line A shows that the ass of sam is aligned with the rear hub.. making the weight of the bike n rider concentrated at the contact point on the ground and the bike. which creates lots of centripetal force on the ground which produces lots of force.. in physics the action is always equals to the reaction.. there fore the equilibrium produces the thing called traction..!! even if the course is wet.. the traction compensates the skid factor.
line b is the trajectory of sam ( in a curve motion to create lots of centripetal force
line c is his weight shifting techniques
a therfore conclude that speed = distance divide by time

@rocketman - short socks are faster... less cotton covering on legs means faster cooling of leg muscles for more efficient pedalling , cuz if ur legs burn up and cant cool down fatigue sets in faster....
i'd bet u didnt know that...... ;D
** talking of socks: jimi d-tor has nasty habit of using socks for tissue paper.. he goes up with 2 pcs socks and he vanishes for 20 mins then he goes down 1 sock less... heheheh ;D
regarding the sam hill cornering technique.........
from the position of everything its all good... cuz based on his speed and his entry angle "the law of physics" can answer it.....
he shifts his weight to give traction to the rear tire, once his rear tire hits the high area of the outside corner... he shifts center then thus giving both tires traction then he pedals out of the corner.... cuz once you apply power from your glide.. your bike will automatically stand 90degrees..... heheheh simillar sa moto n atv. ;D
executive category pro n non-pro.. hehehehe... norba n imba has executive A & Executive B , hehehe.... that might make prize money harder for race organizers hahaha additional category.. ;D
and for the Exec Dh bike.... any DH set-up will do for us as long as it dsnt weigh like 70 lbs ;D... thats gna be like hell-earth-hell pushing that rig up to the starting line.
Plus i'll bet on tech courses we'd be drained trying to arm-pump that behemoth half-way down..... if u can lighten the bike to sub-55lbs why not hehehehe......
plus what i noticed with the pinoy mtbikers are "they think that if they're heavy they also need a burly, cumbersome dh rig." ;D ....there are things called "stiffer coil springs" for rear shocks ;D
and dont worry bout the price, most exec riders can afford an excess of 200k/annum... ;D its a small price for enjoying what u love most.... riding ur bike down
the wife issue... dont worry, they only spite once when they ask questions why your bike looks different and you cant seem to give a straight answer without trying to change the topic? ;D
Trails: since most of us execs are office moles mon- fri we only get to ride sat n sun, right? but its family day... DUH
Tagaytay is the most conducive for FR/DH its cool, you have b10,ridge2,ridge3,holy trail, puppy's trail, lester's trail,villa dionisia, radar ni ricky. .... if its family day combo.... leave them somewhere in tagaytay where theres planty of family spots, bring driver, van, bike and head of to the trail then w8 for driver at the laurel, batangas municipal hall then ur back up. (always ride with someone).... thats 17kms=8-10mins down then an hour going back up via sungay or lemery
Grotto, Montalban for the execs looking for a good 1 hour climb and 4 minute descent this is the spot, the rock gardens and rut lines here have evolved since the last days it was used as proving grounds during the early days of pinoy DH. one can push to the nipa hut starting or the mama mary shrine... it is also home to the famous Boyet Camba "Camelback gap" which was erroded recently .....but hey grotto means bigger drops and sharper rocks... ;D
extendead.... oh really u didnt bmx? heh! you started mtb xc 96 cuz i see you,rocketman,bans,clarence,jake in PICC jumping over trash cans b4! Liar lair pants on fire!.... then u started DH 99..... when you inherited my muddyfox .... i have tagaytay pictures here at home ... evidence!
I wanted na to wear skin suits next race where can i buy them?
........u can find them at shops for triathletes hehehe ;D
one problem..... eh you know felix bakat tambok. djahi kasi dami audience hehehhee
....... dont worry tell them its power bar inside your pocket! ;D
if i wear baggy shorts over it, is the speed reduced?
..........why speed reduced? are you gonna run over 80kph for aerodynamics to take effect? ;D .... you read too much marketing bullshit from magazine ads... lol ;D
Since koya ernie baron died i have never ask him my question,
my 5 year old frame is full of scratches and dings, and is for repaint na,
what is the fastest color?
