GCinDC's Giant DH Comp

[knoxie]

I did begin to wonder when the news said something amazing was flying through DC?? yesterday...I thought thats right Greg has got his bike back on the road? now I get it LOL!

[Sacman]

44T up front, 11T in back, but chain won't sit on that because of dropout adapter, but actually i've not really tried, so it's the second gear in the cluster, 12 or13T

Can you get away with putting a washer between the frame and the axle's shoulder? It might just be enough to move the rear derailer out far enough from the rear gear cluster so that the chain DOES sit well in the 11T.

Haha, awesome!

Greg, have you tried a rear axle mounting on the GoPro? My friend made a little bracket that attaches to the disc brake mount and makes some cool forward facing videos from this angle.

absolutely not. frame is stretched beyond comfort now. in fact, during last install, i must have dinged the disc cause it's friggin warped now... and sounds like hell.

awesome idea. can he give you a pic? will do asap (and mute sound!).

i worm clamped the gopro mount over front wheel axle this morning, but couldn't get it level. was pretty bouncy too. rear oughto to be good.

something amazing was flying through DC??

yeah, the city was abuzz about that. missed it tho.

You might want take the recommend, Get this B67 saddle and it's pretty comfortable sitting on the little wide saddle.

The peoples hyped the brooks saddle really best and very comfortable once you break in the leather (hard to soft). I am waiting for my brook saddle B73 saddle still in shipping progress and it's for my Yuba Mundo cargo ebike cuz it doesn't have suspension. Go figure.

44x12 - ouch that is small. I ride a 44x11 and above 30mph the pedal rpms are too high for casual effort. I would suggest a 53 but you prob want the ground clearance.
The jump from 12 to 11 in back is pretty big too.

Or go with an expensive Schlumpf Drive or Hammerschmidt with a 1:1.6 gear ratio crankset. You'll have no clearance or dropped chain problems with one of those.

Yep get a schlumpf - they're a bit pricey but I can pedal along at 35 mph with a 34t chain ring on the front and a 14 on the back

schlumpf

wow, 7 consonants to 1 vowel... gotta be well engineered...

installing that is not a job i'd relish, i confess. would love to have, that's for sure.

here's a go. bad music alert. lower the volume.. what was i thinking?

[Wurly]

Great videos, i love watching them, it's a guessing game as to which direction you are going next!!! left, right, up, down or sideways.
I like the music too, never heard that version of 'dazed and confused' before. Was it being played backwards?

[GCinDC]

[ambroseliao]

Ouch. That looked painful! Hope you're OK!

[hjns]

Well, at least we had a nice look at your butt.....

[Sacman]

Yeah at least you ended up with your feet on the ground and your ass up.

[GCinDC]

same vid, just bumping to top of page:

very painful.

i think what happened: there wasn't a straight run up, so i came into it leaning a bit. at the last minute, i decided to go slow, but then gunned it, but that caused me to wheelie too much.

midair i lost my balance and didn't have enough speed and room to recover on the landing. i probably wouldn't have gotten hurt at all, if it weren't for that bench. i landed hard on the edge of it on my forearm and thigh. it was a fairly sharp edge and i'm glad i hit it just with soft tissue rather than bone or joint.

during the game i suddenly noticed a golf ball sized bump popping out of my forearm!

it went down by the time i got home and is spreading out nicely. should have some good color in a couple days.

the bruise on my thigh will be as big as a personal pizza.

in other news, the temp sensor has been handy. it's so cool to see it come on with the CA when i turn on the controller (cause it's powered by halls current).

i had a nice ride home after the game, without a front light and noticed the temp was at 105C before the mile long hill. i went easy on the throttle and kept the power under 3kw continuous. perhaps because it was a cool 60F (16C), the motor only reached 112C.

interesting to note the temps elsewhere, however, via hole in motor, with one spot measuring almost 25C hotter.

makes me wonder about when HK sensor reads 150 - which it hit regularly with MC wheel - that sucker got sooo much hotter than the 26" wheel.

[etard]

Who cares about your arm, how is the bike? I saw those benches in the video and thought the same thing you did, sure enough, we were on the same wavelength...

I do like that camera angle, as a change of pace. Go nats! funny name for a team considering gnats are annoying little insects.

so the MC tire feels awesome and squishy but is TOO SLOW in a 9x7.

roll your eyes if we've been here before, but i really want to see how it will feel in the hs3540...

after breaking tools with the hookworm, i thought changing the tire was beyond my capabilities.

but when i search on motorcycle tire removal tools and saw it's just a bigger lever...


i found an old axle, tossed it in the vice, ground out two flat side, filed it down, burnt my fingers testing it, bent a little S on the end and hot damn... after prying the bead out, i stuck an bike lever in to hold it as i worked around the rim...

now i can add removing motorcycle wheels to my life experience...

someone please convince that i shouldn't reuse the same spokes.... and that i should order new ones... these aren't old you know. of course i mangled one, but can probably straighten that out... i'm talking about unlacing the 9x7 and lacing in the hs3540...

[Sacman]

Nice Greg. That DH suspension looks like it does well for just city riding. I'll bet it feels smooth and super plush. What is that front fork a Marzocchi "triple 8" Bomber?

2006 888 RC2X, in bad need of an oil change.

color is developing nicely on the leg.

i have another brand new Excel rim, that i bought before I got the prebuilt M/C wheel, so since that one is nice and true, i'm planning on lacing it. now i need to get the new hs3540...

Oil cooling FTW

[GCinDC]

Oil cooling FTW

i would load up the motor now if i could seal the existing vent holes, say with clear lexan expoxied to the inside but it would rub the windings/wires...

so i've decided to keep vented hs3540 in existing 26", which is a nice fast street version.

and i just ordered a new hs3540 and spokes for the M/C wheel build.

then i can just swap wheels from week to week depending on my mood...
