  • Importance of cadence?
  • Kryton57
    Full Member

    I used to average about 95rpm during road rides. My desire was / is to train sustainable power to help me on longer climbs / XCM.

    This has resulted in training plans recommending 85-90rpm on intervals of 10, 15, 20 mins. This has reduced my average riding cadence towards 90rpm.

    My plans do include intervals (vo2max) at 100rpm plus so the cadence is there, and my sustainable power and endurance is increasing so all good, but should I be concerned my natural cadence is dropping?

    Is it dropping? It’s gone from 95 to “towards 90” so a 2-3rpm drop – hardly wild

    All the stuff I’ve read is that cadence is pretty much a personal thing and you tend to ride naturally at your optimum cadence.

    For long road climbs, cat4 or worse, it pays to use a gear you can spin at ~90+rpm, as it reduces metabolite buildup in your legs while climbing for ~5+ minutes which would otherwise risk you having to jump off the bike or catch up with you after the summit.

    Generally, I’m spinning on the flats too, my average cadence for rides is typically in the 100-110rpm ballpark.

    No one cares what cadence you pedal at.
    No one cares what your Vo2 max is.
    And no one cares what power wattage you put out.
    No one except yourself.
    You’re a mid pack no-hoper.
    You always will be.
    Accept it and move on.

    Cadence helps knees and keeps you on the trails as you age 🙂

    Jeez, there always one arse isnt there.

    Fwiw gwurk i dont give a shit if you or anyone else cares, but id like to ask questions to understand these things with a view to improving my ability.

    Perhaps box your negativity or irritability and focus on doing something helpful for someone, you’ll feel a lot better for it.

    Rorschach answered your question correctly and succinctly.

    There was no negativity or irritability in my reply. Just good truthful advice. I am a realist rather than a fantasist. I apologise if you feel hurt by my words.

    Would you like me to post your paragraph of endeering encouragment in the “sandcastle” thread? Do you think if one if your teenagers your refer to there recieving this text would feel encouraged?

    Luckily im a big boy and can easliy ignore your content which is neither helpful or encouraging in the context of this thread, but I sincerely hope thats not how you communicate to them, else they should quickly seek another mentor.

    Nope. But one word from one person is neither a concensus or necessarily correct, certainly in the remit if a faceless bike forum.

    What sillysilly said. 90 plus keeps knees in better shape as you age. Having had various knee ops and a lot of physio I can attest to this, and it is the common advice of physios who specialise in the area.

    I’m interval Watt training with people much fitter than me and they are on 85 warm up, then doing 100-125, dropping cadence at max resistance on both dials to simulate extreme climbs. The trainer says if I can’t keep up 100-110min I shouldn’t be in the class 🙂

    Think it is down to efficiency / HR zone over power output and how long you can keep this up. They use 20min / 1hr FTP tests to measure performance improvement over time.

    I was on 85-95 starting out. If I ride without a proper warmup I will struggle at higher cadence from the off that they seem to handle with ease. As long as I warm up it’s fine which I guess is why you see turbo trainers at every pro cycle event.

    Transfer this to the off-road and it really does help with the knees, endurance and speed

    While no one outside of my watt group cares about my watts (they go up no matter your age if you train properly with diet), the people I ride MTB with wonder why I was always the slowest, but now close to the top 🙂

    I’ll ask the trainer for a more scientific / accurate answer next week.

    It depends on the individual, some can spin at high cadences, others can’t. You’ll have a natural cadence, ideally this aligns with maximal power output.

    My natural cadence is around 85rpm, if I’ve had a winter on the turbo then I can push it to 90. Today’s ride the average was 69 but there were some very steep (25%) hills where I prefer to stand – in those instances cadence isn’t so important.

    Once you get into the 120+ range then your technique comes into play much more otherwise you’ll be bouncing around on the bike. I can only hold cadences above 125 for a minute or so even after lots of specific turbo training, it’s just not efficient for me.

    I’d like to pick up on the point that someone made ‘natural cadence is generally most optimum’…

    All the literature I’ve read states otherwise and I’ve found so in practice when doing ftp tests etc..

    I’ve got a natural cadence of about 80-85, however I can hold a higher wattage for longer at 95. It feels unnatural but the numbers don’t lie.

    Also gwurk, you’ve spelt your name wrong the ‘T’ is inbetween r and y on the keyboard. Bum wobler!

    Is this any help as a read of potentially more helpful responses?

    Thanks TOJV yes it is, and thats exactly the kind of knowledge I’m after. When performing say 110rpm my legs can hurt quite a lot, but on the other hand, performing 20 mins on the tops at 85rpm feels difficult but not so that I can’t sustain it.

