did someone here put gears on a pompetamine? was it hard?

Easy with hub gears. I fitted a SRAM s7 to a Pompino. Didn't think too much of it so upgraded to an 11 speed Alfine. If that ain't enough range( approx 28-130 gear inches)you could fit the schlumpf mountain drive but I've no experience fitting that so can't comment on how easy that'd be.

They probably waste more than that getting rid of whatever traces of head there are into the drip tray.

Auto vacs sorts that one out. Although we have a beer engine with a sparkler fitted, without auto vacs,and I measured the wastage on the last barrel (72pint) including the sludge at the bottom of the barrel it was 5 pints. So price per pint eventually worked outat £1.20 and Sooo much nicer than bottled beer.

Seams like she's not a very good business woman. A northern pint with 10mm of head is about 40ml short of 568ml. You'd get an extra 5 pints per firkin which in London money is about £20.

+1 but it ain't just London where you don't get a proper head. It's the little plastic sparkler they screw onto the pump that creates it. Next time your up north find a friendly local landlord and ask if they've a spare and take it with you to the pub down south. It's quite amusing watching bar staff struggling to pull a pint when they've fitted it!
Does anyone know where the north/south beer devide begins? I know in Cambridge they serve flat/headless beer and derby its served with a proper head. But there's a lot of milage between that I'm not sure about.

How about one of the oldschool hangers, that were used with centrepull brakes, that attached to either side of the seatpost clamp. You'd have to turn the clamp 180 though.

My sm polo pomp hasn't one either. Why not use v brakes?

Thanks for the techy docs mechanical_vandal. Hopefully with regular oil changes I'll never need them.

The Germans love them so they're really common and cheap to import from germany

^^^ the 8 speed is virtually the same as the nexus and packed with grease. The 11 is oil filled and much much simpler to service yourself.

There's a few YouTube bids showing how to strip and regrease them. Id try that first They're supposed to be serviced regulary. It's recommended you do an oil change at 6 months with the 11 speed then annually. Not to sure what's recommended with the 8 though.

^^ I bolted mine to the rear of the fork where there's a thread provided. It does kick the mudgaurd out a bit so you'll have to trim the stays. For this I used a pair of heavy duty cutters(snap on) borrowed from a mechanic friend. Stainless is a nightmare to cut using a hacksaw unless you have the right blade.
The rear one I fitted without drilling, then removed the wheel to line up where to drill. If you don't have a drill you'd probably get away with heating a nail or screw up on the gas and melting a hole through.
It was definatley worth the hassle. Mudgaurds are a must in the uk for at least 6 months a year. I fitted mine last winter and haven't taken them off since

What temps are the cool balls good at? Are they the same as the one landslide got from you that we've been using in Sheffield?

^^^^ must have dropped something really heavy on it. I use sputniks On my polo pomp and someone stood on one last week in a pile up. It only put it a couple of mm out of true. I thought it'd look like a pringle. They really are bombproof.

^^ not sure what's going on. It only really happened when it was new. Also the weather was very cold when i put it together. It seamed to improve as the weather warmed up. I've since given the hub an oil change and it hasn't happened yet this winter. I put it down to a running in period. As for cable adjustment I fitted a barrel adjuster at the hub end to fine tune it easily.

^ I've had this happen too on the 11 versa but the other way, it'll sometimes jump from 6-10 which is a pain if you're climbing cos 6th is about 55" and 10th is around 115". As you said, once you get the feel for it it's ok and rarely happens any more.
The electronic hub? I've not experienced this yet, I'm always suspicious of replacing control systems that work perfectly well with electric motors, switches etc. The beauty of the bicycle to me, is the ability to fix it yourself without needing a degree in physics!!!

^^ ah misread what you meant there. The problem with other shifters is cable pull. If it ain't spot on you run the risk of trashing your hub. Thre are some gadgets like the problem silvers travel agents on the Market and different gear manufacturers use different amounts of cable pull. If you're lucky enough to have a set of SRAM,shimano & campag 8 speed shifters lying about, you could measure the pull and see if one of the pull adjuster thingys corrects it to match the alfine the Alfine.
Lemonade there are still no drop bar Alfine comparable levers that work with v brakes. Again the travel agent is the only bodge I know of, but cycle cross disc callipers do work with them.

^ yep they do an 11 speed versa shifter I'm using that set up. The pull on them is the same as cantis/road callipers. The disc callipers are road rather than mtb so it works fine. They're indexed and the shifting works opposite to each other (little lever drops from 11-1 on mine) default is top with no cable attatched,so fingers crossed the cable don't ever snap or i'll be pushing home! Defo not interchangeable. Also bloody expensive (£160) but that's what you'd expect to pay for the same sort of thing for any derailier lever/shifter set up.

I'm thinking about getting a pompetamine, how much roughly do you think I can get for a secondhand pompino?

That'll depend on the build and condition. A Standard on one will be less than one with nice components. I payed £250 for mine which was pretty much standard in good nick off eBay. Got a second hand frame and forks, from a friend, for £65, that I've built for polo.
If youve nice bits already, You could buy a pompetamine frame,an Alfine hub, spokes and a rear disk brake and use the rest of your stuff then sell your old frame. Or cold set your frame to 135 and get the Alfine hub. They're quite cheap if you get it from Germany, they seam to like them there.

I emailed Harvey about winter balls. He's out of stock and not getting more due to the lack of demand and the number of balls ^he needs to order makes it unviable. He suggested franklins yellows which from the small amount of googling I've done are £20 each Inc shipping.

Too right. I'll need to checki can get home after though.

^weakest part of the drivetrain I've found is the right side of the crankset. Thought I'd hit a neutral but the chain weren't movin!!!

^ yeah the pentaclip can be retro fitted. Different density rubber blocks are available. If the hardest still ain't hard enough you can put a wide jubilee clip around it to stiffen it up more. I would be inclined to try a crankset from a spares bin before buying anything. I'm not sure if the chainline would be right. 165 cranks might help with pedal strike or maybe spd's.

^ There's 2 options 1: cheap and chearful (with gas tube head) £30 or 2:delux with a proper head £50 from the wording it seams like you get one mallet.

Lancaster United Instuctional: Fixcraft Coupler - YouTube

This is a reasonably good instructional on mallet building. You don't need a fancy fixing system. A m6 nut and 50mm countersunk m6 bolt will do. And use a ruler to get your holes for the shaft central. All the rest is available through magic, lhbpa or throw-in

Last night we were playing in temperatures below zero. Its -2 here tonight and it's likely to get colder. We're gunna need winter balls soon, before we end up splitting all our summer balls.
