New trail (trials) obstacle

Someone has moved a big log in to one of the gullies on one of my local trails. To give you some
idea, the gulley is a couple of bike lengths on each side and fairly steep. At the bottom, the log
is about a foot in diameter, but where you cross, it's about 6" above the ground. This means it's
too high to roll over without mashing the chainring.

It puts you in the difficult position of trying to wheelie whilst the front wheel is well below
the rear. I managed to get the front wheel on the log, but then I was in another tricky position
of trying to get the rear wheel over and lift the front half way up the other side. Hmm, not easy
and I'm still not sure of the best course of action.

Only had a couple of goes at it this evening, but I'll come back to it soon enough, and will
clear it 🙂

Keep trying, it will be accomplished. Remember, its all about how you transfer your weight. As
they say in trials...throw your body and the bike will follow (I tend to disbelieve that most of
the time :-))

Throwing the bike trials-stylee is all well and good, but I've got the saddle set up for XC (and I
don't want to lower it, as it's in the middle of a ride. And it makes it more challenging). I'll
work out a way round it. Er, I mean over it 🙂

THat's your problem (and mine, truth be told) You have to have the faith - anything less than full
belief and you finish up looking like a prat (in my case) ;-(

I thought is was, "Throw you body and the ambulance/Medivac helicopter will follow." At least that's
how it works for me!

That sounds very fun, good riding.

C'mon bomba - use your bmx skills. How about a 360 nosepick, or 180 nosepick to fakie to revert
out... or put some pegs on, maybe just a rear peg (you don't want to look stupid) and try an icepick
to over etc. Show that sucker who's the boss.

Being a little bit more realistic - try approaching with a bit more speed, lift the front wheel and
just clip the top of the log, this should give you enough upward momentum to be able to get the rear
wheel at least on top if not over, then just ride out (throw a barspin on the way out obviously).

Surprisingly, I've considered most of those. On a normal log on the trail, nosepicking it,
tyre-tapping it or nose-bonking it would be possibilities. Doing it on a log at the bottom of a
gulley is just going to lead to me piling in to the slope on the other side.

Strangely, the 180 (more like 120, actually) nosepick is one that I'm giving favour to. I figure I
might be able to flick the rear over to the other side of the log, and then haul the front round so
it's pointing up the slope, and then hop out.

Yep, thats what I initially thought of, but I got a bit carried away somewhere.. Will doing this
leave enough momentum to get out the other side?

If it was over here the Barneys would pile up enough sticks to be able to ride over the log without
touching it. Of course the sticks will get caught in your rear wheel ripping out half the spokes and
derailleur.

I don't think my trails see enough traffic. However, there are tyre marks where people have
ridden round it.

No. It's basically going to involve stalling and then hopping out, or trying to ride out in
lowest gear.

Okay Bomba, looked at in more detail.

First of all, your definitions of 'a bit steep' and 'a couple of bike lengths' are a bit
vague. Tut tut.

I we assume 'a bit steep' is a 30 degree slope and a couple of bike lengths means two standard
wheelbases = 2*42" (approx) = 84" then to find the gap :- Determining one half of the gap, i.e.
dividing the gap into two RH triangles, cos (30) = x/84 x = 84 * cos(30) x = 72.7

Therefore the total length of the gap will be (72.7) * 2 + log diameter of 12" which works out to be
157" or 13'1".

Repeating this for other variables of 'a bit steep' and 'a couple of bike lengths' give: using 'a
bit steep' as 30 degrees and 'a couple of bike lengths' as two total bike lengths i.e. from tyre
edge to tyre edge i.e. (42" =26"😉 * 2 = 136" gap length is 20'8" using 'a bit steep' as 45 degrees
and 'a couple of bike lengths' as two standard wheelbases = 2*42" = 84" gap length is 10'11" using
'a bit steep' as 45 degrees and 'a couple of bike lengths' as two total bike lengths i.e. from tyre
edge to tyre edge i.e. (42" =26"😉 * 2 = 136" gap lenght is 17'

So in all cases the gap is definitely jumpable with the addition of a lip, I suggest template No. 10
for the 17' and 21' gaps, template No. 6 for the 13' gap and template No. 5 for the 11 footer.

It's too wide to clear with a lot of speed and a bunny hop, but not far off. A lip would certainly
make it clearable.

Hopefully, I'll get out tomorrow evening and go and measure it for you 🙂
