Cantilever or V-Brake? Why We Usually Choose V-Brakes
Good Detour

The short answer
We don’t replace a working cantilever brake just because it’s old. A good canti, set up properly, can stop a bike very well—and few things look more at home on a 1990s mountain bike.
But when the original system is worn, incomplete, or about to become a paid “upgrade,” we usually fit V-brakes instead. Not because cantilevers are bad. Because an everyday bike should be easy to set up, easy to service, and easy to trust in traffic.
For most of our daily rebuilds, the DIA-COMPE VC733 V-Brake Set gives us the balance we want: a silver, period-friendly look with strong, predictable braking and much less fuss.
The honest case for cantilevers
Cantilever brakes have earned their place on old mountain bikes. They look right, leave generous tire and mud clearance, and can perform extremely well when every part of the system is working together.
If your bike already has complete cantilevers, compatible short-pull levers, good cable hangers and serviceable pads, keeping them may be the simplest and least expensive choice. We would rather install fresh cables, fit good pads and tune an original brake than sell you parts you do not need.
There is also an aesthetic argument, and it is a good one. A polished cantilever brake, a tidy straddle cable and a slim old-school lever can make a vintage build feel exactly right. For a restoration or a bike whose original character matters most, that may be reason enough.
Where the cost starts to grow
The calculation changes when the system is incomplete or worn out. A traditional cantilever setup needs more than two brake arms and a cable.
- Cantilever or V-brake posts on the frame and fork
- Compatible short-pull brake levers
- A cable hanger or stop above each brake
- A straddle cable or link wire and yoke
- Correct cables, housing and brake pads
- Rims that are clean, serviceable and reasonably true
The brake posts are not the problem—most V-brakes use those same posts. The extra complication is everything above the cantilever arms. If the fork has lost its front hanger, the rear cable stop no longer suits the build, or the original short-pull levers are being replaced, the parts list grows quickly.
Then comes the setup. Pad height and toe-in matter. Both arms need to return evenly. Straddle height and yoke angle change the brake’s mechanical advantage, so a small adjustment can change both lever feel and pad clearance. A skilled mechanic can make cantilevers feel excellent. The question is whether that time and cost make sense on a bike built for work, groceries and weekend rides.
What riders keep saying
Discussions among experienced riders are usually split in a useful way. Cantilever fans point out—correctly—that a well-tuned set can stop hard, clear wide tires and preserve the bike’s original look. V-brake users answer that direct-pull brakes are easier to install, easier to center and easier to keep working well.
Both sides are right.
If the cantilevers are already complete and working, changing them may buy very little. If you are hunting for hangers, link wires, compatible levers and shop time, a V-brake conversion often becomes the more practical rebuild.
V-brakes are simpler—not automatic
A V-brake conversion still needs to be checked before ordering parts. Standard V-brakes require long-pull levers. Pairing them with ordinary short-pull cantilever levers can produce the wrong lever travel and braking feel.
Rear cable routing also deserves a look. Some older frames were designed around a centre-mounted cantilever hanger and do not provide a convenient stop for a V-brake noodle. In those cases, the clean solution may be a different cable stop or a run of full-length housing. Bikes with combined brake and shift levers can cost more to convert because changing the brake lever may also affect the shifter.
The cheapest conversion is the one confirmed before the parts leave the shop.
Why we use the DIA-COMPE VC733
The VC733 is our answer for riders who want straightforward braking without making an old bike look overly modern.
Its slim, silver-anodized arms sit naturally beside polished stems, seatposts and cranksets. DIA-COMPE uses cold-forged aluminium arms, linear springs, dual spring-tension adjustment and replaceable S-pads. The front and rear versions are purpose-specific, and each brake weighs roughly 186–188 grams before cables and levers.
More important in daily use, the adjustment is easy to understand. Set the pads correctly on the rim, centre the two arms, tension the cable and confirm lever travel. With compatible long-pull levers and healthy rims, the result is strong, predictable braking that is also easier for the next mechanic—or the rider at home—to maintain.
You may see DIA-COMPE describe the VC733 as a “long-arm canti” in some English material. For compatibility purposes, treat it as a standard direct-pull V-brake: it needs V-brake/long-pull levers.
Check these before you order
- Brake mounts: the frame and fork need cantilever/V-brake posts.
- Levers: the VC733 needs compatible long-pull levers.
- Rims: the braking surface must be clean and usable, and the wheel should be reasonably true.
- Cable routing: check that the rear housing can reach the brake cleanly without tight bends.
- Controls: note whether the existing brake lever and shifter are separate or integrated.
- Clearance: confirm tire, fender and rack clearance around the brake and cable noodle.

The bottom line
If your original cantilevers are complete, in good condition and stopping well, keep them. They look great, they belong on the bike, and replacing working parts is not our idea of an upgrade.
But if you are already replacing levers, missing cable hangers, sourcing straddle hardware and paying for a careful setup, we usually stop there. The DIA-COMPE VC733 keeps the silver, old-school character while making the bike simpler to tune and easier to live with.
Keep the bike. Change what matters. Ride it longer.
