GCinDC's Giant DH Comp

[pchen92]

keep an eye on the heat now. especially on trails and stuff. do you have a temp sensor in there? you might want to consider venting at some point. maybe it doesn't get as hot w/ 20" rims... w/o venting, and w/ all that water that hs3540 will suck up the moisture and rust!

falcon ev bag looks a good fit. i may have to reconsider that since i'm not yanking it out as much as i thought... did you cut it at all? does it flop around from side to side?

No temp sensor. It's summer here (25°C) and I haven't seen temp over 40°C on the flanges of the motor so the winding should be at 80°C max
With all the water I have been through, the motor must be rust . I tried to open it but I can't loosen the screw

Yeah I cut the foam of the bag a bit ( 6-7cm) and now it perfectly fit
Ok so I open a thread for my bike but I won't have a lot of time to work on next year

skippic came by to say goodbye, oh, and take the dh comp on a quick test drive, since he'd never ridden it before. i told him to take just 10 minutes so he came back 25 min later, the last 15 of which i was wondering what pavement he was strewn across... i know i shouldn't have worried but i can't help it!

anyway, mr skip, you said the suspension was perfect, the back wheel a bit heavy. apart from that, any comments? comparison to GT? since you're the only other person to have ridden both...

Hehe I spent 10min trying to adjust your seat, so I wouldn't fall off when accelerating. I suggest you get a couple of these:

Cheap and very comfortable.

I didn't notice that much more power on the DH (about 4.7KW max), but it might have been due to the half charged battery. The suspension on the DH is very good. Makes me think of upgrading mine - especially the rear. The brakes where much better than on the GT, but I like my brakes more. The seating position is very low, also due to your rear suspension not being adjusted to my superior weight

[GCinDC]

last thursday night, i tossed on the nobby tire, rode it somewhat cautiously in to work on the pavement on friday, but not cautiously on the way out of the parking lot:

10mph turn on a gritty-painted latex parking lot surface. good thing i had the gloves on! right shoulder, right hip, left thumb are aching, making for a fun 16hr drive moments later...

[binlagin]

I did the exact same thing. Screw knobby tires on ashpalt!

Did you damage the bike at all?

[Trackman417]

Ouch those are the worste The pain just never seems to end for the entire day, it turns into a nice ache
Neosporin helps out a lot with that kind of stuff and speeds the healing. Odds are, you didn't do any of that stuff
Hope you feel better

[GCinDC]

haha, actually the scrape was nothing - bummer i couldn't use armrest during the drive - but nothing compared to big bruise on hip and shoulder needing rotator cuff surgery...

ah well. busy weekend with family. a 12 year old fell IN LOVE with my bike, but he wasn't allowed to take it anywhere but around the house.


meanwhile, another endeavour under way:

two flashlights in ziplock, attached to gopro. but there was zero visibility down there! even w/ lights!

friggin scary actually. no tank yet, just holding breath. muck is like 3' of jelly. i swam down to it but could never touch anthing solild...

gonna try trawling from the boat with a contraption i just made:


the relatives have said the camera will be impossible to find.. but it's fun.

[GCinDC]

short exploratory ride this am:

[doc007]

good luck finding that go pro. Its gotta be there somewhere!

i see an underwater ROV and an underwater metal detector in your future

powered by waterproofed lipo packs, of course.

zero visibility at 'bottom', wherever that is. i only could feel the disgusting top levels of jelly black muck before i totally chickened out and devised a different approach:


another ride yesterday

[Hyena]

Good luck with the salvage mission. Your chances of finding it are so far beyond slim it's not funny but it's amusing the amount of time it seems you're going to spend trying to find it
I hope you have a floaty attached to it this time ?

[Skippic]

Before finding it you will find a lot of stuff you are not looking for. Consider the ratio of broken bottles and sharp rusty metal parts compared to Go Pros on the bottom of that lake...

Just to demonstrate the difficulty, try throwing a rock from the boat and finding it.

Even with scuba gear and knowing a 10 yard radius where it's located your chances would be slim.

BTW I'm getting close to figuring where your GT CA problem is.

[Thud]

HEY G-
you seem to have very little pedal clearance in that last vid ( look at 1:10) what is with you off the bike & a pedal at its low point?

good luck dredging.....may the force be with you.

[GCinDC]

good q, thud. i'll measure. not as much time as i'd hoped for stuff.

got out for a ride yesterday after we got to green bay.




picked up two tanks, so i'm planning to spend an hour under water this morning. wish me luck!

