Planet X calipers

[Markp13]

Over the winter I ordered Planet X CNC lightweight brake calipers as a supposed upgrade to my shimano 105 setup. Well that wasn't half a mistake!!

The setting up of the things is a nightmare. I tried (professional
Electrical Engineer) then my training partner tried (professional Gas engineer, who recently built a Cervelo from scratch) and we both struggled to get them centred.

In the last week I've done 150 miles
with them, my first rides of the year and the stopping power is terrible. I mean so bad that you'd struggle to lock the back wheel if you chose to.

So, admitting defeat, I took it to my LBS, where the owner looks after some pretty high end TT stuff. Even he said they were a nightmare but he'd done the best he could. He recommends throwing them in the bin and putting my 105 stuff back on. His words were threre's not enough modulation with them.

Has anyone else had these issues with Planet X calipers? I'm half way decided to send them back but I'd be 100 bucks down.

Yes that's the ones. The centreing as you say was a real pain and theyre almost there now but they just don't seem to have much "power".

They almost feel unsafe.

Maybe I'm used to the bite the 105 gave me but I suppose this week will tell.

At the minute in just not very impressed

I've got a set of these on my pinarello, they are a pain to set up and the braking is pretty poor (probably the pads) but they look so good!

On my Tarmac it has 105 and it's night and day in terms of stopping power.

Annoying but I'll live with it.

I thought it might be the pads too, so I asked but he was certain it was the modulation.

They do look good in there anodised colours but they just take so much more effort for the same/or near performance as the 105's.

Anyone want planet x calipers for 50 bucks before I bin them?

I'll empty your bin for free.

Ideal, thanks, there's an entrance fee of 59 quid tho.

What colour? Could be tempted for the training bike...

Black with the red anodised catch.
