On One Pompetamine

[razorfish]

I too am waiting for a Pompetamine Versa. Been more than a month now since placing the order. Is this normal for On One?

I have an SA 3 speed, SRAM 9 speed and triple derailler, Tiagra level. There's a difference across the bikes but bike weight, tyre choice and presence of mudguards must be a fair amount as well. If we're talking Sportive type distances, up to about 60 miles. Then my limited self experimentation would tell me that my 9 speed hub gear would be about 2mph slower than my triple derailler, 16 v 18mph. So about 25 minutes difference over a 60 mile route. But I can't think of any way of calculating what proportion of that can be attributed to various differences between the bikes. The hub gear is 12lbs heavier, has full mudguards and larger, puncture resistant, tyres.

You don't need to, surely!

I was third on the list and mine arrives tomorrow. They had a couple of backlogs, getting the wheels built and then getting some special cables for the breaks but they seem to be rolling out the door now.

As for why they're not on more sportive style bikes, there'll be a variety of reasons, weight, cost and chain tension being biggies.

The big thing is the lack of advantage, It's not enough to make a hub gear as good as the system it's competing against, it has to be better.


I have a Rohloff and an Alfine, on bikes where I can see the advantages, tourer and commuter, I'd list them but it's ground well covered.

I also have a toy titanium sportive bike   There is no issue with a derailleur that I can see a hub gear improving.

Yeah, but if you're riding a Sportive or any fast group ride and you can't match the pace of the peloton, you may as well be going backwards.

Yup . Just can't find anywhere that sells them. There are different finish patterns too.
Someone had them on their bike on one of the East Coast CC rides which was first time I'd seen them.
I am a bit of a tart when it comes to the bike though.

edit: Oooh, oooh. I just found these

think that would have been me on the east coast cc ride. i got my hammered honjos from planet x. have also recently bought some stainless steal giles berthoud ones from dot bike. two other places i've seen nice muds are practical cycles and freshtripe bikes (both great sites for odd bits and top service) also woody's fenders for quite the best looking muds made of hardwood, they're on my list ;-)

 

[Piemaster]

Hi Velocidad - yup it was you. There are some really nice guards on the freshtripe site. I never intended to fit anny to my Pompino but having seen those........oooh its tempting.

Like I say I make no claims and am unlikely to be on sportives, or fast group rides, so it's really a moot point for me in that respect.

I think my naturally cynical bias comes to the fore here, not only do I look at the generally perceived pros and cons but also the business aspect. The market in consumables, chains, cassettes, chainrings, deraillers and fancy lubes is enormous.

But I wouldn't be surprised to see, maybe just as a concept bike, a sporty, hub gear, belt driven piece of carbon loveliness. It may just be that carbon belt drives are the impetus required, weight can be saved but they won't work with deraillers. Though they do require a split in the frame so that could be a show stopper.

Need to, no, unable to stop myself tinkering with formula, yes...chance of success....zero

Think you need locking in a room with Jimbo for a day,might just cure you

If they build it I'd buy it...if it had a Rohloff. And brazeons. For a rack. And clearances for CX. Yeah.

On the other hand I do wonder who on earth the Cannondale Bad Boy Ultra Rohloff is aimed at. It's nearly £3k!

Hey, I enjoy his posts but that could be going too far.

Anyway minor update on Pompetamine build, I now have the awaited bars, stem, levers, crosstops and Goodridge cable, plus a 6 bolt to centre lock converter for the new dyno hub.

Have had to go elsewhere for the dynohub wheel, can't afford the intended SON Delux yet so have ordered the alfine one via cyclesports, got 10% off as well, £98 seemed quite reasonable for this sort of wheel. As soon as that arrives the bike can be finalised.

The next stage will be a second wheelset with the Alfine 11 & SON Delux, all in black, and a new all black chainset, should come it at around £1k. Then the Alfine dynamo wheel will move to the Surly and I'll decide on whether to put the 9 speed hub gear back on the Surly or leave it as is with the 3 speed and sell the 9 speed. I could even put the Dawes back together as a 9 pseed and go back to selling it complete.

mine has arrived! Will ride it home this eve. The paint finish on it is really good, maybe because it's new but it's very shiney, aside from that I can't say much. It's very pretty in the flesh though. On One use a firm called DPD to deliver it, got a text with an estimated time of 13:36 - 14-36, it arrived at 13:41. I half expected to still be at work come 8pm waiting for it, so credit to the delivery firm.

5 minutes late - I'd have been furious!

11 mile commute home. Having not ridden on drops for around 15 years, I felt really stretched out but was used to it by the end of the ride. It feels more stable than my Bianchi and is less prone to want to change direction when hitting sharp bumps. This may be because my weight is further forward due to the drops. The Alfine is really smooth. Putting power down isn't a problem, it seemed perfectly responsive and there were no issues changing gear whilst hammering along. Don't think I hit the top or bottom gears but didn't expect to. It's very quiet, they should do an all matt black stealth version. The only thing I need to sort out is the break tension. It's fine in the drops but struggling to break really hard from the drops, might be my small hands. In the drops the breaking is immense. It's the first time I've used disc brakes but it's a number of steps up from my rim brakes. I've got slightly larger tyres on the Pomp but they are grooved rather than slick (Conti top Contact) can't really tell whether there is more or less grip than the Gatorskins on my Biacnhi. Eitherway stopping is a lot more controlled and feels like it has more bite.

rack to go on and then probably will take it to the Exmoor Beast to really put it through it's paces. Can't work out how I'm going to get the mudguards on though as the discs are very close the the mudguard mounts.

Seriously envious now, marcw! Mine is apparently due to be built tomorrow, so I guess I might get it by the end of the week. Which pedals do you have on yours?
