My wife bike fit

What do you think guys about the fit of my wife's bike? It's Triban RC520 size M and Im thinking about upgrading her bike to Cube Agree C62 SLX size 53 but I want to be 100% surr because it has integrated cockpit and changing it will be kinda expensive 😵‍💫 Any input would be of great help, thank you in advance!

Edit: She is 172cm Inseam 82cm

Knee pain is wrecking my rides – need some advice before I lose it

Hey everyone, I’m hitting a wall here and could really use some input.

So, about two years ago, I was just out for a chill ride when bam: sudden sharp pain in my right knee. It started acting up every time I hit a climb. I took a couple of weeks off, felt like I was back in the game, but then...oof...the same thing happened, but this time in my left knee.

I was pretty rattled, so I bit the bullet and paid a pro bike fitter to dial in my position. Turns out my saddle was way too low. After dropping a decent chunk of change, my bike felt like a rocket and the pain just vanished flats, climbs, didn't matter.

But here’s the kicker: over time, my saddle started slipping down bit by bit. A few weeks ago, that left knee pain flared up again. I tried to reset the saddle height myself, but the pain is still gnarly. I’m fine on the flats, but the second I put down power or hit a climb, it’s game over the pain is absolutely brutal.

I’m on a Cannondale SuperSix Evo, mostly hitting alpine passes and road rides. I’ve been training for an Everesting attempt, but right now I’m pretty desperate. I’m 35, and honestly, I’m just tired of icing it and lathering on creams.

Have any of you dealt with this kind of recurring BS? Anything concrete I should be doing besides just spinning my wheels and hoping it goes away? Any advice would be a lifesaver.

Lower Backpain on longer rides

Just wondering if is my bike fit.
After 2hrs on the bike I get lower backpain, and is gone by next day.

Honestly I had tendency to have backpain in long walks too which I overcame doing a lot of back in the gym. But seems for the bike is not enough.

After watching the video in realize my seat maybe is a bit too high?
Note: you can see my left leg, which is about 1 cm shorter than my right. Any hint on how the leg difference can be adjusted I appreciate.

Hands, knees, feel allright.

Thanks for any help.

Left hip pain

Looking for honest criticism of my bike fit. I have had hip pain for the last 15 years from an old sports injury. I completed a longer ride for me this weekend and it seems to have flared up again pretty good. Looking for any feedback to improve. Thanks in advance.

Feels close, but heavy on hands

I start getting some hand numbness, manageable with moving around a bit over the course of a 3h ride.
Same issue with feet, but I think that may be my shoes. Feels like I have space, but might be just snug around the forefoot at the widest part.

Drop the saddle a few mm? Forward a few mm?

Pressure at the front

The other day I posted a video, and I was told to try moving my saddle further back, so i did. The main issue is that I’m feeling a bit of pressure at the front of the saddle.

I was also told to record some video of myself riding in the drops, so here’s that.

I’m still feeling pressure at the front of the saddle, and I find it difficult to get my weight back onto my sit bones.

Could my saddle perhaps be a little too high still?

For reference, I’m 176 cm tall with an 85 cm inseam.

I’ve tried tilting my saddle down just a tiny bit, but it only takes a very small adjustment before I feel like I’m sliding forward on the saddle, which then causes pain in my hands.

I’ve tried countless saddles, and the SQlab saddle I’m using now is by far the best one I’ve ridden.

Lower back pain

Hi everyone,

I've been chasing a lower back issue for quite a while and I'm trying to figure out whether it's primarily a bike fit problem, a mobility issue, or just my anatomy.

About me

  • 191 cm (6'3")
  • Wingspan: 198 cm (6'6")
  • Inseam: ~93–95 cm
  • Torso: ~70 cm
  • Arm length: ~60 cm

Torso length and arm length should be taken with a grain of salt, we dont really know what were doing

I have limited internal hip rotation. I originally started cycling because my TFL couldn't tolerate longer running distances.

I'm generally not very flexible, although I can touch my toes while standing quite easily.

I also have flat feet and will be seeing an orthopedic specialist in about 6 weeks regarding insoles.

Strength isn't really an issue:

  • ~12 pull-ups
  • 440 push-ups in an hour
  • 140 kg deadlift
  • I have been bouldering, so my core should be fine too. Nothing amazing tho

I've recently started strengthening my glutes (glute medus or whatever). I do tend to get lower back pain on car rides as well.

Bike

  • Kona Sutra LTD 2022
  • Size 58
  • Stack: 660 mm
  • Reach: 405 mm
  • Stem: 50 mm
  • Cranks: 175 mm
  • Saddle: stock WTB (~145 mm wide)
  • Sit bone width measured at ~130 mm

Symptoms

After about 20 minutes on the hoods, I start feeling discomfort and eventually pain/numbness in my lower back.

Things that make it better:

  • changing hand positions frequently
  • riding on the aerobars (surprisingly much more comfortable)
  • riding hands-free for a few seconds
  • getting off the bike pretty much immediately relieves the pain

Things that make it worse:

  • long climbs
  • staying in one position

I can still ride 40 km (90 min) with only mild discomfort if I keep changing positions, and I've even done several 8+ hour rides. It's manageable, just annoying.

