Wider road tires

['Dale]

If you are sub 70 kgs, 25c is the sweet spot

If you are above 70 kgs, 28c is better ⚠️

I am buying a new road bike, I have an amazing bike but.... the two biggest reasons for the change is, disc brakes and 28-32 road tyres.

Smart man!

Lol, if only 70kg was even in my vocab. I look like I'm malnourished at 85kg. But... you are right.

I am trying to understanding this roadie thing. If 25m is so much better, why did they invent 23mm tyres. Is like 26" mtb wheels?

 

Back in the day, the standard used to be 19mm tires at 170psi!

Times are a changin'

Have a look at Jan Heines Off the beaten track - Compass Tyres - if you would like to know more about wide tyres and performance. Theres a bit of self promotion there but its valid and interesting reading

i'm following this topic quite a bit... got a disc road bike last year and looking to buy some carbon wheels...

 

what struck me was the massive dimensional differences between the different brands.  UCI regulates the maximum depth, so no surprises there on the ~50mm...  But on the width (internal and external, ENVE's SES 4.5AR model is about 5mm wider on all dimensions compared to all other brands.

Will throw a spanner in the works, at Kona 2017 most of the top finishing triathletes rode on 23mm tyres https://www.slowtwitch.com/Products/Bike_details_of_the_Top_15_Kona_male_Pros_6639.html

 

Current thinking for speed,aerodynamics and comfort is 23mm front and 25mm rear.

is there anywhere in SA where one can buy 30mm road tyres?  slick tyres, not the gravel ones with mini knoblees...

I thought I found the ''sweet spot'' on 25's at my healthy  85kg and now some boys are talking about 28 and 30's!!
