Read This Before You Submit !

If you want to get the best possible outcome from posting your position on this /sub, there are a couple of things you can do to help,

  1. Make your video at least 30-40 secs long [ no longer than 60 secs ] This will allow you to settle in to your pedal stroke and give viewers enough time to 'look around' your position.
  2. Post a minimum of 2 angles. #1 Seat height, showing the entire bike and rider from the top of the head to the bottom of the pedal stroke. #2 from the front dead center about head tube height. If you shoot a vertical format on your phone that might help you fit yourself within the frame. #3 from the rear, at seat height, can also be vertical format for cropping.
  3. Post a shot of your bike side on without you on it. This lets people see the 'build' as far as seatpost seatback, seat rail position & headset spacers

The more visual and information you give the better the possibility of good feedback.

Ride on!

Dear mods, save this sub

145 Upvotes

There are a lot of generous and knowledgeable people here giving thoughtful bike-fit advice for free. Their effort is being undermined by a steady stream of unusable videos showing riders leaning against walls, doorframes or furniture while pedalling backwards.

Those clips don’t show a normal pedal stroke, balance, loading, posture or movement under realistic riding conditions. There’s very little anyone can assess from them, yet they keep filling the sub and drawing attention away from posts where useful feedback is actually possible.

The existing submission guidance is already clear about video length, camera angles and showing the whole rider and bike. It should also explicitly require riders to pedal forwards on a trainer or rollers, without supporting themselves against anything.

Please make “no backwards pedalling and no leaning against objects” an actual submission rule, and remove posts that ignore it.

The people giving detailed advice here are what make the sub useful. Their time shouldn’t be choked by videos that make meaningful assessment impossible.

Neck pain after long rides

So- I know this is an Aero bike but still, after more than 80km my neck starts hurting and it stays for days. Normally for longer tours I have my more comfortable gravel bike but am still wondering if there are tweaks to be done to help my neck pain on this bike. I‘d really appreciate some insight :)

I didn’t expect to end in this thread

Guys,

I recently picked up Cervélo Soloist MY27 in size 54 cm and didn’t expect my journey will end before it even started.

I took the size 54 cm because of inseam 84.5 cm and advice from bike shop. I did only a short test ride of previous Soloist model and ordered this one without even looking at Cervélo website. Thought assumed 54 cm is size M as it is in Canyon Aeroroad. Apparently it is not and with my 181 cm their website suggests size 56 cm. Since I only noticed it, this bike feels small for me.

Pedals are not installed yet because either I will try to sell it or returned it (I doubt shop will accept exchange for bigger size). From that reason I can’t also have any outside ride.

Looking for any suggestions how to fix this.

PS from whatever the reason I can’t add video to this post.

Chamois shifts backwards/upwards, sit bone & back pain (197cm / 100kg) – Fit check / Advice needed

Enable HLS to view with audio, or disable this notification

2 Upvotes

Hey everyone,

I’m looking for feedback on my fit. I’m experiencing persistent comfort issues and can’t seem to dial in my setup.

Rider Stats:

Height: 197 cm (6'5")

Weight: 100 kg (220 lbs)

Sit Bone Distance: 14.5 cm

Bike Setup:

Bike: Specialized Roubaix Comp (Frame size 61)

Cockpit: 100mm stem (+6° rise), 30mm spacers

Seatpost: 0mm offset (straight seatpost)

Saddle: Ergon SRS Women m/L (Better Feeling than Allroad Core Comp and Sq Labs 612 active)

Main Issues:

Bib Chamois Displacement: The chamois pad keeps riding up/shifting backwards over the rear of the saddle. This causes me to sit right on the hard edge/seam of the pad instead of the cushioned center, leading to sharp pressure pain under my sit bones (no numbness, just direct bone pressure).

Back & Neck Pain: I get uncomfortable tension/pain in my neck, upper back, lower back, and butt after riding and while riding.

