Replace Caliper with disc brakes ?

I canít justify a new bike as the one I have is basically what I want ó with one exception.

having experienced disc brakes, I want them !! (I donít know if my holiday rental had air or mechanic discs).

Is it worth replacing my callipers: eg what is involved ? Presumably I can keep my wheels and brake leavers ??
my question is really how much is involved and how to ďdraw the lineĒ of new stuff but be confident things will all work together.

FYI, my bike is. Decathlon BTwin Riverside 500, 6 years old. Their 2020 model has discs, and although I could afford to replace entirely, it just feels crazy when Iím basically happy with what I have,

Mike.

Does your existing frame have mount points for disk calipers? If not, you'll find that it will be a significant challenge (i.e. not worth doing). What's more, if your fork is not designed to handle the torque of a disk brake, it may be dangerous to adapt it.

Good luck to you.

I have a question about this. I want to change my ancient Disc Magura Clara Caliper to something modern. I can't figure how to get the pads out.

I will start a thread about it.

It's way easier and cheaper to trade in your bike for one that has discs to begin with. If your bike has the tabs for the disc caliper then it's certainly possible. But there are more parts involved than you hope. You need to replace the hubs. If you don't know how to build wheels then you will have to pay someone to do the swap and it would probably be cheaper just to replace the wheels. You need to have not just the calipers but the discs and adapters, and replace the cables with longer ones that go all the way to the hub. If you want hydraulic that's the levers too.

Just a thought, and not what you're asking, but the existing brakes could be overhauled or replaced with higher quality. At the very least, 6 year old pads could be dried out, and the mechanism might benefit from some lubrication.

What he said.
And to add to it you need to make sure the parts you get will all work together and with your frame. Unless you are pretty good at wrenching on your own stuff and just want a fun project, I wouldn't bother.

Another option may be hydraulic rim brakes such a Magura.

+1

New pads and proper adjustment would probably be a noticeable improvement. I doubt changing to disc brakes is feasible.

Thanks

Thanks all. Convinced me not to bother, to be honest - and Iím not very surprised.

I noticed a nick in the frame paintwork today so am beginning to think I might look at a new bike within a year.
bit disappointed, for example the frame lifetime warranty from Decathlon seems pretty irrelevant marketing buff - but the new bikes will be better and Iíll appreciate one, so something to look forward to, perhaps Christmas present to myself !

mike.

I own 2 bikes with fittings for both brake types
the one with Magura HS 33 hydraulic rim brakes works exceedingly well...
I have little motivation to change them.. But it has the fittings
the other came with disc brakes and covers over the un-used V brake posts ...


No Halfords over here..

This is a good option and a way to get the benefits of modern disc brakes on older bikes with rim brakes. The technology still works but now you can get the added stopping power of hydraulic brakes.

Least expensive way to upgrade the brakes on your existing bike.

if your heart though is set on disc brakes, like other posters have already said, its just easier and cheaper to buy a bike that already has the brakes you want than incur the cost and hassle of installing them on your current bike.

Good luck.

Another approach is rebuilt wheels with drum brakes, also all weather stopping , just not the fling you over the handlebars high power..

And retrofit onto older rim brake bike's frames & forks, unlike Disc Brakes.. I have a set on an old MTB ..

Good call. Really, cable disk brakes are not any better than good rim brakes. Caliper brakes with good pads are very effective.
Hydraulics makes a big difference on either type - but probably not an expense you want on a bike that you are not absolutely in love with.
