Turning a Domane SL6 into a SL7+

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Turning a Domane SL6 into a SL7+

The outdoor riding season is over for me so I decided to start the upgrade process on my 2020 Trek Domane SL6. First I changed out the mechanical for Di2. Did the work myself and it went without a hitch. First time doing a conversion so it took longer than expected. Still need to fine tune the system and bleed the brakes. Today I picked up a new longer stem, and Bontrager Aeolus RSL V's for the ultimate upgrade. With the Dura Ace cassette and Rene Herse tires, I saved 773 grams over stock. Should make the bike feel lighter which is my goal.





So now it is closer to the SL7 but with even better wheels than the stock Aeolus Pro 3's, so I am calling my bike the SL7+. It will be my trainer bike for the next few months and I won't get to experience the full feeling until spring. The only thing it needs are Dura Ace discs for a better colour match. the white fins on Ultegra look out of place.

Nice job!

I've got a similar setup here in Ottawa on my 2020 SLR7. Opted for the RSL 37Vs to shed a bit of weight too. I've moved away from the Rene Herses now, mind you, in favour of 30C Schwalbe Pro Ones tubeless. DA rotors are a nice touch

SkepticalOne , blakcloud How do you both like the RSL 37Vs? On the verge of pulling the trigger on an SLR7 with the addition of RSL 37Vs in place of the Aeolus Pro 3Vs.

Since we are getting all fetish about this, go with the XTR Rotors. Lighter and in my opinion better looking with enough black accents to work with your setup. Could also paint you Ultegra rotors with high temp flat black.

Looks great! I have an SL5 that I'm considering upgrading to Di2 - would you share what size your Domane is, and what cable lengths you ended up going with to connect the various pieces? I can't tell from the pictures - did you use the bar-end junction box? And did you use the wireless module?

Where did you put the battery? Is it in the downtube under the water bottle next to all the hoses and such?

Since the bike is only 1 year old, wouldn't it of been cheaper to buy a SL7 in the first place? Or were the finances just not available then?

Did you sell the stuff you removed to recoup some of the cost?

When i upgraged from Sram Red 22 mechanical to eTap I sold off the the shifters and derailleurs and my final cost was $900.

My SLR7 has the battery in the downtube and the junction box in the bar end.

My bike is a 54 cm. For wire lengths I found that information in the Domane Manual on page 10 section 7. It has all the lengths needed. I did use the bar end junction box and the wireless module.




I made my own colour coded diagram to keep things organized.

Yes, the bike already had a battery holder as in the diagram above. You unscrew it from under the downtube, pull it out and put the battery in and tighten it down. I did have to remove the crank set and T47 bottom bracket to fish the rear derailleur wire to Junction Box B.

I do have a pair of XTR rotors on my custom and when they heat up they make that zing zing sound until they cool down. My thinking is that the cooling fins on the road versions seem to help in this regard. At least I haven't had any of the same noises on this bike.

They're super premium in their finish and scuff a bit but are absolutely top notch. I find they ride more stiff than my ENVEs and dial the pressure back a bit. I'm running 30c tires at around 58psi and they are just superb o the descents. Gorgeous hubs and not as noisy as my 3Vs - also much lighter.

I have not actually tried them yet so I can't give an opinion. I need to set up the brakes and I am having a harder time than it should be but I attribute this to first time blunders. They do like nice though and I like that I have the option of using hook beaded tires. Glad to hear you like yours.

Your bike looks like my bike's twin brother

With the Dura Ace cassette, I'm assuming you changed your gear ratios? I considered going down that route as well for weight savings, but I really like the stock 11-34t cassette for the terrain where I ride. Looks like an 11-30t is the largest range in Dura Ace. XTR cassettes have more range, but still no 11-34t.

With the smaller cassette, I'm assuming you also went for the short cage rear derailleur instead of the medium cage that comes on the SL7?

The typical riding I do never needs anything more than a 28 and as you mentioned that is the biggest you get with Dura Ace. Weight savings was a consideration. I went with a medium cage on the new build because I knew I would need it for riding in the mountains of Japan. I kept the original cassette and the plan was to use the medium cage with the large cassette for the next trip. Unfortunately I don't know when the next trip is going to happen because of the pandemic. Going with the medium cage won't hurt in anyway even with my smaller cassette, it just doesn't look as good.

I would recommend against trying to move in a direction other than comfort for Domane bars. The bike is made to keep you comfortable over very long hauls and so a bar with greatest comfort (isocore) and most forgiving hand positions would be my recommendation. And then a professional bike fit.

Here are the Aeolus RSL 37Vs on my SLR7 covered in road salt yesterday...

I wouldn't rule out aero bars.
I have the carbon 3t aero nova on my Giant Defy and for me they are very comfortable.
I like the flat tops and also the bars are quite flexible in the vertical plane and subsequently are excellent at absorbing road shock/vibration.

I agree in that I really could care less about the "aero" part of the Bontrager XXX aero bars on my Domane. I like having the flat tops for resting my hands during climbs or my elbows when I ride in a pseudo time-trial position.

I cheated, since I really don’t know how to work on bikes. I went out and bought the SLR7..........but I did put on the Bontrager decals.
