Trek Domane SL6 vs Checkpoint SL6

Road Cycling ďIt 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.Ē -- Ernest Hemingway

Good point but it was in the 20s at the golden hour, and at that time I was otherwise engaged in warmer activities.

FWIW, this Varia mount fits the seat post fine. I use it on my SL5. Didn't know about the reflector, didn't get one with the bike.

Iíll have to try mine again. Though it is on a second bike now. Now that I think of it it should fit. But but but what about the gap left by the flat side of the D. Not sure 🤔 if I can like that.

With it mounted on the seat post (not the seat tube) the gap isn't noticeable. At least not to me.
Especially when riding.

Domane comes with 32 tires. Not sure why people are recommending 25, 28 or 30. You don't gain any speed with a smaller tire and you lose comfort.

The R2s that came with my SL6 were slow and stiff. I tried them. Had on hand a 25 and a 28 Conti 5000. Softer ride. The 25mm measures 27.5mm and the 28mm measures 29mm. A little wider than marked while the R2s are true to size. I do switch back and forth and use the R2s when there is more soft ground that needs the wider foot print. 32mm

Thoughts on how much of the difference was size rather than tire? i.e. if someone didn't already have Conti 5000's, would you suggest a size other than 32 and for what reason?

My plan for the next set of road biased tires is 28 or 30mm tubeless. Then a second set of wheels for road. Use the stock wheels for the rail trail gravel bias and go with 35 to 38mm also tubeless. I may chicken out and keep running tubes though. Need more road time to wear out tires.

Oh, I'm sure I'll try it myself in due time. Just curious as to what extent the size vs tire made the difference @biker128pedal observed since I haven't a lot of road tire experience.

Tires are consumables and, at these size differences, we're talking about more subtle differences - no reason not to try it yourself when your current tires need replacing. Even if you don't like the change, I don't think that the difference is going to be so vast that you would object to getting all of the mileage, and your money's worth, out of the tires.

For myself, moving to 28s (from slightly oversized 30s, by current standards) was a slight, but noticeable, difference in handling and comfort. I preferred the feel of a bit of increased agility, though some might think it increased "twitchiness" and not like it. The small decrease in comfort wasn't an issue for me.

With identical tires, or those of a similar class, the size difference is still going to have an impact: weight, pressure, profile - they're all going to make small differences. Whether those small differences are significant is up to the observer.

I have Conti 5000 25mm on front and 28mm rear mainly because thatís what I had. The 28 was on the shelf I bought and did not fit the Madone 5.0 I used to have. The 25mm was a spare for the Madone. Also the 25mm is more aero on the Domane stoke wheels. The 28mm on the front was just too wide. I even tried a 23mm I had on hand.

That explains a lot. The stock R2's are junk. That was one of my first upgrades on the bike. Got rid of the R2s and put on Conti 5000 32s.

Try the conti 5000 32's.

I've yet to have a new bicycle come with factory tires that were satisfactory to my riding needs. Just like a seat, the tires are expected to be immediately changed out.

They are rim protectors there for shipping purposes. Also to be used as spares when one gets a cut in oneís tire that cannot be repaired. Fold then up and out them away. Oh another use is on the stationary trainer.
