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

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 ;-)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![]()

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 bikeThere 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.
You don't need to, surely!![]()
Need to, no, unable to stop myself tinkering with formula, yes...chance of success....zero![]()
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.
Think you need locking in a room with Jimbo for a day,might just cure you![]()
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.
