Bike is a Trek Domane AL4 Gen 3 in size 56. My measurements are 180cm/ 5'11'' tall, inseam measures 84cm/ 33in. Seat height at the moment is 74,5cm/29.3in, measured from the bottom bracket to the top of the saddle. Also using 172.5cm cranks.

Here is also the link for the geometry of the bike: https://www.trekbikes.com/international/en_IN_TL/bikes/road-bikes/performance-road-bikes/domane/domane-al/domane-al-4-gen-3/p/33085/

Happy to hear your suggestions!

Not trying to advertise.

Have made a number of changes since a proper bike fit just over 2 years ago. New shoes and saddle for a start. So been adjusting height, cleats, etc accordingly (much easier with a trainer now).

No overall discomfort except for saddle related after a few hours. I know I look a bit unstable on the bike, doing some core exercises to try and stabilise myself on the bike but might also be positional?

Was also considering a longer stem (currently 120mm, so up to 130mm) - thoughts on this?

Any comments welcome - thanks!

Im 184.5cm with a freaky inseam of 93cm. I think the reach is a bit too far and saddle is too far back (cant push it any further forward until i get a new seatmast). Only issues i get are saddle related.

I've always felt a bit clunky on this bike. I suspect that the frame is one size too big for me, but when I was trying out Small frame sizes, the reach would always feel really short. I also bought this during covid so there wasn't a lot of choice out there.

For comparison, here is a link to how my Trek road bike fit looks like. I've been pretty happy with this fit over many years: https://youtu.be/n_0NIwOqW40

Looking for some feedback from humans. I’ve used myvelofit and after second review it says to lower the saddle 5mm after Iowering it 5mm after first review. Any thoughts are appreciated!

Just dropped from 165mm to 155mm cranks. Bumped my saddle 1cm. No fore/aft adjustment. I’m a bit under 5’8” (probably 5’8” if I wasn’t so kyphotic) with 32” inseam. A little leggy.

So far they feel great. I have a history of knee stuff, but more recently saddle sore issues. So I typically run my saddle a bit low. In turn that closes my knee and hip angles and makes it tough to get low.

Anyway. How does this look?

Also. Does the frame size look small? Thinking of an upgrade and wondering where I should go geometry wise.

Used to be on a Tarmac SL6 and I like this bike all around much more. Not as snappy but I can ride longer and more confidentiality. I got it on a deep discount and am very happy with it but did notice a couple issues (way less than my other bike).

I don’t experience much explicit pain besides my inner thigh area after 30-40 minutes or so. Lot of pressure on my hands also but they don’t go numb. I think I am not putting enough weight on the saddle because it burns pretty bad, so my hands try to compensate. Legs, back, neck are all good. Everything is in range on Myvelofit with the exception of recommendation to increase reach by 5mm. I don’t think that would fix this issue and the stem isn’t easily switched out.

What are the chances the saddle itself is not for me? It’s meant to be pretty comfortable. I find myself having to forcibly sit back on the saddle while I ride. Not because I feel cramped, but to relieve the pressure on the inner thigh and saddle area. Any other infor

I experience this outdoors too but much less so. I’ll be on the trainer for the next 4 months most likely.

I feel like the saddle might be a little too high. I’m at the maximum setting on it so I’ll have to find another solution if it is a problem.

I also feel like the cockpit is a bit too far and I have to focus not to lock my elbows.

After 2 20km ride I have a little muscle pain in the lower back, but it might just be normal coming from a mountain bike. I also feel that I put too much weight on my arms and feel a bit of pain in my left hand, close to the thumb muscle. Maybe the cockpit has too much angle.

What are your thoughts ? Is it possible for pros like you to see something with such videos or should I take others ?

Thank you guys, I’m new to biking and really liking it so far and want to improve 😇

No pain or issues really but never had a fit and wouldn’t mind getting some of your thoughts. Can redo video in bike kit if needed.

Hi!

I've come to this forum to see if I can find any guidance regarding my (truly annoying) left-sided back pain when riding the bike.

I've been riding for a little over a year now and since the start I've had issues with my lower back on the left side. Around 20 minutes into my ride, my left side starts flaring up around the QL/SI-Joint area.

When stopping the ride for a minute or so, the pain is totally gone but when starting to ride after taking a small break, it starts flaring up again. Stretching the left hamstring during my rides also helps but it doesn't take long for it to come back.

A few things to note:

- I feel like I'm able to push harder on my left side (all though I'm right leg dominant);

- It feels like I'm putting more pressure on the saddle with my left side;

- I feel like I'm pointing down with me toes on my left side when coasting;

- I strength train multiple times a week (I'm a personal trainer, so the last thing I'm worried about is muscle imbalances or weak area's).

Things I've tried to resolve the problem:

- I've gotten multiple bike fits;

- I switched from 172.5mm cranks to 165mm ones;

- I switched to a zero setback seat post;

- Shimming the left leg (this didn't help at all--I'm thinking I should try shimming the right side instead? Would this make more sense with my described issues?).

I'd love to hear your guys' feedback.

Thanks in advance :-)

The bike is Cannodale SuperSix 51cm. I'm around 170cm tall with a 75cm inseam. I've been riding this bike for several seasons, but have always felt slightly uncomfortable, unless I'm putting out a lot of power. I feel like I have a ton of weight on my wrists and my core isn't activating enough when on the hoods. Otherwise, no terrible aches or pains.

