What drivel. I dare you to point me to the theory of mechanics that validates your assertion. (And, before you attack my knowledge base, I have taken the trouble to study the physics involved in some depth).If one rider - of any skill level - rides a 26" bike, and then a 29" bike, their line in a corner is gonna be wider. It cant be as tight.
Skills are essential, but the physics of bigger wheels mean that it just cant be the same corning approach / technique.
Ok so you have both studied the physics and disagree on the interpretation, welcome to the world of science (mind you no need to use the disparaging term "drivel", not an engineer by chance are you).What drivel.

I'm not much for science but in the latest amb Jenny Fay (2nd short course 4th cross country at nats) is quoted "next year I will probably switch to a 26" bike to get around the turns a little easier" , I suspect she's a better rider than me, maybe physics has a bit to do with it, bmx v's 26" pump track times suggest to me that there are two ways to get around a corner faster: shorter wheelbases (requiring smaller wheels) or MAKE THE CORNER WIDER...Ok so you have both studied the physics and disagree on the interpretation, welcome to the world of science (mind you no need to use the disparaging term "drivel", not an engineer by chance are you).
Suspect mittagongmtb has hit the nail on the head, its the rider more so than the bike. Based on my experiences returning to mtb after a significant layoff (kids!!) my initial trepidation (older = more risk adverse) resulted in hunting through corners I now confidently rail on a tighter line.
What interpretation? The original assertion had no basis in physics. Ergo, no interpretation required.Ok so you have both studied the physics and disagree on the interpretation.
Yes, it's not so much the wheel size but along with bigger wheels, most 29er's have a longer wheelbase than their 26" equivalent.What you've said sounds like bollocks to me. If you get a car and fit bigger rubber it still has the same turning circle. Wheels size doesnt determine the turning circle.
Wheelbase does. Maybe your trails are being ridden by longer bikes eg downhill bikes?
Dude - got some sand in your va-jay-jay?What drivel. I dare you to point me to the theory of mechanics that validates your assertion. (And, before you attack my knowledge base, I have taken the trouble to study the physics involved in some depth).
Gyro effect making it harder to lean the big wheels over....What drivel. I dare you to point me to the theory of mechanics that validates your assertion. (And, before you attack my knowledge base, I have taken the trouble to study the physics involved in some depth).
While that's possible, it's unlikely.Gyro effect making it harder to lean the big wheels over....
Now THAT's interesting. I wonder what could be behind it?As I said before I don't think its a wheel size thing just a rider thing. While corners are blowing out I'm finding less braking stutters.
You've answered your own question..... same thing happens on all tracks. Take for example Appin or Yellowmundah - high use, high speed - people will blow the exits, especially if flat or off camber.The situation here is that we are getting more new riders, including roadies now on xc machines, and we are going from a pretty relaxed crew of mainly social riders to a more competitive feel, races are becoming more regular here, riders are recording "hot laps", more riders are heading away to race (hence training at greater intensities) and rider and lap numbers are way up.
The issue here isnt cutting corners, its people running wide and widening those corners. If corners start getting cut I simply drag logs accross to block them
So, based on the above discussion, riders are maybe trying to carry too much speed through corners, inexperienced riders are using the relatively flat obstacle free corners and blowing them out with too much speed and this would be happening with or without the bigger hoops.
Is this whats happened at older/more popular trails? Esp interested in what happened elsewhere in the days before 29ers
In answer to previous posts, the country out here is undulating, mostly grassy woodlands (with Callitris in dense swathes in places) great for open flowy fast trails, the corners in question have been fine for the last 8 years but blowing out over the past 6 months, and thats coinciding with the influx of newbies on 29's and roadies getting into xc.
Intersestingly the riders who are blowing the corners are the most active and interested in building berms in those places so as to maintain their speed
I know your poking fun but what a foolish boy!Make the corners tighter and eradicate 29er's. Sounds like a win/win to me.

Once you go 29 you never go back!
Na it's just the UCI trying to merge MTB with cyclocross and 29er riders failing to realise a 29er is just a Cyclocross bike for riders to scared to run drop bars and too inept to use rim brakes.could it be that over the years trails have adapted to the more clunky 26er, then along comes the quicker rolling 29er and hence we are seeing an evolution in trails to the superior mtb.
