Strange Bike

daviesee

Spotted in the company car park this morning.

Cannondale hybrid. Nothing too unusual.
Fixed wheel. Nothing too unusual.
Front disc brakes. Nothing too unusual.
Rear disc brakes. ???????

Why?

I saw the opposite last week on the NKR. Looked like a bog-standard track bike (no rear or front brake) until the guy stopped pedalling and the freewheel kicked in :shock:

I followed him for a bit (too curious just to ride past), and he eventually stopped with his foot on the back wheel, BMX-style...

I missed the 'fixed' bit on first and second read......d'oh!

Was thinking "WTF is he on about?"

daviesee

Maybe it'll be clearer now you've picked it out

I even gave it a sneaky lift at the back up to give it a spin to check it wasn't a free wheel.
Nope. Fixed.

I quite fancy an SS with hydraulic disks - anyone know of any STI / Aero levers for hydraulic brakes?

There aren't any yet, you have to get a cable->hydraulic converter; they're quite pricey though, developed for cross.

I have cable-activated Avid BB7s which aren't bad, and work with Shimano/SRAM (and quite possibly Campag too). The whole setup is noticeably heavier than cantis though...

But are they smooth shifting?

for the same reason, folks have two brakes, on a fixed.

which is even on the rear a good brake is a good idea.

I would have thought that a disc on the front and pedal controlled rear breaking would have sufficed.
Maybe some people prefer belts and braces

Best brakes ever, beats discs hand down!

Shoe makers just need to come up with clipless shoes with a brake compound built into the sole, then I can be a weight weenie and remove my brakes to save myself 300g. :roll: How do I patent this?

Might have been flipping and flopping no?:P

ooooh, what Hub, I am looking to sort this on my cotic but only Surly or Paul make hubs which are very pricy, i've found one screw on adaptor but that just looks dangerous.

Why, one brake is fine if you ride a egg beater gear hoxton fakenger rig, if you have a proper gear on your fixed stopping with just leg power is pretty difficult.

Define a proper gear.

Also, it depends how powerful your legs are.

Most of you're braking force comes from the front brake anyway. If you slam on both brakes in an emergency, the rear will unweight and you have to shift your body to keep the rear down (which you would do anyway to prevent yourself from doing a Superman impression).
As soon as the rear wheel is airbourne, it is doing nothing to stop you, so is redundant.

how? there is a disc there!

may have been a SS and he has gone fixed on it though.

I'm quite fond of having two brakes on my fixie, leg braking at high speed downhill is tricky, I'm trying my best not to let my feet overtake my knees and mangle me !

I have been looking quite seriously at the option of a disc brake on the front...

avid BB7 road. doable now and has been for some time. are there suitable forks yet?

or are you wanting the hydros that should be out soon.

I think with the electronc shifters out now i think you will see a lot of the brake makers doing suitable levers and sets. Formula will be there soon.

Most likely answer I think now you mention it.

That would mean there is no lockring on the sprocket. I suppose if it is a SS conversion and there is no lockring you would need a rear brake because if you leg brake you could loosen the sprocket and unscrew it from the hub.
Have a look for a lockring to confirm.

living dangerously...

do surly do a fixed disc hub?

It's only made an appearance twice in the past 10 months so it could be a while and I have no clue who the owner is. Unfortunately, or I would simply ask.

Mine's a Pompino, so a Pompetamine disc fork would just fit right in -- unfortunately they don't make them in brown so I'd need to get it painted. I'd stick with cable disc for versatility and ease of fixing. I may well still do this before winter, I haven't done it yet as I was trying Koolstops to see if they were all they're cracked up to be. They aren't.

Hub supliers: Yes Surly and Paul.
Disc and Electronic: Colnago C59
Road Disc fork: just out by ENVE, else mainly they're cyclocross forks and a fair few are on the market now
Proper gear: at least 80 GI
Available Hydro Levers: Formula (only on a C59)
Coming soon: Shimano/Sram/TRP

If interested in road discs have a browse of weightweenies and bikerumor

I ride a proper gear (81.9"). Yay!

In all seriousness, I'm thinking about going higher. I can get up Bromley Hill seated yet still get off from the lights pretty sharpish. I'm thinking 52x16 (87") may be too big a jump, but I like the look of the 52T ring so don't want to go to something like 42x13 (86.5").

What, you don't ride that spinny little Vitamin gear that that you were on at the Morpeth that time? That's a crying shame, it was extremely entertaining watching you try and maintain mid 20s at 150rpm

That was a killer! Anyone trying to ride fixed in that gear would have their legs ripped from their torso at anything higher than walking pace.
I do like that bike in a big BMX, chuck it around and not care about it kind of way, but was hardly geared for speed. Since that comical ride, I've fitted a smaller freewheel as the original one wore out quicker than a piece of cheese shoved up against a sanding disc, so it's a bit faster now, but hills are surprisingly hard as it weighs more than the hills I tried to ride it up.
