Seems like a good deal. Available in black or silver (front & rear options). Free delivery & 2 year guarantee - can't see this would be needed but hey 2 years is better than 1.

2.02% cash back at top cashback

If you want the black set they are slightly cheaper at £54,89 ribblecycles.co.uk/shi…et/

Back break is available in black slightly cheaper at planet X - £23,95 including delivery - I'm not sure if this is a slightly different model due to BR in the name planetx.co.uk/i/q…per

Garb from the website:

  • Dual-pivot caliper brake with super SLR-EV design for quick linear response, increased rigidity and improved braking power
  • Must be used in conjunction with ST-5800, ST-6800 or ST-9000 STIs for correct leverage ratio
  • Enhanced brake arch proportions give a quicker linear response and increased power
  • Low profile outer cable stop position improves cable routing for reduced friction
  • Cartridge brake shoes for easy replacement
  • Convex washers on the brake shoes offer toe-in brake adjustment and easy alignment
  • Lightweight aluminium construction, with an anodised finish to preserve the good looks
  • Compatible with up to 28c tyres

I honestly can’t believe road bikes still use this 19th century technology


I commute with dual pivot brakes (6800) all season with Swiss top pads and the braking powder is more than enough in all weathers

In terms of disc vs rim its a bit religous, I mtb, road (has 105's, frame doesnt have mounts for disc or I would replace) and commute and my pereference even on road would be disc, rim are adequate but by no streatch are they as good as disc, thats not an opinion its a fact.


No it's opinion. Decent rim brakes can generate enough force to lock up a wheel at any speed at which point generating more force is redundant. Discs are good off road so you can go through deep water without compromising braking performance, you don't need that on road.

Cheap rim brakes do suck. These are not those. I still value my rims and fat comfy tyres too much to use them.
Same price at evans cycles.

It's always worth remembering evans will price match crc and you get £3 evans vouchers for every £1 tesco vouchers

Another sheep who insists on disc brakes? These brakes are more than good enough in everyday weather and dont need regular adjusting like disc brakes.

Been using these a while on one of my bikes they have pretty good stopping power . And definitely not 19th century lol yes they are rim brakes but the technology has come far . The dual pivot system gives alot of power and easy to adjust. Get some greens on in my opinion too

But v brakes are more than good enough for everyday use, thats a fact.

Plus they are easy to adjust/repair on the road if you need to with minimal tools.

I know friends with discs who say the opposite, that if the wheel comes out of true you can still ride with discs. But with caliper brakes you will notice very quickly if the rear is coming out of true and can quickly correct.

You can't compare it to car or motorcycle, is your bike as heavy or fast as a car or motorcycle, no, it's not so obviously it doesn't need discs.

When your bombing down a hill at 40mph in the wet then it does make a difference. It nearly cost me my life and I ride down that hill on a daily basis, with disk brakes its assured and with rim its not. Thats my experience and I would add that of a couple of mates who have switched after similar issues in the wet at speed. On the gentle hills and in the dry its not an issue.
2 years guarantee will certainly be enough. I'm still using my 1999 105 brakes. They will last for ever.

If professional riders can cope coming down the Alps or the Pyrenees with rim brakes I'm sure most people won't have any trouble coming down English hills. Dual pivot rim brakes will stop any bike quickly and smoothly as they are very efficient.

The main usefulness of disc brakes on road bikes is in encouraging new cyclists to take up the sport as they are considered trendy and modern even though they are heavier.
I think it must have something to do with the rims, frames and forks, lightweight 700c wheels, frames and forks seems be mainly this type of brake and when you go up to hybrids and mountain bikes with stronger wheels, frames and forks you get more powerful V brakes. So its probably about the force applied. Some of the gravel bikes can seem significantly heavier even allowing for the disc brakes than standard road bikes. Whatever it seems sensible to keep to what the bike was designed for.

Is that not testament to how good they actually are? a good set of dual pivot and decent pads, you'll be set for all weathers.
I don't see the point in discussing rim and disc brakes, for the people this deal is suitable for they're not going to be able to change to disc brakes anyway as the bike likely won't have the mounts, similarly disc brake users can't mount a rim brake.

Merlin cycles have a front black 105 caliper for £24:

As I doubt professional riders are tuning in to HUKD looking for brakes its a mute point, you may also have missed what happened in the Olympics in the wind and rain. I live in Scotland where its a lot more hilly and pishes with rain quiet a lot, hence when its like that the road bike with rim brakes stays in the bike shed and I use something more appropriate.
For £5 more you can get the Shimano Ultegra BR-6800
I like that there is 105 reviews for these ... er ... 105s

Assuming it's the bike below then no, it's a different type of brake:

And as for still using wheels.....
I brought a set of 105 5800 calipers for my Trek 1.5 Alpha and was amazed at the difference is stopping power over the old brakes.
I used 105 5800 Rear+Front for 4 years until a few weeks ago when my foolishness resulted in the rear breaking (breaking, not braking). It has since been replaced with an Ultegra 6800.

The 105’s are excellent callipers; despite living in Scotland where it’s often wet, these callipers could easily stop my carbon bike and me within two metres without being thrown from the bike. Not a single flaw to mention; if I hadn’t just bought a new calliper I’d jump at the chance for either the single or the pair at this price.
