Detailed Photos of the Hooker Aero SL Brake Caliper

Google image search has failed me.

Does anyone have photos of the Hooker aero brake caliper?

I would love to be able to get some dimensional measurements as well.

Please post photos or email them to me.

Thanks,

-SD

no one?

Paulo? gregclimbs? AC?

SD

I have one right here on my desk!

PM me with an address and I’ll get some photos to you. And whatever dimensions you want.

email is in my profile and here:

Thanks, I’ll surely have follow up questions but for starters:

off hand, do you know the cable pull requirements? i.e. the amount of cable needed to pull the pads from a reasonable distance away from the rim, to contact to adequate pressure to stop. Do they function better with SLR type leverage or linear?

-SD

i would approximate that ~.5cm cable pull results in ~2cm closure on the pads.

I own two of the Hooker Aero SL brakes. One is on my TT bike, the other is a spare.

Last fall I wind tunnel tested it against Dura Ace.

It was fast.

Now I want a picture of a monkey riding a Lotus or a Hotta!

What is that splitter between the bontrager spacer and the bottom allen bolts on front of the the open face stem?

will this work?

your fork- however, does not look that fast. did it test more aero than the cervelo model?

I use the Blackwell these days, which is not UCI legal, but is pretty fast.

for the JTek lever

Hah, thank you. That’s two rear stays and a downtube away from being the new Orbea Ordu.

I thought AC previously stated, "· ……….you wouldn’t expect that moving the brake would result in huge gains…heck, even if you leave off both brakes, both derailleurs, their control levers, and the small chainring (i.e., test a track bike) the difference is still rather small.

The difference is small compared to the “big picture”, but still large enough to make a difference. More than just moving the brake however, and not shown in the photo, is that the lack of cable housing makes a difference as well, and the relative lack of housing (on the Hooker) may possibly make it even faster than behind the fork systems. http://tinypic.com/...p?pic=4ucbrp&s=2

i’ll race you on any bike setup, your choice of fork, versus me on the same bike with a reynolds ouzo aero. whoever wins, the difference in the amount of work i do compared to you will be offset by me leaving the powder out of my water bottle and making one extra trip to the porta potty so that i can get really tucked down.

next “that piece of gear looks fast no matter what the engine is” comment gets even more sarcastic commentary :slight_smile:

can you define fast (or faster) in this instance? when it all calculates out, what 40k time difference are we talking…couple seconds at best?

and the relative lack of housing (on the Hooker) may possibly make it even faster than behind the fork systems.


interesting to see this, as i’ve recently decided that i’m going to switch out the oval/tektro front brake and put a hooker brake on the front of my bike for just that reason. i’m just guessing, but it appears that the loop of housing and cable negates any aero saving gained by the brake position. the hooker’s smooth shape and bare cable directly in front of the head tube makes more sense to me. that, plus the hooker’s braking power, although not great, has to be better than the tektro. i long ago replaced the rear tektro simply for safety reasons.

no one?

Sorry, mine disappeared along the way (long story not worth repeating here).

BTW, if you (Felt) are thinking of designing an aero brake that would fit standard equipment, provide reasonable stopping power, and was reasonably light weight (for the weight-weenies out there who foolishly obsess such things), I’d say that there’s a market out there. It is certainly a more appealing approach than proprietary fork/brake systems.

Will the hooker brake really work without some kind of hanger for the casing housing?

The Hooker Stem that I was using had the hanger built into it. The way you show it in your pictures, how does it work?

Thanks

No, you need a cable housing stop somewhere upstream from the brake. They are available for both threaded and unthreaded forks, although you might have to scrounge around a bit to find one to work with a particular setup.
