Bike fit / correct riding position

  • Sensible.

    Saddle and its position relative to bb are the key things. Then jistget handlebars in a good place.

    But saddle needs to be different hight if shoes different.

  • Bad ankle pain (inside directly on the bone and above). Was symmetrical, but has healed quicker one side than the other leaving me sore.

    This is after the 100 miles last week. I thought it was an overdoing-it injury, but week later it's still creaking as I move.

    Any clues what to change? It was a long, long ride but not had the issue before with any of my bikes. I have little or no float in the shimano cleats, but as said, wasn't a problem before on 90 miles up hills and stuff, and never a problem on 30-50 mile rides with the setup unchanged.

    As far as I can see, my feet remain quite level, I don't point toes down much or at all, and the cleat is back as far as possible to avoid this anyway. Maybe angle?

  • Any clues what to change?

    chop it off above the ankle, and direct mount the cleat to the stump.

  • WTB:
    Need one 190 nds crank

  • Finally a sensible suggestion.

  • I've been looking at buying my first road bike and am fairly settled on Decathlon's Triban 520, as that offers decent value for money. I've tried out both the medium and large frame. I'm 5'11". The frame sizes are:
    M (55): 5'7" - 6'.
    L (58): 5'11" - 6'1".
    Both these frames felt OK to ride, and I found it difficult to choose between the two. I was testing these mainly riding on the hoods, and I didn't feel as in control (e.g. shoulder checking, signalling) as I do on my normal flat bar bikes. I also suffered from upper arm/shoulder ache after about 5 minutes - although as I was switching between the frame sizes it is difficult to attribute this to a particular size.

    So, advice I'd like advice from you lovely people:

    • Do people take a while to get used to the change in position, or should it feel natural straight away?
    • Would the medium frame offer better control of the bike?
    • I think shoulder ache may be due to how low the bars are, and I guess raising the bars could stop this. Thoughts?

    For context, I usually commute around 100miles/week on flat bar bikes with out any aches or pains. Probably looking to use the Triban for longer weekend rides rather than commuting.

  • Yes, drops will take some getting used to.

    Compared to the medium, you'd be more stretched-out on a large which won't help.

    Compared to straight bars, you'll be putting more weight on your shoulders: you'll get used to it.

    NB I am not an expert and am often wrong...

  • A smaller bike can be made to fit a larger person a lot easier than the other way round.

  • This is what I want to hear. I am OK with fiddling around with stem length/spacers for a while to figure it out until it gets comfortable.

    Going off topic, I've just noticed that Chain Reaction have a Vitus Razor for £390, which seems to be comparable spec to the Triban 520 so I'll be musing over the merits of those this afternoon.

  • Frame look pretty similar, the women version quite likely to have a slightly taller headtube than the similar sized Triban.

    Look like it have similar amount of clearance for large tyres too.

  • The Cube Peleton is a very very good bike for the money (slightly cheaper than the Vitus) and the geometry have the headtube length of a 56cm bike but the reach of a 54cm (the 53cm model).

    No mudguard mount thought.

  • Thanks. Taller headtube means it'll be less likely to make my arms ache right?

  • Kinda, the reach will feel slightly shorter than the B-twin you test ride because of the unusually taller headtube.

    The bike should feel like it fit like a glove, you're fairly tall but the 56cm from your description felt like a stretch, so the 54cm with spacers/or the Cube Peleton in 53cm will be enough for you.

  • Had seen the Cube Peloton, but initially discounted it because Claris, not Sora. Would this make a discernible difference? Google has mixed views on this.

    Thanks for the sizing advice, I'm gonna measure me, my inside leg, and compare sizing with current frames when I get home later.

    Vitus Razor VR Womens and Vitus Razor VR seem to have exactly the same frame geometry, according to the size guide. What's the diff?

  • Difference between Claris and Sora is pretty small, they both felt the same (shifting and braking wise), just the latter is cheaper and last longer than Sora.

    Found geometry chart for the Vitus, no difference between male and female model, just the paintjob.

    Also geometry chart show that the 54cm also have a large headtube (similar to a 56cm).

    TL:DR; any of the bike you'll choose you'll be happy with.

  • TL:DR; any of the bike you'll choose you'll be happy with.

    For sure.

    And if not I can always sell it.

    Looks like I'll go with the Vitus in 54cm.

  • Your saddle looks too high.

  • Looking at the video again, it look a gnat too high.

  • I'd say definitely too high. Pedalling under load on a turbo trainer will paint the picture, compared to the video posted.

  • I assumed your defintion of too high would be something like 5cm?

  • :-D I don't think quite that much!

  • Saddle is at the same height. 100% sure. First week after bikefit I had to go again because knee pain and was because seatpost slipped 1cm. There's a sticker now on the seatpost.


    I can't really tell if my knee angle is different, photo, angle of photo etc.

  • You knee angle looks different to me. But more importantly, so does the angle of your foot at the bottom of the stroke.

  • Looking at a Genesis Vagabond, geo is here

    My Soma ES (56cm) is properly fitted to me for road cycling, I'm stretched out, but have a little bend in my elbows. the frame reach is 395mm. The large Vagabond is exactly the same, even though the effective top tube is 25mm longer. I will defo test ride before I buy, but should I be aiming for that size? The Vagabond also has about 45mm more stack, so I'm thinking it'll equate to the same amount of stretch, just slightly more upright, which would be decent for commuting and touring and light offroad, which this will mostly be for. My ES isn't an overly aggressive position either, and I use a 100mm +10 degree stem.

    Any thoughts?