Things I've already tried

  • Lowered the saddle slightly.
  • Moved my cleats slightly rearward.
  • Adjusted the right cleat to better match my natural foot rotation (my right foot naturally points outward).

My question

Watching the video, does my hip movement look excessive or abnormal? And am I sitting too far back on the saddle? I usually notice myself scooting back on the saddle quite frequently, which I thought might strain the back. But watching the video, it kinda looks like Im too far back on the saddle.

Could this point toward limited hip mobility/anatomy, or does it look more like a bike fit issue (saddle height, reach, etc.)?

I'd really appreciate any feedback. Id love to do endurance style races/challenges, but Im far away from being able to spend a day in the saddle without breaking my back.

I Always have Saddle Pain.

No matter what i do, i always have pain. Mostly on the left seat bone. If i rise my saddle ist becomes more, but im already in the very low side.

Endurance Race (Not ultra!) focused.

Thanks!

5'6 with a 28/29" inseam; should I opt for 650B over 700c?

I've always aimed for the S 700C frames but have occasionally had some toe overlap when making turns. I'm mostly just commuting but looking to downsize from my frame to something like a Hybrid or MTB with a sloping top tube.

Is the size correct? 26 wheels commuter

Hi guys, few months ago I get Merida Albon tech (painted by previous owner) and turn it into budget commuter. After some time I’m wondering is size correct for me. I’m 173cm and bike is seat tube 47 cm, top tube 56 cm. Saddle is back to the max on seat post. Stem is 70mm.

u/Oliwer12310 — 20 hours ago

Frame to big?

Hello,
I have a Merida Silex in size M, and I was wondering if it’s the correct size for me. I’m 180 cm tall with an 83 cm inseam.
The bike currently has a 70 mm stem, 165 mm cranks, a 0 setback seatpost, and the saddle is positioned almost all the way forward.
Sorry for pedaling backwards. At the moment, it’s the best I can do.
Thank you!

Saddle after ride

Please see attached image of my saddle taken immediately after a one-and-a-half-hour ride. In your opinio, is there anything in particular to note? I should mention that I feel discomfort where the stitching on the outside bottom of the bib shorts (under the chamois) is placed. Also, I always seem to have trouble activating my left leg as much as my right leg when riding. Thanks already!

My butt hurt

Hello !
Its my turn to ask help 😅 M30 1m87 I ride a Canyon Aeroad SL8 for 3 years now, only 7k km with it. The bike was never very confotable for me but I was able to ride 3 hours before having little pain. I prepare l’Etape du Tour (yes in 2 weeks) and one month ago after a 5h ride I had pain in the left testicles. After that I started to move a little bit the saddle, angle, front/rear position and I modified the fit from a bad to a worse settings… On the bike I have the original saddle selle italia model x 145mm. I tried another saddle selle italia 135mm and it was not better. Then I measured the gap between my ass bones (120mm) and came back to the 145mm saddle. Now I’m back with "default" settings, inseam x 0,885 for the saddle height, saddle in the middle position (rear/front), and an angle near to 0 degree. The issue is that my perineum hurt and become numb during long ride.
I’m not new on the sub so I already now that my saddle is too high 😅 and honestly it looks too high on the picture but I think its adequate to my pedaling technique. Any tips would be appreciate. Of course I will not apply any "big" change 2 weeks before l’Etape but if a small adjustment can make the difference I will try.
I also attach a small video in the comments

Constant saddle sores/irritation. 3 weeks until a 4000km ultra-race, need advice!

​Hi everyone,

​I can't seem to solve an irritation issue right in the chamois area where it contacts the widening part of the saddle.

​I am currently riding a Selle Italia SLR Boost (143mm), which was recommended by three different bike fitters. Before this, I tried a Prologo Scratch (143mm) and a Prologo Dimension.

​I’ve tried using chamois cream, even though my bike fitters advised against it, but it doesn't solve the problem—it only delays the onset of the irritation by a couple of hours (I've tried Fissan and Buttr Endurance Chamois Crème). I have also tried high-end bibs like Assos and Santini (with the C3 pad), but nothing changes.

​In 3 weeks, I have a 4000 km ultra-endurance race, and I am seriously losing my mind and ready to saw my bike in half.

​Does anyone have any advice or last-minute suggestions? Thank you so much

Just to clarify, I actually used Gemini to translate my original post from Italian, so I apologize if any phrasing sounds a bit robotic or off!

Would you consider this a zone 2 training?

Hi.

I bought a Polar sensor, so I can take a look and try to keep on zone 2 HR.

Would you guys consider this zone 2 level training looking at this numbers? It was on Assault Air Bike.

I'm 39 and I'm not sure about my max HR, but rested is around 40/44.

Thank you.

Excessive hip/ knee angle at top

Hey.

I posted this video recently but I took a screen shot. I’m riding 155mm cranks in the picture. I’m curious if it looks like I could go even shorter down to 150mm? How are my knee and hip angles at the top?
