top mount them, ive ridden them topmounted and they work fine

also for bearings ive had good results with bones swiss's but i am now experimenting with inline bearings, they seem to be much better built and are designed to obtain higher speeds and a smoother ride.

edit: also they come in packs of like 16 bearings os you get more bang for your buck

link it up!

Bones super 6s are some amazing ass bearings if I may say so.

vicious is what im running now havent tried the bsb's but they seem nice

I bet inline bearings withstand side load well.

Ill bet that inline bearings are the same as skateboard bearings...

No!..... you serious???

Yep. I'm running Speed Freak ABEC 7's as we speak.

So our roads are different (wet/dry/wet/dry weather makes the tarmac/concrete set in different ways so, things respond differently over here too, not that i've expeirenced any foreign roads, but my guess is that yours are alot easier and better to skate

where are you based in england?

if your feeling bummed about not getting speed, get your mates to bump draft you. if your skating a hill below 30mph you have to be really close to get a draft, so just make sure your keeping level with your mates on the push, then just tuck in behind them when they stop pushing. don't be scared to ask for help, im always happy to bump draft someone!

please dont use english roads as an excuse, british guys shred just as hard as europeans and americans!

if your in the southeast of england, we're holding an outlaw next weekend, il pm you the link to the FB group.

apologies if all this sounds patronizing, really don't know what your skill level is!

**gavmck** · 11-12-2009 06:35 AM

Don't you mean South East Oli? heh!

Where are you getting 47mph in the UK? Fasty fasty!

To be honest, it's probably your push/tuck and not your weight. I am a fat bastard and weigh about 14 stone. I was COMPLETELY REDICUOULSY smashed past at high speed by Mike River who is way smaller then me but has a sick tuck/push.

On your demonseed purchase, you said you just wanna stick corners. The DemonSeed is probably the driftiest board I've ever ridden. Would recommend you try a topmount, especially if you've never got wobbles. Also that DSeed with those trucks and wheels is probably gonna get railbite unless you topmount it.

Come to the High Wycombe outlaw race!! There speeds shall be judged! and cornering!

english pavement slides badly huh.......I beg to differ

A new setup and/or lead in your leathers to go faster is just silly. Sack up and eat food/gain muscle weight if you want to be faster in straights, as well as working on your tuck.

Being lightweight you have a natural advantage when it comes to cornering so get better at drifting and gripping corners and you'll be able to smoke people on technical hills (which are so so so so so much more fun than straight bombs.)

Just skate more.

Like he said. Seriously, if extra weight was an advantage, why would people pay 400usd for a dee-lite? Light is always better with speed sports. Gravity's the same for evrybody, nomatter what the weight. Look at the IGSA podiums over the past year and check out the shape of Siegrist, Pilloni, Switzer. They're not heavy guys. Back when the sport was new and the races were straight you had guys like Striker and Jesse winning races, but you want to be lean and mean nowadays to make all those tight corners. Enjoy and embrace.

**thokk2** · 11-12-2009 08:59 AM

####!!!!! I just typed a huge essay telling you all about rolling resistance on straights and turns, momentum, weight and aerodynamics... But then I clicked something and it went away...
So you don't get to hear it.

To sum it up- weight does not affect speed on a straight. Only rolling resistance and aerodynamics do.
So if you are slow, work on your tuck, clean your bearings and get harder wheels.

Also, pics of your tuck vs. your friends tucks would be greatly beneficial.

Aye okay, but im sure the number one bomber isn't 8 stone? And i live in Plymouth, in the southwest. Also i never said it's hard to slide in england, i said it's easy to slide in england, and i dislike sliding alot. Dee-lite are also just for show, im sure if someone raced a non dee-lite then again with the deelite, he'd have the exact same time. Who knows.
I just need to push harder i guess.

Plymouth woop!
I hope you hang with the Plymouth crew wot had that race just the other day.
JJ came third in that race and he is a skinny waif who's not very tall either. I wouldn't be suprised if he was under 10 stone. He also completely smoked me at Eastbourne by almost 10 seconds! 4+ stone lighter, 10 seconds faster.

See if you can analyse your tuck, something may be slowing you down. If you can ride with someone faster than you a bunch, go do that and try different tuck adjustments and see what makes you faster.

Most important, go ride with a bunch of people who are better than you. Look up Stewart Lees and Liquid boards on facebook, lots of gnar plymouth sessions happening lots that should teach you how to go faster!

would have liked to see the scientific side behind it. My brain is so fried from exams I cant get it right in my head. Electro-techniques messing my brain around!

Ok, I'll type something up here in a minute. Just be patient.

I'm a shop rider for Liquidboards, and a great friend of Stewart and Matt Elva. i dislike JJ alot (Other reasons besides). These are the guys i normally skate with

And i was at the LBS jam :P
(Btw i'm the one who helped build liquids website :P design the t-shirts and helped with the 26 Mile push)

**thokk2** · 11-12-2009 09:59 AM

Here's my essay. Haha.
I have no sources on this, it's just theory from my head, so correct me if anything is wrong.

Two objects of equal aerodynamics will fall at the same speed. (A ping-pong ball and a cannon ball, if dropped from the same height at the same time will hit the ground at the same time.) But with skating you must also consider rolling resistance and momentum.
A small skater has the ability to get into a very small tuck, but there may be gaps in the tuck. Where as a fat skater may have less holes in his tuck, he may not be able to get very small. So each must find a tuck that is the most aerodynamic for his body.
A heavy skater will compress his wheels more, so needs to ride harder wheels to create less rolling resistance. And a lighter skater can run softer wheels. (I'm not sure how bearings play into this, so I won't pretend I know.)
Therefore, if a heavy rider and a light rider both have equal rolling resistance (by running different duro wheels) and equal aerodynamics (by having different tucks) they would be equally fast, but only in a straight line.
If you introduce any uphill or turns things change. A heavy skater has more momentum, so in an uphill section he will carry his speed farther than a light skater. In a turn a heavy skater will have more speed coming out of the turn than the light rider. But the heavy skater has more momentum and has a higher chance of sliding in a turn, therefore loosing speed and being slower then the light skater who does not slide. This can be fixed by running softer wheels for the heavy rider, but then he will be slower in the straights.
Therefore, weight, if accounted for while perfecting your tuck and wheel shopping, will not affect your speed.

Hah! That shows me then! Good stuff to hear!
Sounds like you've got it all then, just need to skate some more! GNAR!
