View Full Version : Where's his disc?

Probably obvious, but my mate spotted this bike with no disc and some other sort of braking system around the circumference of the wheel today. He snapped a piccy on his camera phone (poor quality):

Can anyone shed any light on what this system is, please?

The disc is on the inside of the rim.
It's like the Buell system.
Instead of having a small disc around the axle, its a big disc on the rim circumference.

Thanks for the quick reply. Any name for this braking system so I can google it?
Rim discs....Drools...vey expensive as you have to buy a special wheel, then the caplipers, then...oh the list goes on. If IIRC, its somewhere in the region of £1500-£1600 :shock:

Nothing special about that mate,he has nicked the brake blocks off his Raleigh! :lol: 8)

It looks like he has had problems balancing it, there seems to be a lot of weights on the rim

Yeah, I thought they were V-brakes form an Apollo Extreme or sommink! lol

what looks like weights on the rim is actually where the rim is attached to the disc
demon tweeks do them

Doh! Im off to specsavers then :D
Rim brakes, very trick, very, very expensive. I think AP Racing do them.

Why would a racing company do them? :?

my old pushbike had brakes like that :lol:
my newer 'posh' mountain bike has hydraulic disc brakes like on the SV.
The fluid reservoirs are the size of a large postage stamp

Because not everything with the word "Racing" in the title is for the track alone... Do you not have R&G Racing bungs? :) AP are one of the big names for brakes.

Must be a new bread of termites :twisted:
Question: Why would you pay out £1,600 for rim brakes on a Gixxer :?: Possibly to make it look more like a Buell :?: :lol:

I quite like the City X BTW :oops:
They aren't any better than 'standard' disks, otherwise wouldn't all the MotoGP, WSB, BSB teams be running them :?: :? :-k
Just a thought... Excuse my ramblings :roll: :oops:

I have seen race bikes with crash bungs though :wink:

yeah only on privately owned bikes with no other funding.
motogp/bsb/wsb dont but thats cos they dont need to reduce the damage they have lots of money, & it's safer for riders that the bike just go sliding that way they can judge where it will end up.
explanation= a bike without crash bobbins is like a football.
= a bike with crash bobbins is like a rugby ball.

Complete and utter rubbish, plenty of WSB and BSB front runners use crash bungs / protectors of some form or other.
Can't comment on MotoGP, they probably don't.

Take one for a test ride, I did, and it was an absolute hoot, made my SV feel soooo slow when riding away from the showroom. Shame I couldn't afford one at the time, can't now either. :(

I bet its really flickable too isn't it (being so short & all that?)

I believe these are called perimeter brakes!?
I read an article in a magazine about a hybrid busa using them (it was 400 bhp) and apparantly they do provided marginally better stopping power with the following benefits:
1: more surface area equals cooler brakes
2: less unsprung weight as no carrier is necesary
I belive the reason they arent used in WSB etc is they only have an advantage when extended braking times are used, perhaps slowing down after drag runs at stupidly high speeds??
I may be wrong tho
They can also cause a gyroscopic effect which makes them harder to change direction as quick as conventional brake equipped bikes.
I think that radial brakes moved the goal posts so that perimeter or rim brakes aren't as beneficial.
They can also cause a gyroscopic effect which makes them harder to change direction as quick as conventional brake equipped bikes
This is true, and perhaps also why they are good on a drag bike? keeps straight line stability
