If you don't have the tools and/or skills to do this, stop reading and take the kit to your local professional for installation.

Step 2 - Layout all the tools, parts, kit pieces and components on your clean workspace. There's no point in starting a teardown if you don't have everything needed to complete the job.

Step 3 - Remove the RED stop screw on the new SLF kit. This gets re-installed later on. Remove NO other screws on this front/outer face of the kit at any time.

Step 4 - Remove the upper jockey wheel / cage bolt from the stock system. The pulley will drop out. Set it and the bolt to the side.

Step 5 - Rotate the stock cage out of the way to access the main mount bolt for the wheel systems. This will take a little bit of torque to loosen up. As you unbolt, be sure to keep a solid grip on the assembly as the internal spring pressure will want to push things apart quickly.

Step 6 - Take note of all the internal pieces that came out. Everything is reused EXCEPT the stock washer-spacer. DO NOT REUSE THIS!

Step 7 - Take note of the inner spring tab alignment hole. Now is a good time to add a VERY small dab/coating of that grease to the mounting bolt and inner spring mounting area so nothing runs the risk of seizing down the road.

Step 8 - Flip your Hyperspeed System over and remove the back facing bolts. Take care as these are TINY. Make note of the wheel orientation/direction and set those aside. Be careful not to loose their special red center spacers.

Step 9 - Insert the stock mounting bolt through the mount hole (on the new system), place the NEW supplied spacer on top and ensure the small "black ring seal" is seated in place as well. Set this aside for a moment.

Step 10 - Install the spring into the derailleur opening, taking careful note to line up the tab with that inner hole from earlier (red arrow). This can sometimes take one or two tries as it's done by "feel". You'll feel the spring gently drop/click/slide into place once it's right. Don't move on until the spring is definitely seated correctly with the inner tab.

Step 11 - With the spring dropped in place, grab your new Hyperspeed frame and install. Ensure the spacer and "black ring seal" stay in place. Be sure the spring also lines up with the ONLY opening on the Hyperspeed red mount collar. Tighten the mount bolt down so it's snug (don't go nuts here, just make sure it's snug).

 

Step 12 - This is a little tough with one person, so BE PATIENT! You'll need to rotate the arm around (under spring tension) and reinstall the RED stop screw with your flathead screwdriver. Take your time and go slow as you don't want deflection while rotating the arm (this can bend and/or damage the cage system). Patience!!

Step 13 - Reinstall the wheels (hope that orientation was noted OR photographed from earlier) and the back of the cage. Use a VERY tiny dab of Loctite (purple or blue) OR a small amount of "plumbers / thread tape" on the bolts to ensure they won't vibrate loose. DO NOT USE Loctite Red!!

Step 14 - Admire your work! Check the fully assembled unit for free & smooth actuation prior to reinstalling on the bike.