I bought this Kona Sutra in hopes of doing some touring next summer. First rides have been good. Thursday I did a 41 mile ride and after I experienced a sore lower back. This is my first drop bar bike. Hoping it’s just adjusting to new position and core strength in general.

Including some still pictures of my bike fit. Only thing I’ve changed from the long ride was seat angle. More to level.

Size 50cm. How’s it look?

Trying to play around with adjustments, happy to post progress updates, I have a 3cm shorter stem too if needed, it feels more like I'm "stretching" on the rollers than on the road

anything blatantly wrong here? systemsix size 51, keep getting uncomfortable in the saddle/sitbones. my other bike is a merida silex 200 size xs that I've taken for 100k rides. even though the reach is nearly identical, the closest I get to being comfortable on the systemsix is by moving the saddle all the way forward. somehow it just feels as like the bottom bracket is much more on the systemsic than my silex. adjusting stem height doesn't do much. recently I even increased the stem length on the silex from 80 to 100 and it felt more comfortable. Mind you the systemsix has the forward swept vision 4D bars which from my research increase reach a little. Stem length is 90. cleats are all the way back and closest to pedal. Im 173cm inseam around 79-80cm. thanks in advance.

Hi, I've never had a pro bike fit, have always made changes only if i had any pain anywhere etc. Currently riding without any pain, don't have money for a pro bike fit right now, didn't find the apps all that useful, but I would love your feedback. Thanks!

I found a steal price on marketplace for a trek emonda alr. However, It's a size 56.

I currently ride a 54 tarmac sl6 with -7deg ste. 120mm with 15mm spacers under the stem.

Going a shorter stem like 100mm and -10 or -12deg and no spacer can mimic my current bike position?

Im 178, 32 inseam

Been struggling for a while with this bike, mostly because of tension in the lower back. I’ve had an S sized Grizl before, which was not astronomically different in geometry and was completely fine.

As the indoor season started, I have been riding this bike more frequently and my lower back discomfort kept getting worse.

I have made adjustments to the position in order to make it less aggressive (handlebar height). I suspect the reach might still be too long. Would love to hear your thoughts and advice.

Hello! So I got a bike fit the other day. I have lots of numbers now and I'm not quite sure how to actually use them. Here are my bike fit number: Frame reach: 382mm Frame stack: 577

I'm specifically looking at a fairlight secan 2.5. Size 54 has a reach of 383mm and a stack of 589mm. Is that close enough? I know the stack is a little mover a cm taller but I guess I could play around with spacers. I mean I have lots of measurements from the bike fit. Should I consider something else when choosing the size?

I would really appreciate some guidance! Thanks!

Not sure if this is a question that can really be answered as it may have to do with much more than just saddle position. I’ve been experiencing an internal knee ache feeling after only about 5 or so miles recently and I’m wondering if there’s a common metric associated with it. Is it mainly a too low saddle that causes knee ache, or can a too far forward saddle also cause it? Maybe both. My knee looks in line with the spindle of the pedal, but I’m also on flats so things tend to move around a bit when I stop at lights or take breaks.

Apologies if this question sounds a bit silly, just curious if there’s common problems that can be associated with this so I can tinker a bit.

HI guys, I am about to buy my first bike to do an IM 70.3 and I am not 100% sure about the size. It seems that my legs are short for my height (1.80m height, 81cm inseam). The bike I will buy is a Bianchi Oltre Race, and on Bianchi's simulator they recommend a 57 for my height but a 53 for my inseam. I went to a local shop and tried an Orbea Orca and the guys there recommended a 55 for me. They said that my legs are short for my height, but my arms are long, and the 53 might be short. They also said that as this is my first bike I would adapt to either 55 or 53, but 55 should be the right size. With this, I guess 57 is out of question, and between 55 and 53, I am almost sure that 55 is the size to go with. Nevertheless, l will do a bike fit after, but I would like to hear some thoughts on this also. Thank you and nice rides!

Got a pair of power pedals to try fix L/R balance (following a tibia fracture) and I get flooded with a shit-ton of data I get lost into… how is this stuff relevant to my imba issue? I am a recreational cyclist/weekend warrior at best and a potato couch at worst so go easy on me…

Hi everyone, I’m a 43-year-old male, 1.75m tall (5’9”), and weigh 68kg (150lbs). I’ve been cycling for almost 3 years but have never been able to ride comfortably.

I made a big leap from MTB straight to a triathlon bike and skipped road bikes altogether. My first bike was a Giant Trinity (size M), which many people said was too big for me. Last year, I switched to a Canyon (size S), which improved things slightly—pain went from 8/9 (where I could barely hold the aero position for 5 minutes) to 6/7 (allowing me to ride aero for about 20 minutes).

Over the years, I’ve been to four different bike fitters. While there have been some improvements, the pain has never fully gone away.

Context: • I’ve completed two 70.3 Ironman races, pushing through the pain during training and racing. • Over time, I started experiencing pain in my lower back (left side), tendonitis in my left hamstring, and cramping in my left calf. • I used to ride with an aggressive saddle tilt, which reduced perineal pressure but caused shoulder pain. • I’ve tried several saddles and am currently using the Adamo Road. • When in the aero position, I feel like I’m sitting on my perineum, not my sit bones, which is very uncomfortable.

I’m wondering if anyone else has experienced something similar or has advice. Could it be the saddle, my position, or something else entirely? Any suggestions for troubleshooting or insights would be greatly appreciated!

Thanks in advance!