Gear Tried: I’ve tried multiple bib shorts (including Gorewear, Assos, Siroko) up to XXL, but the pad movement and pressure issues remain.

In the attached video, I'm riding at a normal pace on the hoods.

Hey guys, I’m new to biking this season and I’m loving it! I don’t have the budget to get a proper bike fit at this time but I would love some opinions!

Here is my 2021 GT grade expert in size medium. I am approx 5’6-5’7, 162lbs. I know I’m on the lower end of the size range for this frame. I have shortened my stem from 80mm down to 60mm due to feeling like I was reaching too much.

I was thinking of possibly getting a straight carbon seat post rather than the 20mm offset one currently on my bike. My saddle is currently all of the way forward.

I don’t seem to have any glaring issues other than having sitting bone discomfort after approx 40km rides.

Thank you!

New to cycling (indoor trainer)

Hi all,

I'm new to cycling (my only prior experience was with a cheap foldable bike from Amazon where the saddle was too low and caused IT band irritation on both knees). I also have CAM + pincer morphology in both hips (so hip sockets too deep, not enough external rotation) which led me to buy a hybrid bike (Carerra Crossfire 2) for a more upright riding position.

Planning to use this exclusively for indoor training. I am not sure I'll ever get into racing, more likely to use for structured workouts and progressive overload along my other strength and conditioning training, VO2 max intervals/long steady state etc.

I'd be very grateful for some opinions on my bike fit.

I've changed the stem with a riser since the stock one caused me to lean forward on the handlebars too much, was uncomfortable. This feels much better.

I didn't even own good shoes (my trainers kept sliding off the pedals). I've now bought some cycling shoes but don't trust myself to install the cleats and clipless pedals. So far the shoes seem to work well with the stock pedals but did some max effort 15s intervals today and feet came off the pedals.

Currently my knees feel fine, back too, but I've only used the bike 4 times for 1h long rides. The bib makes it a bit more comfortable but still feel the saddle digging in a bit (the spirit level shows it's level, maybe 2 degrees off)

Any feedback greatly appreciated.

Overall fit help!

Hi everyone! I’ve never had a bike fit before but will be in a few months for my birthday.

Hoping you can help give some insight on what you see until then

I do feel knee pain in my right knee, and overall feeling like I have to stretch out a lot on my right hip and right side in general

Hand numbness comes after about an hour in the saddle. Everything else feeling okay but not great. And I also don’t know what I don’t know

Thanks in advance 🙏🏼

EDIT: thank you all so much for the advice and insight! Like I said, I don’t know what I don’t know so this was really helpful. Gonna check everything out and definitely work on flexibility as well.

I have never paid attention to bike fit: any advice?

Hi friends,

First I must say y’all are so hot wtf. Guess I should ride my bike more (good thing that’s the plan lol!)

Now that that has been addressed, any advice for someone who has only ever hopped on a bike without thought to sizing/fit? I was given this bike and I love her so very much and want to make sure I’ll remain comfortable.

I’ll try to add pics in the comments.

Thanks!

Aide pour trouver ma taille de vélo idéal.

1 Upvotes

Bonjour à tous. Actuellement je roule sur un Orbea h40 avant en taille 55. Malgré un changement de potence plus courte 110mm>80 mm, je trouve toujours le vélo trop grand. Une sensation d' étirements constamment présente. Je roule au plus bas des entretoises. Je fais 1.80m et 84 cm d' entrejambes.

Je compte changer de vélo pour la fin d' année et j'ai en vue le supersix evo ( je suis monté dessus en taille 54 et j'étais plutôt bien). Il a aussi le spécialized tarmac sl7 en 105.

Pouvez-vous me dire sur quoi vous roulez avec taille du vélo et du cycliste et comment jugez vous la cohérence de l' ensemble ?

Merci :)

My balls keep disappearing

27 Upvotes

I got a bike fit about a year ago and after following my physio’s advice everything feels locked in. Except for my balls.

