How a too-long MTB frame contributes to a crash

This is a skilled and strong rider who's on a bike that's way too long for her body. This led to a nasty over-the-bars crash. She would have been safe on a bike with steeper angles and less suspension, but that fits her properly.

    It's not the bike, it's a poor, oldschool technique and a lack of ability to adapt. She was much too far on the back of the bike with her butt much too low on the back wheel while she should be much more forward at the beginning with her chest over the stem, her arms fully bent and knees in a front of her toes and then should straighten the arms when she came over the edge. Actually, a smaller, shorter bike could cause even bigger crash with her poor technique.

    Let's speculate. What would've happened if she'd had a shorter bike? She was obviously afraid and was trying to get as far back as possible. He arms would've still been straight and he hips would've still been way back. I predict she would've gotten to the bottom BUT she would've fallen on her back P.S. or she could have lost her balance in the middle of the feature and fallen over to the side P.P.S. Long bike are made for a specific style of riding. And using brakes scrubbing down a speet feature is not it

    Hi and thank you!!! I run inverted riser bars on my trail bike. It’s often the only way to get the fit I need … and I’m statistically median height for a male. With big wheels and tall forks I fit most guys my size or smaller that way, and most women need inverted bars for a RAD fit. People at the companies that make bars say it’s safe. Tons of details on the book Dialed and in my mtb school at www.leelikesbikes.com. Does that help?

    To my eye as a professional MTB skills coach she looks strong and skilled. I can appreciate why she'd be nervous and a bit tense and just a bit too far back. But the issue is that her arm range was used up to simply reach the grips. There was no range left to manage the down angle. No stem can fix that unless it's mounted backward. A taller bar might feel more comfy, but it will actually reduce her arm range even more. The solution is a bike that's built for her size and proportions. Or her choosing trails she can ride with her available range of motion. She can learn some 'special' techniques to make that work better, but the fit (and her safety) will always be a compromise.

    I agree, she had an arch in her back and an inability to hold the bars straight and maintain the line. Also her butt is on the rear tyre so she is unable to use her legs to absorb the compression. She should have been more over the front with less of a squat in her legs. If her but had been more over the saddle she would have had heaps of reach. She was also moving too slow to maintain balance. I have short and long bikes, it really makes little difference when you have correct body position.

    @@cunning-stunt I agree she might have made it work had she been farther forward on the bike, but then her weight would be unsafely in front of the bottom bracket. That technique can work for sure, but the rider has to be very skilled. For most civilian riders, it's just not safe to be anywhere but perfectly balanced. Also, someone with legs that length will find steeps easier with a smaller rear wheel.

    perhaps the issue comes from "rolling" this feature rather than keeping a little speed and lifting that front wheel as the take off happens. Landing as much with both wheels simultaneously as possible. I don't know nearly enough to determine if bike size is an issue for the rider in this video.

    Lee's a legend, and I'm sure he has a point here. But I see a timid rider approaching a feature in a squat with arms already extended and already sitting on the back tire, with no where to go as she then goes down the rock roll and predictably gets pulled over the bars. If she had approached with more confidence, hinged at the hips with her chin closer to the stem, heels dropped, and legs straighter and then "pushed" through the roll I think this would have been fine.

    Rider ran outta rope. This is a problem with a frame which is too long, and also with bars which are too wide. They both limit how much you can move around on the bike, or have the bike move around under you. The ape-hanger bars really restrict how much "off-center" you can be on the bike. Same problem with long reach, you just have no arm angle to extend FURTHER once you are behind seat, if the bike is too big/long. it's a very common problem nowadays, with the bike shops and companies pushing the bigger/longer/slacker thing incessantly. One of the best riders I know is 5'10" and rides 680 bars, he says he can move around better without any restriction. I'm 5'9" and run 740s, for same reason. Not everyone is going 30mph in the desert when the control of a 810 bar is desired.

    First of all, there's no reason to be behind the seat in her situation - she should start rather slightly in a front of the bike and then move to the center. Second of all, a longer bike requires much more movement to be destabilized and getting lower makes it even more stable, which would help a lot in that case, but getting low does not mean to get behind the seat - that's an oldschool technique, completely obsolete and redundant with modern bikes.

    Yes bike looks a little long from her arse on the wheel but she looks short so a mullet could help her there. Mostly I see with this what I see in a lot of crash videos like this: being to slow and not dynamic on the bike so you can commit and ride through/down the feature as opposed to being a passenger. One she got to that lip she was just a passenger. She could have been standing a bit taller but in good hip hinge and more forward. Leaning back and pulling back on the bars lifted her front wheel. Being forward and still applying pressure to the front but being centred and low would have keep the front wheel on the ground the whole way through. That’s my unprofessional opinion anyway haha

    Many bikes are getting too long. You lose control when a bike is too long. She would have been able to keep the rear wheel down and pull on the front end near the bottom had the bike been shorter. I am not sure why the bike industry keeps pushing longer and slacker bikes on everyone. We have gone way past the sweet spot.

    she is too low and not on the bars enough as she reaches the edge of the rock roll. She is literally sitting on the rear tire and that is why her front tire breaks contact w the rock face, and then traction and control are lost. The bike doesn't look that oversized for her, but it is hard to tell from this clip.