[grindz145]

Sick Greg! are you back now?

Edit: guess not (dumb phone reading comment)

[Hyena]

You get points for determination - I'll give you that much!
(both for that and your attempt to get up the hill at the end )
Looks like some pretty deep patches of water you tackled there, any flood in to the motor ?

[GCinDC]

I hope you have a floaty attached to it this time ?

last minute gorilla tape. actually worked out perfectly. also using unmodified 200lumen lights taped to wrists around surgical gloves.

can you believe i came up empty handed tho?

i had everything but a weight belt, and that proved very problematic. it was totally and absolutely disgusting, not to mention scary and unnerving. vid to come.

pretty deep patches of water you tackled there, any flood in to the motor ?

no idea. no problems... on the first run through that deep stuff, it came right up on me, i didn't even know i was gonna cross it till i was in the middle and it was a lot deeper than i expected. i heard and odd twang from i know not what. maybe a front spoke. there were big rocks under water but i figured if i kept moving...

BTW I'm getting close to figuring where your GT CA problem is.

thanks! bon voyage! good luck settling back in. i look forward to hearing about your ebike adventures in slovakia.

[grindz145]

Haha awesome!!!

[Hyena]

Yes I imagine it would be a bit scary given your previous vids of the murky depths - waiting for creatures of the deep to snatch you at any moment Maybe some CGI scaries and tense, suspensful music need to be added to the footage

on the first run through that deep stuff, it came right up on me, i didn't even know i was gonna cross it till i was in the middle and it was a lot deeper than i expected.

Heh that happened to me a while back on my hard tail - small river crossing in the middle of no where, looked less that a foot deep so I got a run up and blasted through it. I just made it to the other side but ended up wet up to my knees and I think the motor would have been completely submerged if not for the speed and the bow wave the bike created. My poorly waterproofed lipo pack on the top bar ended up wet so it was well deep!

So whats next when the scuba salvage mission doesn't recover it ? Maybe some of that sonar equipment that the cops use to find bodies in shallow graves ?

[GCinDC]

So whats next when the scuba salvage mission doesn't recover it ?

might just buy another gopro.

you know that this mission was about more than the gopro, but having put in a good faith attempt, i'm ready to quit and leave it there for the moment. unless a sonar equipped mini submarine comes up on ebay...

[GCinDC]

i'm going to bed, and we're on like dialup or something so, this won't be available for 135 min, 12:30EST (or 11:30 EndlessSphere time ), so don't waste your time clicking on it until then..

i seriously should add monsters!

oh, i dropped a rock tied to a 50' line (purple), and an anchor on the other end. i followed the boat anchor down, and then tried to crawl along 50' line but w/o weights i kept floating up...

[Sacman]

EEEEEEEEEEEWWW YEEEEAAAAKKKK... don't swallow any of that water!!!
You can't move around much or you stir up the bottom and little chunks float up and form a cloud around you.
And the flashlight beams look kinda cool but are pretty much useless in that thick and murky bottom.

Just write off that camera and get another GoPro.

[binlagin]

This is all I could think about when I saw the lights underwater!

[Trackman417]

You, my friend, have diligance
Better quit before you lose your other gopro.

[grindz145]

Holy darkness batman!

[GCinDC]

This is all I could think about when I saw the lights underwater!

nice. having a pair of those for hands would get me out of diaper duty!

we're driving home tomorrow and i had to disassemble the dredges. the more i think about it, those would have been perfect with a little more weight! maybe in combo w/ scuba?

You can't move around much or you stir up the bottom and little chunks float up and form a cloud around you.

there is no bottom. that fecal matter floating around was 4 feet above the bottom. while standing one mush with flippers, i was just above that stuff!

Just write off that camera and get another GoPro.

if you only knew what's on the SD card of that camera tho...

anyway, getting back on track. i was taking charlie to town for the mandatory sick doctor visit while vacationing... and had a half hour to burn and the yamaha dealer was closed and they were all just sitting out there so i got luca to take the photo for me.

no time to do a proper comparison now, and i normally sit more hunched than this:


the dh comp wheelbase is 46.5" compared to 53.5" for the Yamaha XT250:


also, thud, w/ no load, the pedal is 8" above the ground. when i sit on it, it's 6" off the ground...

gopro mount probably makes it look lower...
