Campy SR 11 Dual pivot brakes, 25 tires on Pinarello F8

[fh8425]

Hi All

Am getting an F8 and thinking of using the SR11 groupset. Will run Campy Bora One 35 (24.2 mm width).

Read some where in a blog that SR 11 dual pivot brakes(rear) will rub on 25 tires on the F8. Further reading on other info says that campy has resolve this problem in the 2015 line of the groupset by making more clearance for 25 mm tires.

Can someone who has tried please provide some info.

Thx.

I can provide a little info, although not definitive for that frame.

In general, a Campy dual-pivot brake can clear a 28 mm tire, but only if the location of the brake bridge allows. Certainly, problems have been reported with some frames.

In 2015 Campy changed the design of Chorus and below brakes for a little extra clearance, but not SR.

A single pivot rear (which is the configuration I prefer), provides substantially more clearance than the dual-pivot, and I feel sure would be OK.

Yes. Was told the single will be ok. Trying my luck here as i would prefer both to be dual pivot if possible.

I can't speak to Campy brakes but Conti 25s and Bora One 50s are fine with my F8. IF the brake bridge is the problem consider using a washer to allow for extra height between frame and brake.

Using campy single pivot SR rear brake and FMB Comp CX 25mm (that run big) on Bora 50. Clearance is tight but fine.

There was an earlier thread on this which I just found http://weightweenies.starbike.com/forum/viewtopic.php?f=3&t=129750&start=30

Don't have this exact set up… My F8 with ENVE 6.7's and 25mm tubulars (Veloflex Arenberg) clears without a problem with EE brakes. My wife's Pinarello 60.1 has dual pivot Campy SR, Mavic Ksyrium SR and 25mm Conti GP4000S clears with plenty of space left.

thanks guys for the feedback so far .. not conclusive yet.

Hoping someone whom has the same config like mine to feedback .... Anyway the wait for the F8 is 60 days and i am yet to order the SR 11 ...

my opinions. but that's what the internet is for, right?

1. differential braking just makes sense. your car has it. your motorcycle has it. it works better. it clears the rear tire better. and. it's lighter!

2. SR is God's way of telling you that you have too much money. Buy Chorus, it's virtually identical. Donate the difference. you will feel so much better about yourself.

My 2015 Litespeed T1 can't run 25mm tyres on my Bora 50C's as the SR brakes rub. I'm running 23mm's but they do come up at 24.8mm so feel good. The 25mm's I tried came up at nearly 27mm. Both tyres are GP4000 II

I will have my Dogma F8 with (latest generation) Bora Ultra 50 clinchers and the 2016 SR EPS v3 groupset in a little over a month.
I was planning on running the new Vittoria Corsa G+'s in 25c.
Will let you know, if you can wait that long.

After months of waiting for EPS V3, my bike in the above mentioned setup finally got delivered!
Corsa G+ 25c is not a problem at all.
Plenty of space left at the seatstays and chainstays, less so at the brake bridge, but still sufficient!
If the Corsa G+ 25's are worn, I think I'll try Conti GP4000SII 25's, I guess they come up even a little wider?
