KK Rock n Roll - Best Price?

dw300

edit .. Sigma Sport are doing 10% off Accessories, Clothing and Nutrition at the moment using ACN10 at checkout, meaning the KK RnR is £292.49.

Does anyone know of any sales/voucher deals that'll get me a KK Rock n Roll for under £325?

That price is from Sigma Sport. Wouldn't mind some feedback on that retailer if anyone has used them before.

Thanks.

sigma sport are good, i've bought from them online several times, no issues, had to return something due to sizing, went smoothly, also good service in the store

dw300

Thanks for that sungod!

I recently bought a Rock n Roll from Sigmasport.
Quick delivery. Slight issue was that the Quick release skewer was missing. A phone call got it sorted and it arrived the next day. So yes I'd recommend them.

Thanks Charlie.

Have you used the trainer enough to know if it makes long training session more bareable? Im hoping that the movement and ability to get out of the saddle for longer will help bloodflow to the posterior maybe?

I find it a big improvement. Best upgrade that I have made.
It took a little while to get set up correctly though. I also went for the Turntable Riser Ring for the front wheel which definitely adds to the realism.

Excellent, many thanks. Now just need to decide if a PM would benefit me more. If I leave the purchase for a 3-4 months till I'd really need the trainer do you think it's likely to be much more expensive, or is it generally possible to find somewhere doing it around the £325 mark?

Also Charlie ..

The pro flywheel is supposed to have a 60 second spin down time from 25mph. You couldn't give me an idea how long the regualr flywheel is in comparison next time youre on could you?

My no-flywheel fluid trainer is about 5 seconds, so even the regular one should feel more realistic.

Thanks!

One more vote for Sigma. Used them a few times and had no problems.

Used Sigma a lot and had very good service both in the shop and with internet buying.

I have used the 1st generation RnR trainer regularly over past 3 years. No problem with using the trainer for up to 2 hours, the sheer tedium of doing so is a much bigger issue than the backside. I have the bigger pro flywheel and think it is worth the money, however the normal flywheel is also pretty good. You can always run it with the regular flywheel and then buy the pro version later as it fits over the basic flywheel and is very easy to attach. It does take a bit of adjustment to get the tilt setting right, but once set up there is little maintenance.

As others have said the turntable riser ring is worth getting. Currently on my second riser as it does get affected by rust if not cleaned properly/regularly.

No matter how "nice" a turbo is, a power meter would yield better returns if you already have a perfectly functionable turbo and are motivated. If it was one or t'other it would be PM for me every time.

Yup. I'll hopefully be commuting more, and so incresing my overall mileage, and even without that the PM would really help me. Its fun attempting to do benchmarks and fitness testing on the road and with Virtual Power, but a PM would tie eveything together better.

Im thinking of selling both my cranksets, and installing the same BB in both bikes and buying a single Rotor Crankset and rings with P2M PM.

mulletmaster

You know the answer then! Get saving for a PM. I have had a P2M for almost a year and it has been flawless. Bought a Stages for versatility reasons, swapping between TT bike and commuter and it was grand too until it started the battery draining trick hence why I have a brand new sealed one. Realistically two power meters is overkill for my needs and abilities though so selling the new stages and just sticking with the P2M.

25mph was a big ask after that HIIT workout lol

I got 23 seconds. I am hoping to borrow the larger flywheel at the weekend so it will be interesting to compare.

As others have said though, if your budget won't run to both then the power meter will give you more. Outdoor/indoor data with Golden Cheetah is the way to go IMO

Thanks Charlie, 25 secs seems decent for the standard fly.

So do you know anything about Rotor Cranks? .. http://www.bikeradar.com/forums/viewtopic.php?f=40042&t=12975052

No. I went for Stages for the ease of swapping between bikes and the price.

dw300

Went for Stages too. Got a new warranty replacement 105 off a local guy for 520 in the end.

Incidentally .. Sigma Sport are doing 10% off Accessories, Clothing and Nutrition at the moment using ACN10 at checkout, meaning the KK RnR is £292.49.

Good price is that. Just picked up the heavy flywheel so will give it a coast down test later.

Was it close to the 60s? How does it feel?

62 seconds. Feels like an improvement to the realism. Interesting that my mate doesn't like the extra vibration on his road machine but it didn't feel any harsher to me. Maybe the Rock n roll parts are acting as damping?
I was blowing out of my backside too much to give it a proper appraisal though to be fair. I'll give it a go on an easier workout later in the week.

dw300

Sounds like it could be an interesting investment. My RnR should be here in the next couplle of days. Will be good to get a trainer i can move about on and coast to get rid of some of the unrealistic stress on the legs from constant resistance during intervals.

Winter training is going to be a lot more bearable that's for sure.

Ah, now I understand your other post about swapping HT2 cranksets twice a week!

Yup, potentially swapping PM between training bike and racing bike.

Ok, first impressions of the Rock n Roll..

Seems well built.

Unit is smooth at high speeds, but I can feel a little vibration / grinding through the pedals at low power. Might just be the chain if the derailleur isn't set 100% sweet. Can't feel it on the road. Everything seems tight.

Nice mountain stream noise from the resistance unit at low power lol.

Flywheel is a nice improvement from my previous no flywheel trainer. Makes things a little more comfortable.

Not sure about tightness of elastomer stack yet. Legs lift off the ground when leaning aggressively, so too tight maybe? However it feels like I wouldn't want it any looser for small amounts of rocking in the saddle.

QR isn't particularly quick. You still have to screw it to tighten once you have it engaged to hold the bike. I thought it'd be a matter of initial setup, then just clamp in place each time.

Need to make a mark on the resistance unit screw and know to make sure I'm in the right spot each time.

First 20 minute test didn't seem any easier!

Not experienced the legs lifting off the ground? I was out of the saddle for a really ragged minute on Tues and the only problem was my own legs. Maybe I'm not being aggressive enough
Agree about the Quick release though and the fact that it is well built.

I did find it took some time on the initial set up with the bike leaning but once that was sorted then all seems good.

I think I'll slacken the elastomer bolts off a bit and give that a try on my next ride. If the seated rocking feels little different i think that'll solve things.

I greased everything when I built mine. i can imaging the legs might be hard to get off if they rust a bit where they insert into the trainer or the bolts seize. But I like to be over cautious.

I noticed that to centre my bike I actually have the lock nut full wound off (sitting against the adjuster on that side) and then the whole thing screwed as far towards the clamp as itll go.

Im hoping the vibration is something to do with it not sitting quite right on a rough concrete floor. Once i get rid of that i'll be 100% happy.

charlie_potatoes

Mine is on a rug so maybe that is the difference
