What wheel size to stop crashing ?
OK, on the face of it, it’s a pretty daft question. But we’ve done every other wheel size discussion to death, so why not this one 🙂 Do you think the wheel size has any effect on how frequently one would crash? On the face of it, all things being equal, you’d think a bigger wheel would result in fewer spills as it can plough through more stuff so should be more forgiving when you get it wrong.Posted 4 years ago
Seriously? You opened a thread (with a pretty clear title) just to post that you weren’t interested in the question? Slow day is it 🙂
Oh well, as I said, it’s a daft question really and I guess I’m in a minority of one in caring whether a larger wheel might affect the frequency of crashes.Posted 4 years ago
I’ve never fallen off a 29er, after owning a variety over 3-4 years. Realised when reading the topic, every fall I’ve ever had has been on 26″ wheels. Bizarre.
Given the evidence, it’s 100% impossible to fall off 29ers. 650b should be possible to fall off, but it’ll be harder than on 26″. This is why you see so many videos of BMX riders falling off.Posted 4 years ago
Wow, multiple data points and percentages. Maybe we should publish a paper 🙂 Sorry, must stop taking the piss out of my own thread. Yes, it’s a slow day 🙂 A computer programme that needs prodding from time to time, so I’m stuck in front of the screen but don’t get enough time between prods to do anything useful. You’ll be glad to hear that it’s almost done now though.Posted 4 years ago
I fell off a 29er on my first go. In fact, I’ve fallen off every wheel size.
Front wheel stability (with only a small risk of explosion) and small rear wheel for acceleration (to get you into out of trouble )
You could wheelie when you needed to accelerate, like cartoon cars, lowering the rolling resistance and getting the big wheel out the way.Posted 4 years ago
OK, I realise that nobody is going to take this seriously and that’s fair enough. Any differences are probably too small to matter in practice, but it’s still bugging me.
If a certain fraction of crashes are caused by the front wheel getting trapped in some way and a larger wheel is less likely to get trapped then a larger wheel should result in fewer crashes.
But what about the effect of head angle? Is it true that a slacker head angle also makes it less likely that the front wheel will be trapped/stopped by an obstacle? If so, it could be the case that (say) a 67 degree HA with a 26″ wheel is just as resistant to being stopped as a 69 degree 29er. If not, then the 29er is (theoretically) safer and I can shut up about it 🙂Posted 4 years agochiefgrooveguruMember
I’ve fallen off my 26 lots but never fallen off my 20 so clearly smaller is safer!
Seriously though, I think greater trail (head angle, wheel size, offset combination) and longer front-centre is safer, as long as you ride with enough dynamic weight shift to get the front wheel to grip in corners.Posted 4 years ago
