Hey, ich wollte mir ein Rennrad kaufen, bin jedoch immer wieder am überlegen, was besser von beiden ist.
Vielleicht fährt ja hier jemand Rennrad und kann mir sagen, ob ich mir lieber eins mit Felgenbremse oder mit Scheibenbremse holen soll.

Loading...Ich hab mir schon immer gedacht, da ich kein Auto habe, meine Familie im Ausland mit dem 45km/h Ebike zu fahren. Hinterradantrieb, deswegen braucht man nur leicht zu treten ohne widerstand. Abends im Ibis Hotel alle Akkus laden und früh geht’s weiter. Akkus müssten 4 ausreichen. Zur Not 5 Akkus, die ich in der Seitentasche…

Hey ich suche ein MTb zum Downhillen aber kenne mich mit marken nicht gut aus. Was sind gute Marken die auch Stabil und gut sind? Freundliche Grüsse
Hab auf mein Mountainbike Reifen in der Größe 26×2,25 drauf. Jetzt sollen Trekking Reifen drauf. Die Trekking Reifen gibt es in 26×2,15 oder 26×2,35. Soll ich die schmaleren nehmen oder die breiteren?
Hallo, habe die Kettenschaltung vom Fahrrad eingestellt. Zuerst die Endanschläge und dann die Zugspannung. Nachdem ich die Zugspannung nach und nach erhöht habe, damit man ausreichend gut auf größere Ritzel schalten kann, haben sich die Endanscnschläge etwas verstellt (H- und L-Schraube). Soll ich die jetzt wieder anpassen oder lässt man es jetzt einfach so? Wollte…
nimmt man durch Fahrrad fahren durch lange Strecken ab? Also am Bauch oder an Kilos die man hat? hoffe auf ein paar hilfreiche Antworten LG
Per wheel brake.
Over the past 30 years I drove 4000 to 8000 km a year.
Both on the racing bike with wheel brakes and on the MTB with V-Brakes, in winter inevitably also wet.
Your own experience:
Many, at speeds far over 80 km/h, I had with both wheels never Brake problems.
My current racing bike has been conscious No My wish MTB was unfortunately only available with disc brakes.
The additional weight (1 to 1.5 kg) of a windshield brake system does not have to hurt anyone, especially since it becomes more expensive.
@ Silas79,
Thanks for star ⭐
I wish you a happy choice with your new race bike.
Hello,
Disc brakes are, of course, a fine one, especially for wet ones. But God knows that rim brakes are not very subordinate, with rim brakes you will be so satisfied.
I always find the discussion about discs/ rim brakes funny… in the time before “disc brake” no one has troubled the rim brake as a weak point 😀
I started cycling prot in the 90s and when I pulled the brake, the rear wheel went exactly as high as with disc brakes. Also rim brakes can be brutally packed and can be metered.
rim brakes must of course be set well, in disc brakes one can ignore “Achter” already, with rim brakes minimally the dispensability suffers under aft, and the lining must fit well with the rims (brake flanks). Weak brakes have been dramatically improved with rim brakes with good and compatible brake rubbers.
But… disc brakes are also not self-propelled, which must also be maintained and maintained, just a little further down;D
Have fun cycling;)
Wheel brakes have a better aerodynamics and the complete brake system is a few grams lighter …
That’s where the benefits stop.
With disc brakes you have more braking force in bad conditions. When you drive carbon rims, this difference becomes much more clear. In the case of hydraulic disk brakes, they can also be metered better.
Disc brakes are also very expensive very quickly, especially if they are to be hydraulic. Not only does the wheel need more expensive brake calipers, but also the STI levers need a hydraulic cylinder and you will find it only at the more expensive high end switching groups and the latest 105s.
Is it possible to implement these in practice? As far as the tire grip on wet asphalt is concerned?
On wet asphalt, I can’t even retrieve all the brakes with MTB tires…
I say it once, with aluminium, a rim brake in the rain “strong enough”. If the tire is blocked, it doesn’t take anymore. Here one has a minimum advantage at most due to the more precise metering capacity via the hydraulics.
However, carbon rims are so slippery when wet that brakes are designed for adventure.
Hydraulic disc brakes are already horny.
But they have two major advantages for racing cyclists: You no longer need much force on the brake lever and the rim does not wear. And well, on long (alpine) downhills you need to worry less about overheating and of course not worry about bursting hoses.
Yes, disc brakes can also be delayed better when wet. However, do your tires have so much grip on wet road that this braking force can also be implemented?
Disc brakes have the following disadvantages:
On a mountain bike, the whole is a no-brainer. One is more common in wet and dirty, does not have the problem with a lack of tire grip and is on departure so much on braking that one produces serious heat and quickly get cramps in the poor with rope hoist brakes. In addition, the aerodynamics is eh wurscht and the extra weight is absolutely worth the benefits.
On the race bike, I have my doubts as to whether you really need disc brakes.
Of course, if you have to have the latest and coolest (apparently not a few racing cyclists), you also need disc brakes.
For everyday use, only if one is not too often in the rain or in the mountains, rim brakes are actually completely sufficient and one should consider whether one wants to accept the disadvantages of disc brakes.
Disc brakes make the wheel more expensive and are unnecessary for the hobby driver. My entry-level racing wheel would have a mechanical 105 equipment with rim brakes, even with aluminium frames still expensive enough.
Yes, I’m driving racing bike and I don’t have any problems with my two-joint (dual pivot) wheel brakes even though these are cheap nonames.
My old bike is a 1986 year of construction. I drove alpine passports. If I hadn’t overtaken all the campers down, I wouldn’t have had any trouble on the rim brake. When they get hot, it’s gonna go down a lot of rubber. Meaning I had to open the brake over and over again and became too fast for motorhome traffic. The disc brakes are quite superior. In racing, it doesn’t matter, there’s a huge box almost after the turn, and you can run between the bends.
The disc brakes are more expensive and heavier.
So you have to take care of yourself.
Since I need a drive after a complicated accident where in the stars, if I can ever go without crutches, my race bike with its 12 kg is heavy enough that it does not matter to the weight of the brake. The wheel I fit and like brought disc brakes with me and I enjoy them very much.
Disc brakes are now state of the art