    From your thread:

    It’s a can of worms. HR will always go up for higher cadences as you are using your cardiovascular system more over muscle strength. I’ve heard of pros deliberately reducing their cadence in breaks to lower their heart rate.

    I’ve tried this and it works. You can sit in bunch at say 60rpm in 53/13 and be riding along at 33kmph on the flat with little apparent effort.

    Why is this all like (or worse than) a foreign language to me?

    fifeandy

    No, nothing to be concerned about imo.
    I’m definitely an advocate of spinning as you can ‘replace’ heart rates by shovelling carbs in, but once you’ve used up your muscular strength for the day thats it until you get some protein and a sleep.
    It therefore makes sense to spin a lighter gear faster to preserve the muscles for when you really need max power at the expense of some heart rate.

    If your average dropped below 85 that might be worth spending time thinking about, but 90 is right about what i’d consider normal.

    I went for a flat (for round here) ride yesterday and deliberately kept in a low gear and span. Average cadence was 90rpm compared to Saturday’s 69.

    The rides were somewhat different though: on Saturday I did 109Km with 2080 metres of ascent; Sunday was 47Km with 570 metres of ascent – apart from one climb these were all long gradual affairs.

    The rides shared part of the return so I can compare efforts on some segments. Looking at one (4.9Km, 107m) there’s the following data

    In big ring:
    Time: 12:19
    Avg cadence: 74
    Avg HR: 163

    In small ring:
    Time: 13:21
    Avg cadence: 92
    Avg HR: 148

    My PR for this segment is 11:09 with avg cadence of 82, avg HR 154, this was four years ago.

    If you can be bothered you ought to look at your cadence data via Quadrant Analysis in WK04 or Golden Cheetah. It’s beyond my level of interest

    You have powermeter and Joe F’s book? I think he talks about it there.

    Cadence in isolation tells you nothing. Absolutely no point getting hung up on it. Although I would add that it is good to train across a wide range of cadence so you are happy no matter where you find yourself.

    Krypton Kryton – no idea.. All i know in Whistler when I was trying to keep up with someone where roots were the size of tree trunks he kept saying it’s all about the cadence!!! At which point I just wanted a beer to forget my misery.

    Because there’s sod all resistance from the rollers and he’ll be in a low gear. Bloody good pedalling technique to do that though!

    I find anything over 95rpm hard.. I can hang out in the high cadence club for a club run easy enough because most are spinning it out, but I ride alone most of the time and it drops to 85 which is where I’m most comfortable. But I think there’s a bit more to this than just stats. Riding hills and stuff (say Sth Downs) means you can normally just power on up in the big ring churning it out, look at the stats and mine will be often in the 70rpm range, but I have tried to high up my cadence (spent a year re-training for just that) but it proved pointless, I produce my best power in the 70-85rpm range.
    I’m just a rouleur at heart though, mate of mine is a racer and his cadence is up around the 100 range, and he looks like he’s constantly fighting the bike. Out of about 40 guys I ride with, most are in the 70-85rpm range and honestly DGAS about it, or what science lies behind the urban myth that high cadence = good cadence.
    One mate is doing LEL now, bet his stats come back at 80rpm aves.

    Huh? Surely you can do this in any gear. I’d probably be almost freewheeling at such low speeds in a bunch.

    The problem with being at low RPM in a bunch is you’ll have no ability to respond to sudden changes of pace or gradient.

    If your power is constant then you are putting down a bigger force – that could be down to training. But cadence is largely personal. I’m a spinner#, I’d only be concerned if my cadence was dropping on my fixed wheel road bike!

    #Average cadence for 100 miles yesterday was 98 RPM for 4 hrs.

    At lower power outputs, you don’t need to spin, higher power outputs you do.

    So if you’re doing more intervally training (with lower average wattage) you’d expect to spin slower.

    Spin at whatever speed feels natural anyway, there’s nothing worse than people going along at 120rpm at 10mph on the flat cos they’ve seen the pros spinning and think it must make them faster. Higher RPM will put less load on the knees though, to a point, so try not to strain too much.

    Well. For instance i was targeted to do a 4h 200w average ride yesterday. I returned wih an average cadence of 88.

    Before this year and my recent bout of training, my average has been 95.

    Developing a smooth cadence engages more muscles, so you’ll fatigue less as each muscle is worked slightly less – 90-100 is about optimum. Because track cyclists have a fixed gear, then high-cadence is the way to achieve acceleration / finishing sprint.
    I once did nearly 70km in an hour on a spin-bike as part of a charity challenge – average cadence was 150rpm – didn’t half have a few painful skin rubs afterwards. I used to ride a fixed gear when out with a fast road group – scared the bejesus out of some doing 180rpm downhill
