Acor ABR602 long reach calliper brake



Great value stoppers for older bikes and budget builds.

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

What the scores mean

Good scores are more common than bad, because fortunately good products are more common than bad.

Acor’s long reach dual pivot stoppers are a good choice for those seeking inexpensive but dependable braking on winter trainers, fixers or commu-tourers. They won’t spoil the classic lines of an older bike built for 27" wheels but running modern 700c hoops either.

Forged 6061 arms might not be the stuff of dreams but the high lustre finish is generally very good. As might be expected the detailing’s generally pretty good but a few corners have been cut: they’ve been able to cheat discreetly on the polish here and there but nowhere you'd notice. Elsewhere you get nicely machined Allen key fittings and a smooth, shapely quick release lever which takes care of wheel removal and allows a bit of breathing space in the event of a buckle. Modulation and feel are surprisingly good, even with inexpensive levers, giving plenty of warning before they’d come close to pitching you over the top.

Beefy arms and springs and dual pivot technology mean stopping power is more than a match for older centre-pulls and light years ahead of single pivot side-pulls, inspiring confidence when tackling laden descents even without a pad upgrade. However, heavier riders or those regularly riding in the wet would be advised to substitute the hard pads supplied for something softer.

Longer callipers mean they’ll entertain larger clearances, stout rubber and full-length mudguards without looking “gappy” or spoiling the clean lines of minimalist builds. You wouldn’t spec them on a Storck but they might be just the ticket for cost conscious builds or modernising older trainer/tourers.

you could try running a set of BMX callipers? reach might be an issue though as they tend to be much longer than road ones. plenty of room for the tyre though  1

Hello Jules,

I have a fondness for the Steamroller having run one for a short time. You don’t indicate whether you are running it as a fixed or single-speed. However, in my experience 40mm rubber is pushing things a bit- 38 is about as big as I’d go.

Riding the Surly as a fixed with designs on 40mm, I would replace the stock fork with a budget cro-moly cross/touring model paired to a single V/cantilever on the grounds of clearance.

Looking at the Acor as tested I can imagine you’d encounter similar problems as per the Tektro. However, it has a 48-64mm sibling, which could be worth a punt given the asking price.

Might be worth getting in touch with the distributor ( asking if they've experimented with similar configurations...

Thanks, Shaun.

I'd like to keep the frameset complete, because I like it, so I'll keep hunting for some large clearance calipers. Even though I use a fixed gear I prefer to have both wheel brakes working properly.

I tried to find some better pictures from the ACOR website but there wasn't much there. If you by any chance have any more info about the other product you mention I would appreciate it.

A valid point John, although depends how we are defining an old frame- they were fine fitted to a couple of frames from the late 70's/early 80's. However, I can appreciate the thought of filing the seat-stay bridge on a 50's classic might make the blood run cold.

I'm trying to solve a problem with large tyres mechanically interfering with brake calipers. Could these long reach Acor's be the answer?

I have a Surly Steamroller with Tektro calipers. I can just squeeze in a 700 x 35c tyre but I would like to use even bigger tyres (e.g. 40c, with studs) during the winter.

The interference occurs between the top center of the tyre and the underside of the caliper arms. With the Tektro's the underside of the arms is considerably lower than the line of the mounting bolt. How is the same dimension with these Acor's?

Thanks for any help!

If they're allen key fitting, you'll still have to do some bodging to get them on an old frame though.

tektro's nut fitting long reachers would be a better bet unless you're happy drilling the frame you're restoring.
