OK after today's ride and a little yard work (got to keep the better half happy) I finished step 1.... mounting the tubeless tires, disc brake rotors and cassette for my bike. It is the first time I have ever tried mounting tubeless so while they appear to be holding air now.... I'll have to wait until the AM to see how much my air loss is. The wheel sets came from Bike Nasbar their are Vuelta Corsa SLX 700c Discs and the rotors are TRP 33s front 160 mm and rear 140. The tires were purchased from Chain Reaction in the UK and are Schwalbe Pro One Tubeless sold as a set with both sealant and rim lube ( funny thing is they are both Stans NoTube products). After viewing a few online videos of the process I purchased Stans Yellow rim tape and an Airshot 1.15L Tubeless inflator to help pop the tire beads in place. It was a pretty simple process just waiting to see if in fact it works.....

Generally if they hold air they are seated .... only place they will leak is the valve, and if you didn't damage that inserting it .... you should be good to go. So

I followed your link from road cycling, where apparently, the rules are different.

Where are the bike pics? We need :"Befores" to have "Befopre and After"!

Plus we need a list of what you are adding ... and weights ... J/K

We'll friends showed up today so little time to do much. However on the plus side the tires are holding air. Got the chain sets installed along with new KMC 11 chains and replaced one of the hydro brake levers and bled the system. Installed the new wheel set on my bike and will give all this a try on tomorrow's ride on the Withlacoochee. I all goes well I'll set up the Wheelset for Mrs. DowneasTTer.

WOW! I used to get packages full of goodies like that. It was easier when my wife was working during UPS delivery time.

If there's no rain I'll be at the trail in the A.M. Hopefully we'll meet up again so I can get a close-up view.

WOW!!! I had my first ride on the new wheels and tubeless tire set up. My wife and I did our usual 30 mile ride on the Withlacoochee State Trail. It was a marked improvement over the OEM stuff. No air loss in the past 3 days so I figure that's good. The comfort of the tires running at 80 psi is a vast improvement over the ride on my usual Conti 4 seasons on the same ride. I guess I will be a tubeless guy for the remainder of my riding days (ok, I"m currently 69 so how many are left). The wheel set Vuelta Corsa SLX from Bike Nasbar is also a great improvement over the stock Giant PR-2 disc wheels. With the tires, wheels and discs the new setup is about half a pound less. It was quite noticeable when going up a couple of the small hills. I was even able to pass my wife!! Now that will end as soon as I upgrade her ride.

After the ride I was able to set up the Wheelset for my wife's CoMax. If the air pressure holds I'm put on her bike for a test ride in the morning. Also replaced disc pads, brake levers and bled all the brakes before a little pool time and a beer. Have a safe and wonderful holiday!

I love upgrading my bikes and customizing them to my preferences. One of my bikes is so modified it's barely even the same bike as when I bought it, sort of like the Ship Of Theseus. Or perhaps the Bike Of Theseus?

And now the rest of the story:

We purchased these bikes back in the fall of 2015. Since then they have been around 30k miles (yes we ride alot for a couple of old folks in our late 60’s) and have lived off the back of our motorhome for 4 months of the year. Upon returning from our summer travels to the North East the bikes needed to have several parts replaced or replace the entire bikes with something else. The drivetrain was simply worn out. Needing at the very least new chainrings, cassettes , chains and jolly wheels. Because of the time the bikes spend on the rear rack exposed to the elements many spoke nipples were breaking due to corrosion. So they really needed to be respoked or a new wheel set purchased. We looked at the new Fastroad Advanced with all the latest tech. However Giant didn’t spec the bike well IMHO. So we figured we could replace all that was needed including upgrading from 105’s to Ultregra R8000s and new wheel sets for less than half the cost of new bikes.

We had done a few mods before this however. The first thing we always do is replace the stock saddles. The new ones are both Terry, mine a Fly TI and hers a Butterfly Ti. The Giant grips and bar ends were replaced with Egron GP3’s and the Giant skewers with Enve Ti road skewers.

As the first post picture shows the upgrades include Ultegra R8000 chain sets, front and rear derailleurs, and cassettes. The wheel sets are Vuelta Corsa SLX Discs with TRP 33 rotors and Schwalbe Pro One tubeless tires. I also replaced both sets of brake levers as the levers had quite a bit of wear and tear.

So far we have ridden about 300 miles on the upgrades and all is well. The wheel set and tires are the biggest improvement as they roll much better and accelerate quicker (the engines are the same old tired out ones however). The tubeless tires mounted on the new “tubeless ready” rims without any problems and continue to hold air as well as any tubed wheels we have had in the past. My onboard toolkit has changed thou. Less tools but a small tube of sealant, a valve wrench, and plug kit were added for use on that first flat….

So for us the decision to replace/upgrade instead of simply buying new bikes was a win. We both have better than new bikes that we love and the retirement account was drained a little less than expected. Here are a couple of pictures of the finished product. Oh and btw I’m thinking now that maybe some Shimano XT M8000. Disc brakes and Enve carbon fibre handlebars might be next.

What a fantastic thread, my Comax 1 is only 8 months old, so no need for upgrades yet, , but I know where to come in the future. Can I ask how much the upgrades were?
