Great to see a build that's not full Dura-Ace DI2... Thanks!

[petinka]

That video came in perfect time! I have plan to put a new group-set on my bike!

State-of-art technology, every biker should be grateful of what we can get today ! Thank you for showing all the steps and procedures.

I always like to add an in-line barrel adjuster to the cable housing for the front and rear derailleurs so I can fine-tune while riding. Seems I only notice/remember shifting problems while riding so these become crucial. Also comes in helpful if you race and need to grab a neutral support wheel.

[eboro]

Braze on derailleurs have support bolt and backup plate, You should mention that too!

[fennec]

nice vid. Its good to see more talk about Mech drivetrains. Di2 is cute and everything - but I have never had my
mechanical groupset run out of battery on a long ride and had to pedal home in whatever gear it decided to be in.
Mechanical has less to break or go wrong, is cheaper and less maintenance.

Thank you for this very precise tutorial in setting-up the group set of the road bicycle .

[KenSmith-bvsi]

Thankx Alex, and just so you know torquing to the correct value is really important. When I was phixin Phantoms(1976) everything was torqued, some had to be "witnessed", so to this day I always use a torque wrench. Now go back a re-torque all them elbow settings to the correct value.

Perfect timing. I’m just about to upgrade to shimano 105 r7000 parts!

[seniorcycling]

Helpful hint for those front mechs, on the left side there’s a line on the mech and where the pivot point is, when you shift into the big ring if those lines are perfectly in line you have the perfect amount of cable tension. If the pivot line is lower, add tension, if it’s higher, remove tension. It’s a great and useful feature Shimano thought well to include.

[WahyudiWidodo]

For the FD there's two lines that you have to align while in the shifter is in trimmed position from big to small chainring.

[jakehenry]

I have always set up the front derailleur before the rear. I also tend to put the chain on the big ring for indexing.

[awakenedbahamut]

Perfect, I am currently trying to figure out how to install a derailleur and cable on my commuting bike!

[JMcLeodKC]

Which costs more, a 105 mechanical group OR those Park Tools required for installation?

[philipaddyman]

Didn't know about that little cable tension 2mm screw on front mech ... thanks.

[SteelyDad]

I have messed with this stuff a lot but I never knew about that “b limit screw”.

[andrewlipsiner]

Reasonably good installation video
Was wondering about chain install
I have always run new chain on SMALL Chainring, feed thru derailleur and on SMALLEST cassette to determine length
Was also hoping to see a more detailed bit on installing chain pin and cutting here
Nothing here about the most complicated and dirty part of hydraulic brake install..adding brake fluid and bleeding system properly ...
I ' m sure there is a separate GCN link for that

[andreasr]

Haven’t ever had any serious issues with headsets or brakes but i always get the BB faced cause if the dreaded creaking noise starts coming from down there i can literally set it on 🔥.

[fabianbv]

I would appreciate if you could prepare a video explaining which is the best grease, paste, oil or similar in each part or the bike and depending on the functionality or materials... Great video though!

Generally I find that putting the chain onto the second-highest gear before doing the pinch bolt works best for the reach mech. I usually still need to do a handful of clicks on the barrel adjuster, but if I do the highest gear I used up most of the barrel adjuster's range right off the bat. I think one of Si's video's put me into this a few years back.
