On One Pompino owners...

If you want a disc-braked 650b bike. Buy one of those and leave the pomp out of it. FFS!

Have to agree with @dement, my Pomp has been a mountain bike, a touring bike, a commuter, a polo bike and is now a road bike ands done all that without 650 wheels or disc brakes.

Ok, ok it’s probably had a front disc at some point but (IMO) dick breaks + 120mm spacing don’t mix and 135mm spacing + fixed use don’t mix very well or very easily.

I think part of what’s great about the Pomp is that it’s not bang up to date, on trend or whatever. It’s basic, it’s cheap, it’s functional, it’s timeless. Mine’s as useful now as when I bought it probably close to a decade ago.

A cheaper version of the urban racer would be rad though

I agree with @M_V in that my pompino works well with rim brakes and 700c however i note that my Pompetamine with 650b*42 is great fun.

Agreed!

With you on the rear spacing. Suppose I just really want a tapered headtube so you can run modern disk forks, but they are unlikely to do that given they won't spec it with disk forks.

This is more what I was trying to put across- If they did a standard pomp and then something awfully similar to this but a fraction of the price, that'd be ideal

I think it was suggested before but PX current business model is buy (for example) 10,000 Pompino frames at 1 x and sell them at 3 x.

When you start talking about 2 different frames you'll be buying 5,000 Pompinos and 5,000 Other frame and you'll get them for 2x because of the reduced quantities. To make the same profit you can't sell them at 3 x or even 4 x , you have to increase the price to 6 x.

By the way, I know they do a lot more than triple the price they buy them for. I'm sure someone that worked for PX once said it was more in the order of adding an extra zero on the end of the price.

Anyone got a spare medium Pomp floating about the garage? Been on the hunt with no joy-closest alternative I can find is a Mash work which seems too plush...

Trek Crockett

Similar because it has 2 wheels?
Its not even made of the same material

Steamroller?

Edit: actually come to think of it we're all talking about this bike but with bigger clearances.

Did those kaffenbacks with the sliders really have dropouts that changed the spacing down to 120mm?

Pretty special if so.

Also a pricey feature I’d imagine.

Dunno what the last version was priced like but I’m pretty sure I paid £99 for my Pomp which is about what Paragon Machine charge for a set of swappable dropout plates plus 1 set of inserts and they won’t change the spacing.

120 spaced sliders, nope .. but on an economy of scale to the order of 10k+ units I imagine the cost would be pennies to add the option, development costs aside.

Any dropout or track end can exist at any width but I’ve personally never seen a dropout system that can add/remove 15mm of spacing.

I think these things are more Mash Work than On One Pompino.

So your point is that it doesn’t exist or that it can’t exist?

To be frank all it could take is a well engineered spacer kit

That as far as I now it doesn't exist and that for Pomp budget its very unlikely it could be brought to production.

Not with that attitude, no.

Come to think of it, rear end spacing is only half the battle...

With the Day One frame I used to have, in order to run it fixed I had to choose between running a spaced out 'track' wheel with circa 42mm chainline or using a disc rear hub flipped round with a bolt on cog which had a wider chainline.

I don't think I had chainstay clearance to do the former (it'd have also meant finding a longer axle for an unbranded sealed bearing hub, not easy) and the latter gave a rear chainline that was wider than the outer chainring position on the GXP road crank I was using.

I opted for the latter and had to fit washers between my crankarm and chainring to correct the chainline.

Either option was sub par for a bike which was to be set up fixed for the forseeable future, neither would have made for a quickly or easily swappable setup.

The hub I was using was a trials hub so it had a freewheel thread on the other side but the chainline on that was different again. A disc compatible cassette hub could be set up to give the same chainline fixed and free but to go from that to a geared set up would require changing the front chainline.

On the other hand, it'd take around a minute to swap a flip flop fix/free track hub in my Pompino. Had I not cut the brake posts off of mine*, a further minute or two and I could fit/remove the rear brake as appropriate. Infact, I even have a 120mm spaced hub that takes a 5 speed screw on freewheel and a DMR hanger tug should I ever want to run gears on my Pomp.

*I've only cut the post part off, I intend to drill and tap the bases of the brake mounts so I can have removable brake posts on my sub £100 frame.

Same issue with my day one, wanted the option to switch between fixed and free and it was always a pain. Ended up running an SS DMR revolver with a track cog and an old BB lockring or the standard SS wheel. Quickly came to the conclusion that its 135mm with gears or 120mm SS/fixed, any other combo is just too much hassle.

My prediction for the Pompino V5 is 40c tyre clearance and small tweaks to the geo (steeper seat tube and longer top tube), they know their audience and wont make any dramatic changes. Basically a Bombtrack Arise 1 but 120mm spaced and blue.

All the above doesn't seem relevant to the purely hypothetical proposition of On One developing a set of 120mm (stepped in) sliders.

The rest is just frame design.
