What are some good ways to initiate rear roll

[Xoo]

I've been working on endo pivot but am having a hard time initiating good balanced reverse motion so I can try pivoting via brakes on the rear wheel.

Is all pivoting with brakes or can pivoting mean pedal initiated spin or turns?

[spoke2570]

A short slope with rol in/out room is a god place.

Roll up the slope. Just as the bike is coming to a stop, bunnyhop. When you land the bike is going bacwards with enough energy to figure out what is going on.

I usually use the crank to control the rear wheel. If the wheel stops so does the spin.

For clockwise spin: As the left pedal comes up to level (forward) turn the handle bar left (sharply), and heave into that left pedal. A soft touch on the brake will give a little added control.

are you trying to learn to fakie (ride backwards)?
if so, it may not be the best way to learn to pivot on the rear wheel. You are best off learning to do it static (i.e. on flat, no rolling, etc.).

[Xoo]

Somehow it posted half of what I was typing. then posted the rest in a second post. :(

[Xoo]

I'd like to learn fakie too but I was actually asking on how to get some kind of rearward moment to static pivot on the rear wheel. If I could pivot 180 on front it might be a good setup into a rearwheel pivot. Right now I can only pivot a little more than a 90.

I havne't had much luck doing fakie's yet. my balance goes to crap fast with rearmotion and backwards pedaling.

on a fakie roll...from like a stand still. what you do is lock up your front brake and throw your weight forward. do a little endo and let it back down. as soon as your rear wheel hits kinda pump your weight backwards and slowly start pedaling backwards. to get out o fit you can do it a few ways. you can do a 180 bunnyhop. you can grab a handfull of your rear brake then do a 180 pivot. or you can kinda lay your bike over a little and give it a hard turn and let it pivot around the rear wheel....i hope this is what you were asking for...

[Xoo]

Yeah thats good help for a fakie roll. I guess I just need the balance to not falter during rear roll and pedal.

[Povi]

dont get ahead of yourself by trying a 180 pivot in either direction. that will naturally come later.

[Xoo]

I have notice3d that 180 pivots appear to require or at least be more smoothly achieved by pivoting your front tire before or shortly after your rear tire leaves the ground. Well at least in the Danny Macaskill video's that is what he does. Pivots to at least 90 the front tire very early in the move.

[Povi]

that true. i can only do rear 180's after doing a front 180. you need to know how to rock the bike proficiently also, because from rocking, you can keep the momentum going and therefore lead to a well executed spin

Staying off the back brake really helped me.

[Xoo]

With a couple more weeks of practice I should be able to nail it just like the intro to this vid.

:umno:

[Povi]

that is a half-cab (jumping 180 instead of pivoting)
that is very hard to pull without backwards momentum.

Staying off the back brake really helped me.

i used to always be on the rear brake when i did any moves where my rear wheel was off the ground. otherwise i would do a pedal stroke unintentionally. i found that as my hips got stronger and could hold a possition better i didnt need that brake. which makes for a lot smoother riding, cuz you can roll a little bit when you hit the rear back down. it also is more efficient by using less energy pulling levers and what not.

[thisthingz]

i think half cabs are fakie 180's.
you should work on other things first i think, getting a rear wheel hop helped me do rear wheel pivots.

[Xoo]

Yeah I'm not serious about trying the half cab just yet. or rolling endo's. I am noticing there are multiple ways to get something done. Like using partial brake vs. None or all brake, or using more/less body enlgish/flick vs. using more/less momentum. I've had a couple spills on the front lawn trying to use more momentum to get my 180's down. However they have taken a lot of the body english strength required out of the move. I was finding the lower momentum 180's I was running out of oomph at 120-180 range of the pivot. I haven't been pivoting my front tire with the 180 so that could be my problem too. I imagine physics works against me trying to have my hands gripping my handlebars 180 out of the direction I end up facing.

To be honest I'm only trying the 180 pivots only when my endo's are 'on' sometimes I go out and they aren't 'on' enough to be trying pivots.

you should work on other things first i think, getting a rear wheel hop helped me do rear wheel pivots.

I think you're right my trackstand, hopping and rearwheel hop need to be stronger. Or in the case of rearhweel hop, existant at all!!

[Xoo]

Just found my Front tire to seem wobbly. Did some further checking and the bolts mounting the Hope caliper were loose by quite a bit. Maybe this will change some of my inconsistancy in my Endo's. I went ahead and checked everything else on the bike the top bolts on my Rim Brakes were somewhat loose too.

How often does stuff loosen on trials bikes? Should it be a daily check or do I need to start using some loc-tite?

[Xoo]

Yep, tightening down the front brake caliper made ability to do endo's less random. I hope I didn't go to long with it that loose, I assume it was getting progressively worse since it first started to loosen and I've caught it before anything got boogered.
Back wheel hop position feels more comfy too, maybe that was the stretching and yoga.

[Povi]

just make sure every now and then the bolts are tight. nothing daily, but just whenever it comes into your head

[Xoo]

I still get a slightest wiggle but I've felt and it's not the brake,caliper, or headset it appears to be the wheel gives somewhere from the hub to the tire which I am assuming is normal?? It's not a lot of wiggle but there is some if you tug front and rear.

[Povi]

it may be.

wobble the whole wheel side to side to see if there is any movement there. if there is, then go to a bike store and ask them to tighten your hub cones. simple

if it doesnt wobble side to side then check spoke tension to see if the wheel is in equal tension.

after that, if there is anything wrong and you are concerned about your safety, just go ask someone with knowledge - i.e. a bike shop mechanic or whoever

tyre roll is normal and so is fork flex, so you dont have to be worried about that

[Xoo]

Finally an excuse to show off my trials bike to a local bike shop and see if anyone even knows what the hell it is. I could weight it while I'm there too. I don't have a reliable scale at home.

[beastoftheeast]

blue loctite stuff that comes loose and dont tighten it super tight.

[Povi]

over-torque = death

[Xoo]

Yeah I fear the overtorque on alluminium components. I don't think I've done that. I'm pretty sure it's between the hub and rim. I'll have to learn how to check spokes, never really done that first hand.

[beastoftheeast]

i stripped an hs33 mount recently. got it helicoiled, good to go again. i think it was just a shitty hole and there was not enough threads there.

to check spoke tension squeeze 2 spokes that are parallel on a wheel a bike shop built and on your trials bike and compair. if your spokes are too loose you will probably know it though because the wheel will creak under pressure.
