25c Tyres on a Dogma 2 frameset

[Aurora]

I have just got a set of Vittoria 25c road tyres that I have fitted to a set of Campy Eurus 2-way fit wheels.

On the flats, the setup works perfectly.

 

As soon as i stand up to sprint or climb, the tyre rubs on the frame just behind the rear brake caliper.

 

It has got to a point now where I have reverted back to a 23c rear tyre.

 

Anybody else have any experience with this?

 

I have read that the frame accepts 25c tyres so just wondering what might be causing this issue.

Perhaps the wheel spoke tension needs checking

Not all frames can take 25 and bigger.

But that sounds more like a dodgy wheel, or a wheel not suited to your power.

I have tbe FP3 with 25mm. Rear clearance is perfect at 8 bar but on the front I only get around 2mm clearance at 7.5. Have considered going back to 23mm.

could the issue not possibly be your wheelset and tire combo

 

the internal diameter of your wheels and your inflation value can affect the amount of distortion of your tire under load (sprinting ,fast hard cornering etc )

 

your Eurus 2-way fit wheelset is designed for a specific setup

 

therefore if you deviate from the specific setup and tire choices the tire you are using may not seat correctly or it may distort enough under load to touch your frame

 

the psi you run it at may affect this also

 

I had a similar annoying thing with my de rosa and a set of wheels and tires I got for training - it may not be your frame that's at fault

 

but hey what do I know anyways

Hi, seems I encountered the same.

I have 2 dogmas

1) Dogma 2

2) Dogma F8

Both are in Size CC500

 

Every time I use 25C tyres, the rear clearance are very less and because the tyres are not very well in balance and some of it will touch the rear top or the stay.

 

The example are also fall into this issue

1) Camp Bullet with GP4000S2 25C

2) Racing Zero carbon with 25C pro one tubeless. (I modify it)

 

But I seems found there is not all Dogma encounter this issue and pnly size 500 will have this issue.

 

Is your size is CC500?

My frame size is a size 53cm.

I have performed some matching also today

I found I using a Fulcrum Racing ALU 2-way fit, 

with Schwalbe One Tubeless 25C and the clearance is just fit for my bike

 

Next, a Racing Zero ALU with Continental 4 Season 25C is fit as well

 

Also I found 25C tubular Tyre mounted on Fulcrum carbon wheels are also ok

 

means not all tyres are not compatible.

Hope this help.