........ 888 red! ;D
if i leave it raw aluminum, do i need to clear coat it or leave it bare?
......... you clear coat it to protect from rust-oxide build up.
what if it rains hard do I use raincoat or umbrella? and aluminum rust sets in?
..........use rain coat.. buy transparent plastic rain coat from SM cut sleeves to short length then cut pants to 3/4 push pants style now go to tailor doublestitch ends, bring raincoat to signmaker ....paint your name on back of raincoat in old english letters enamel...... (shaun palmer rain gear knock-off) mahal fox! and just use glo every week to keep it shiny. commercial no to!
koya buddy last question,
I am right handed but
when i ............., i use my left hand, hehhehehe
why do "they" put their front brake on the right and the rear on the left hand brake lever,
....left lever is clutch, right is brake, right pedal is brake.....
since I do not moto, i leave my bike the way it is, any advantagious to this set up?
..............i dunno eh .. never tried it.... hehehehe ;D
last na Please.
Is downhill healthy for our spermatoa?
cauze worried for the future.. .someone should inherit my expensive dh bike. hehehehe
stealthwanderer: Ayan yung matagal ko na gusto itanong: 1 Hour ride, mabasa ng ulan o' mabasa ng pawis sa loob ng kapote. Baka kasi ako lang nageenjoy sa ulan kasi may paliguan pagdating sa trabaho, hahah.
Aug 9, 2019 11:35:30 GMT 8
anthrax76: sa ngayon, mag jacket lang ako kapag umuulan at mahangin. kasi masakit sa balat ang matulin na ulan tsaka malakas makababa ng core temperature ang wind chill.
Aug 10, 2019 22:17:32 GMT 8
anthrax76: pero kung normal na ulan, 'di naman mahangin, hanggang mabasa na lang ako ng ulan okey lang. although i minimize kung gano katagal ako exposed. anything more than an hour, medyo delikado.
Aug 10, 2019 22:21:04 GMT 8
konablack: gamit ko two-piece raincoat, dehins lang sya ideal kung may backpack ka
Aug 13, 2019 7:39:14 GMT 8
oniechan: altered poncho..dahil ng backpack..bawas ng haba sa likod at sa side..mas malamig compared sa 2-pc na raincoat....
Aug 13, 2019 11:27:45 GMT 8
anthrax76: yung poncho, ginagamit ko lang sa climb or kapag naglalakad. feeling ko saranggola ako kapag naka bike eh, ha ha.
Aug 15, 2019 23:44:25 GMT 8
anthrax76: ang weird kagabi, padyak ako pero kahit may headwind at crosswind, swabe lang. parang tailwind yung pakiramdam.
Aug 24, 2019 4:32:23 GMT 8
lefty: Na experience nyo na sir yung pagbaba mo ng mabilis sa tulay biglang may malakas na crosswind tapos umangat yung front wheel? Nangyari na sa kin once pagbaba ko ng Southpeak. Mga March yun last year, mahangin talaga around that time last year.
Aug 24, 2019 8:50:45 GMT 8
lefty: Umangat ng konti na parang tinulak ng konti pa-side. Buti na control ko at di ako sumemplang. Nangyayari ba talaga ito normally? First time ko naka-experience nun.
Aug 24, 2019 8:56:30 GMT 8
anthrax76: hmm...never pa naman umangat yung harap na gulong ko. i get pushed downwind pero never pa umangat.
Aug 24, 2019 21:10:36 GMT 8
corollafreak: wassup!!! long time no hear dito =D
Aug 27, 2019 15:06:23 GMT 8
stealthwanderer: Hello! Meron bang pumapasok around Greenhills? If so, saan kayo nagpapark ng bike?
Aug 27, 2019 17:54:27 GMT 8
anthrax76: @cf!!! uy kumusta na?
Aug 28, 2019 0:01:25 GMT 8
anthrax76: stealthwanderer, dati may parking ang bikes dun from firefly brigade, sa parking sa harap. pero ginawa na yata yun so dehins ko alam kung saan nalipat. try ko magtanong minsan kapag napasyal ako.
Aug 28, 2019 0:02:48 GMT 8
konablack: wala na yung parking spot ng firefly brigade doon
