ProsDurable, Versatile, Financially Economical

I've bought these brakes on a number of ocassions for lots of different bikes and they are excellent. They are great for anyone looking to convert to new 700c wheels on old steel frames and are one of the few new brake systems which fit well on old forks and rear brake bridges. The braking power compared to older brakes is also considerably better and they are rugged bits of kit, able to take a beating day on day without losing performance. On top of all this, they are easy to fit and can be fitted and adjusted in five minutes. Another great Dia Compe product!

Lots Of Drop And Lots Of Clearance

Prosprice, quality, appearance,

I bought this to fit to a Likeabike Jumper. It has just enough reach (pads are at the end of the slots) and plenty of clearance to get around a 2 inch tyre on a narrow rim. The return spring is quite stiff for little hands, but it fits perfectly, works as it should and looks great

Prossimple, functional, inexpensive

I've used these front and rear on a 1987 stainless steel dahon classic. I got them for two reasons, firstly because they are very deep drop, and secondly, because being side pull they tidied up the over complicated cabling from the old centre pull brakes (it's a folder after all). I immediately replaced the blocks with good quality cartridges, so i can't comment on the original set. With that upgrade in mind, i'm really happy with them.

Useful For The Long Drop, But Pads Not Amazing.

Prosgood value,

Good to be able to get long reach brakes for reasonable price, and as others have mentioned nut mounting is good for older frames.

Found it difficult to align one of the pads however, so I replaced them with another set.

Prosstrong, light and easy to fit

Excellent, works perfectly and has got the wife back out on her bike. Other shops were asking £50+ for calipers with this reach. Great item thanks

Prosprice, performance,

Excellent brake caliper for the money. Light and powerful. Has enough reach and nut mounting to suit an old frame.

Questions & Answers (7)

Is there a minimum rim width recommendation for these?

By Val

17 Aug 2017

SJS Customer Service:

Hi,

There is no official minimum rim width recommended for these brakes, but we'd suggest not using on rims any narrower than 19/20mm.

Thanks.

Compatibility With Rims...

By Will

06 Jul 2017

Hi. Would these brakes be compatible with rims with an external width of 25mm?
thanks.

SJS Customer Service:

Hi,

These brakes would be absolutely fine with use on rims that measure 25mm externally.

Thanks.

What Is Length Of The Bolt On Front And Rear?

By Val

13 Jun 2016

Is it possible to use on frame for recessed fitting (rear)

SJS Customer Service:

Hi,

These brakes are normally designed for use with a nutted fitting rather than a recessed bolt. The rear bolt is 33mm long and the front bolt is 51mm long.

Thanks.

What Brake Blocks Fit These Brakes And Do You Stock Them?

By Haydn

29 Apr 2016

SJS Customer Service:

Hi,

These brakes use standard Shimano style calliper brake blocks so any blocks that use the Shimano pattern can be used.

Thanks.

Front & Rear Differences

By Neil

02 Jun 2015

Is it just the length of the bolt?

Can I buy the bolt separately?

SJS Customer Service:

Hi,

Yes the only difference between the two is the length of the bolt. The bolts are not available separately I'm afraid.

Thanks.

Hi, Do These Dia Comp Callipers Fit A Brompton?

By Peter

23 Apr 2015

Do they have the correct drop to fit a brompton front and rear. (I suspect I may need to make alterations to make the actually bolt on correctly)
Thanks, Peter.

SJS Customer Service:

Hi,

They are right on the limit of the drop required for a Brompton as they usually require about 60mm of drop for the front and 55mm for the rear. The other issue with fitting these brakes to a Brompton is that Brompton's run the brake cable the opposite way so the cable clamp and guide/ barrel adjuster are in the incorrect place on this brake.

Thanks.

How Is The Drop Measured?

By Anonymous

30 May 2014

From the frame fixing bolt to the lowest setting or is it the setting in the brake block slot

SJS Customer Service:

Hi,

The drop is measured from the centre of the frame fixing bolt to the centre of the brake pad fitting bolt.

Thanks.