Every 5-10km I have to reach down and push my balls out cause they they’ll slowly get sucked up from my ballsack. It’s not painful but eventually leads to numb dick if I dont get em out.

Anyone ever experience this? My bib shorts arent the best quality to be fair. Would this be the likely culprit or is it more likely to be my saddle width? Rocking a Fizik Argo right now.

sizing doubt with fizik vento proxy

1 Upvotes

Hi everyone, I recently got a pair of Fizik Vento Proxy Wide shoes in size 44. Unfortunately, no store near me had them available to try, so I took my measurements and ordered online.

As soon as I put them on, I immediately noticed a huge difference in width (I used a Decathlon model as my first shoe, also a size 44). However, I noticed that from the top of my foot to the bottom of the shoe, there's a thickness of about an inch, almost 2 cm.

By adjusting and tightening the shoe normally, my heel doesn't slip out. The width is comfortable, and my foot doesn't slide forward. Do you think I should go down a size anyway?

I then checked my Decathlon shoes again and noticed that the toe-off is the same, but the sensation is very different because the shoe is much narrower, so I hadn't noticed it before (I tried these in the store, and the smaller size was really too tight).

What do you recommend, based on your experience? They arrived just in time for the bike fitting on Friday. I don't think I can return them and get another pair...

Is this bike too small for me?

Enable HLS to view with audio, or disable this notification

I am not looking for actual bikefit help. Just want to determine if I can ride this bike or should I get a larger size frame. For reference, I am 181cm(5’11) and have a 83cm(32.7in) inseam.

This is a 54 emonda.

I went on a 3h bike ride on it without any adjustments on the bike or the cleats and other than my left foot feeling numb sometimes I had no pain or discomfort but since I am a total noob on this I thought I'd ask. I did feel kinda "crammed" but maybe that is just me not being used to roadbikes. Also, I have a size 46 EU foot and that shit be hitting the wheel all the time, is that normal?

FYI It is not my bike, I just tested it on the weekend.
It felt good, but I got slight neck pain, after a few hours in the saddle. I am around 185 cm tall, the bike was a 2027 Reacto 6000 in Size M.

Thanks for any advice and thougts in advance!

Lower back pain

Enable HLS to view with audio, or disable this notification

12 Upvotes

Hi everyone,

I started cycling back in February and bought this bike in April. I absolutely love the bike, but I’m getting lower back pain on every ride.

As far as I can tell, my position on the bike seems pretty decent, but obviously something might be off. I’m wondering if the reach could be too long, or if it might have more to do with my flexibility, hamstrings, or a lack of core strength (or some other adjustment to the bike).

Would anyone be able to give me some advice on my bike fit or position?

Any feedback would be greatly appreciated!

e-mtb moving bars up and toward me.

0 Upvotes

I want to move my handle bars up and toward me to push me back a little bit and take pressure off of my hands. My current set up is a 50mm stem with 0 rise and handlebars with 30mm rise 5 degree up swing and 7 degree sweep.

do I replace the Stem or the Handlebars?

if I go 60mm stem with 35 degree rise, is that too much? will it goof up my ride?

Hello everyone,

I recently tried using MyVeloFit to get my bike fit where it is now. It still recommends increasing the handlebar reach by 10 mm and lowering the handlebar height by another 10 mm. I am hoping to get insight into any recommendations. Any and all feedback is appreciated!

Hands and shoulders are killing me

Enable HLS to view with audio, or disable this notification

New-ish bike and struggling to dial in fit. I've always felt this bike is a little cramped, and I've been having lots of pain on the outside of my palms, upper arms, and back of shoulders. Used velo fit on the trainer with the shock locked out. It had me lower the seat about 2 cm in total, lower the bars, and shorten the cockpit. Still feel way too much weight on hands. Seat feels really low, especially on climbs. Ready to give up bc it just hurts and my other bikes don't (and fit very differently).
