Kurt Kinetic trainers

[snedden9485]

Looking at getting a KK trainer. I have a older road machine on loan at the moment and it feels nice, so i think i will end up getting a KK as i think i may regret it if i skimp on a trainer. Main question is the difference between the road machine and the pro machine. I know the pro has the extra 12pound flywheel, which according to KK's website, is good for tempo efforts and long rides. Is there a noticable improvement in smoothness with heavier flywheel?

I mainly want the trainer to do interval efforts and some sprints ( not too many sprints though, mainly intervals). Will the smaller flywheel be sufficient?

Also, just looking at the flywheel on the one i have ATM, i think making a heavier flywheel wouldnt be a hard task for a fitter machinest. Is there anything different in the road machine that would prevent me building a heavier flywheel and retro fitting it?

16mm bearings on the Pro, 12mm on the Road Machine IIRC.

The Pro not only has a bigger flywheel but at better bike mounting mechanism. This may be of little importance if you look after the threaded rod on the Road Machine.

I think I'd go the Pro if I could do it again, not that I find much to fault on the Road Machine. Alex said something about more road like inertia with the Pro being of some value.

I see. I still think you could make something like a 12 pound freewheel for the road machine that would give it the extra weight for the added interia effect. The pro would be nice, but i dont think i could justify spending the $750 or so. I have seen some good prices on the road machine on ebay from US. Around $299, have emailed re postage, which i would expect to be quite high.

Assuming $50 AUD postage from anywhere, JensenUSA have a Pro which would be about $630 delivered. Is that $299 USD?

[snedden9485]

Nope, postage from Jensen USA is $160 (US i assume)!!!!!

Thats the prob with buying these things from the states, they hammer you with postage! Think il end up buying one locally for the sake of warrantly etc. Sure i may save $80 - $100, but peace of mind is much better.

Ive got the Pro and cant recommend it highly enough.
I must admit I got it by default. Wanted the RR, but they were out of stock. Was offered the pro at half the normal difference so jumped on it and very glad I did so now.

[snedden9485]

Ok thanks Andrew. Have you ridden a road machine for a comparison?

[Rockford]

We should organise a group buy!! I'm looking for a trainer as well.

Admitedly i've only had it for a month, but i seriously love my KK road machine. Not the pro but its beautifully smooth none the less, nice and quiet and easy to setup. Good price to boot. I can't comment on how it compares to the others in its price range as i havn't tried another, but this one does everything i need.

HTH

Yes i got it in this shipment from cycling inform. They were very helpful and it was a simple and smooth transaction.

[ni78ck]

are you putting the cervelo on it?

tried the UK?

[Nobody]

Can't seem to find any online in the UK. Has anyone found one?

[snedden9485]

Generally the spesh, but the velo is in it ATM as my spesh is in the shop. Mounting system is good, so not worried about any issues. Plus the velo is a strong frame

Nope havent found any in UK

Ok thanks Andrew. Have you ridden a road machine for a comparison?

I cant say that I have.

If you guys are looking to do a group buy, contact Ben at Pedals Plus Monavale on (02)99796544
They currently have the RR's on special for $594.15 and Imsure he could do something for you guys with a group buy.

Usual disclaimer, nothing to do with the above business, just a happy customer and prefer to give my hard earned cash to a business that puts back into the sport (Ben sponsors several riders and triathletes)

IS that the price for a road machine?

[Andrew69]

Ha ha.I looked at the site just before I posted and he had the Road Machine at that price.
Just looked again now to post a link and the price has changed back!

Maybe give Ben a call?

Either way shipping is dirt cheap at $9.95 Australia wide.

I ended up picking up a 2nd hand road machine from a mate. Got it at a good price too. Ended up getting the KK riser ring and the KK power computer thrown in with it. Anyone used the KK power meter? SHould be ok to do some basic power training. Im not sure how accurate it is, but i have heard it gives a good reference for training with some numbers.

[Andrew69]

I just set up the KK computer on my wifes bike and the numbers were off by a fair bit (reading high) compared to my PT.
Figured out some new factors for the power equation in the computer and its with 1 or 2 watts of my PT now (up to about twice her FTP)

But that has got me thinking that maybe my PT is reading off, so I am going to go back and do a stomp test on my PT to make sure it is accurate. Would be nice if Im really making 50+ watts more than I think

The only reason I bothered to stuff around with it is that she has done her FTP test using my PT, so this way I can have her work at the correct power levels.

Yeah i wonder what my one is like. I dont care if its not super accurate, im using for more of a reference point for training really.

As long as it is repeatable, I dont think the actual number really matters.

How will i know if my one is out?

So it will calculate power (my KK power meter) regardless of what gear i am in and what speed i am pedalling at?
