Bike polo mechanics & fixing

Has anyone given these a go yet?

I've used a standard BMX one in conjunction with one of these

to lengthen the cable to the rear and it was peachy, used a proper V-brake lever and it all felt great. Cost me about £12 in total too.

Only changed as i switched back to disc brakes and the cable wouldn't reach down to the caliper.

Why won't it work with short pull?

(I'm long pull on my polo bike, just wondering why?)

they also have a shortpull version

Garth from Seattle, who makes L'Esparance frames, has made a "hydro proportioning valve" so that you can run two hydro disk brakes off one lever, and one of them will kick in before the other: http://www.flickr.com/photos/garthnet/8362391074/in/photostream

Sounds rad

Jimbilly was telling me there's some kind of workaround to make that happen without any mods...

Would have been better to have a proper bias valve. Easy enough to copy the design from high performance cars.

Also he doesn't seem to have addressed the issue of running two brakes off one lever - twice as much fluid needed to move therefore twice as much lever travel.

Not trying to shit on his parade but it's flawed. I'd have done a dual hydro system a couple of years back if making it work properly was as easy as that.

We just played polo in the rain and my road caliper brake worked better than a paul motolite. #youcantexplainthat #newtrend

Motolites have more parts which can be adjusted so they're harder to set up than caliper brakes.

I've just swapped my Avid Juicy 3 and 180mm G2 Cleansweep rotor for an XTR M975 with a 160mm XT RT76 rotor.

One man's folly does not make a trend.

Also jagwire is awesome. If you're running disc I'd recommend it over Nokon.
Also it's best to have no breaks in the housing if possible so might need to reconsider oilers if you have those.

This is breaking news. I thought nokon and oilers where the dogs?

In other news, this is pretty interesting if you've got a raw frame.

Favour time again.

Does anyone have the tools to replace hope pro II bearings? And if you do could I borrow them? Many thanks.

Ha, I need to replace my bearings too.

Those splitters are a piece of piss to make. There's loads of info on making them from old crank arms. In the trials world they're generally used to clean up the cable routing to magura rim brakes.

I was speaking to some of the pedicab people and they were saying that they've successfully built dual hydro's using Giant MPH levers. They said that the MPH brakes push more fluid than anything else. I think it was old hope or old hayes calipers that they'd hooked them up to.

I have an old mph system sat in a box. I've also just replaced my Deore system. I feel some measuring coming on.

Ideally you need a larger piston at the lever end - modified moto trials lever? And a pair of calipers possibly with a smaller piston so that you don't have to use such a large piston in the lever. Unequal piston sizes would probably be a good idea, or just smaller pads on the rear. A bias valve is easy enough to make with the most basic of tooling.

Most people are using are using just a front brake now, including me. So I can't be bothered really

@ steadycam - all you need is a hammer, a punch and a 25mm'ish socket, not even bike specific tools, it's meccano for adults. Front or rear hub?

The reason I need the tools is because I previously used the method you've just stated!

Where can I find the two outermost bearings for cheap though?

Do you know the bearing codes? They're often on the bearing or the code can be found online. Many bearings are standard cartridges but some are specifically made for that product.

Ebay has a wide selection of cheap /good bearings. Your local bearing shop may have better quality though

exactly what O'Shane is saying, the front hub consists of 2 bearings 6804 2RS, and the rear is 2 x 6802 2RS, 2 x 6903 2RS and 1x 6902 2RS, the RS means rubber seal.

Good initials.

and if your polo bike deserves a treat get some Enduro Bearings, they are silky smooth and hard wearing. I run them on my DH bike and have even re-used a set in my pro 2 on the polo bike as hand me downs, expensive but value in the long run.

how many rubber seals do you see walking the streets of Moss Side??
