Bike polo mechanics & fixing

I ride a coaster on my bmx, would be terrible for polo, they have an adjustable point of engagement, and to be able to actually go backwards without killing yourself it's got to be pretty big (mines 3rd of a pedal), if it's too small it bites all the time and any crank movement throws you off.

I wont comment on hydraulics but I think Eddy, Philip shadowman and Emyr uses them. Can't really recall any other names ATM. Eddy is running SRAM/AVID XO with internal routed hose, Philip I think is running Saints again with internal routing and Emyr is running XTR with external routing.

Chan?

I have the M975, ChainReactionCycles had front/left setups on sale.

Kropa uses one, and Chan did buy an XTR system like mine but didn't stick with it.

Chan changes setups like normal people take dumps though.

No, most people know when they've finished having a dump.

You can still get still get the M975 XTR front for 89 quid with free shipping from http://www.acycles.co.uk/shimano-xtr-m975-front-hydraulic-brake-pm-6802.html?utm_source=google_produit_cpc&gclid=CP2MrOy5qroCFY7LtAodRWgAFw

Or if you know what you are doing, you can buy the parts separately - the lever (30 quid) from CRC, the caliper (39 quid) from fatbirds and some braided cables (you will need 104 as per post below) e.g. Goodridge (28 quid) from Winstanleys.

and some braided cables e.g. Goodridge (31quid) from CRC.

Wrong kit

**Please Note: Goodridge hose kit 107 is NOT compatible with the following Shimano models;
• XTR M975

You want the 104 kit for M975, different fitting sizes.

I use a deore hydraulic, it's sweet as fuck, little lever is perfect for 1 finger braking and the servowave lever means the pads sit a little further from the disc which is nice when polo discs get bent so easily. They are about £40 from rose bikes with the option of a left hand lever as forruns are funny and use the wrong hands to brake. They apparently have the same power as SLX and XT but have Allen keys for adjustment instead of knobs, which is probably a bonus polowise. I'm thinking of putting them on my mtb instead of the hopes I have as they're that good.

Well done on your monthly funny.

Anyone tried these yet?

Low profile, both pads are actuated (a first for mechanical disc brakes I think). Pricey though.

Seb has them on his cross bike

Not yet but have them on order and will get them on the bike once I get the forks sorted. Not too pricey considering a pair of BB7 is abut 55 posted and these are 64 posted.

Very tempted to try the HY/RD one as per below! Now that's PRICEY!

This is a bit of uncharted waters but I am going to give the TRP Spyre Disc a try. It is more compact than the BB7, less fiddly and generally looks better made. Lots of good reviews at the bottom of the page but alas nothing in relation to polo of course. They are short pull which means that paired with a conventional v brake lever will give you a sharper stop but I will counter that with a adjustable lever (I chose the DX, the Avid SD is another option) to enable me to choose my preferred settings. Nice price too at 64 quid for front and rear.

There is also another TRP disc that I am keeping an eye on, the HY/RD which at 100 quid for front or rear isn't really cheap. The reservoir is at the caliper (gulps...) and there is no hose but instead it is actuated by a cable (yay!). Quite a few nifty features too like self centering pads and a lock-out option when you are adjusting them. Again untested for polo but I would love to give one a try when I have the cash.

Those TRP Spyres look the business!

Not keen on teh short pull though

I am splitting the set I ordered with Pique and you can try it on his bike as he will have it installed before me while I am still waiting for the Velvet forks to be available. The dual actuated pads is what I want from them, the short pull is not an issue. Quite a few players are running mini vs with regular v brake levers with no problems.

Gusset chute (non hydro) did the double pad movement shit first, non?

Maybe, were they any good?

I think they were meant to be good but not as good as bb7.

So i've got some new cranks designed for an 83mm BB but my frame has a 73mm. I assume a few BB spacers will solve this?

Raceface do a conversion kit, it'll affect your chainline though.

And your Q Factor.

Send them back and get the right ones, pedal strike, joint issues etc etc.

Has anyone tried running a Truvativ crankset with a MRP Bling Ring?

Similar to the Middleburn Uno (but cheaper and presumably heavier)

Pretty sure there are others but I was looking at 2 particular ones, both US based. Home Brewed Components caters to a larger variety of cranks (including Shimano LX and upwards) but they are currently not taking orders as they are still clearing their backlog. Wolf Tooth is the other. Both are in the region of Middleburn pricing.

I thought you said you are not going to get bling cranks?

I'm not spending Middleburn money but I thought (haven't checked yet) I'd probably be able to pick up some cheap Truvativ cranks on eBay.

I'm trying not to be spendy but it's so easy to get sucked in. eBay prices are looking like I need to spend at least £50 for external bb cranks.

Just a note about chainrings, raceface now produce a 30t ring for 104bcd cranks.

IME You'll be waiting until the end of time for a Home Brewed chainring, they don't even bother replying to emails... Looks like a very disorganised one man operation, it's a shame cuz the product looks great...
