190 Kilometers for Skaters
On 8/15/2006 Derik wrote in from Germany  (193.7.nnn.nnn)

Ravn, have you ever been to the Flaeming Skate Aerea? They have around 190 kilometers tarmac for skaters: www.flaeming-skate.de
I don't know the quality of the roads, but if its skateable for inliners, it should be good for longboards as well.

rain riding
On 8/14/2006 tarin wrote in from United Kingdom  (88.212.nnn.nnn)

how do you guys cope with rain? it seems quite a few people here are in the pacific northwest, and you're bound to have a lot of rain.

my foot slipped off the front of my ldp deck last night. i caught myself so no injuries, but im not keen on it happening again. i skate in the rain a lot, even heavy rain with puddles, but im used to my old board which had a slight nose which caught my foot well when i wasnt paying attention and slipped. im guessing a toe stop would be the solution here.

another thing is grip tape. rain ruins grip tape. is there any waterproof tape out there?

i use bulldog bearing's waterproof bearings. they're not the best rolling ones, but they do the job and handle the rain well. does anyone have any other recommendations?

spare carver cx front hanger?
On 8/12/2006 Kris wrote in from United States  (69.224.nnn.nnn)

Hit a spot of soft tar in the bike lane today (happens in the summer in Sacramento a lot) and got off over the front of my LDP. I jogged it out no problem, but my board rolled into the street (of course) and got run over. Not the first board I have shot into the path of a car, but definitely the prettiest and coolest. The deck faired pretty well- chafing along the edge of the tail on the top and along right the rail edge on the bottom. Looks mostly cosmetic. Unfortunately the hanger of my front truck snapped in half. So, if anyone has a spare CX front hanger to sell, or a decent used whole front CX truck, I'm ready to buy. If not, I'll just get a new one.

For the record, I'd rather break the truck than have 2 weeks of roadrash on my palms. I'd rather have the rash than break the deck though.

Keep the hairy/ier side up.

ldp stuff
On 8/10/2006 derek wrote in from United States  (24.16.nnn.nnn)

thanks for the notes mark and stryker.
mark- imopressive reading there! sheesh- that's a lot of posts to read. james has done an amazing job of organizing his thoughts and ideas on all this ldp stuff, and getting people out for rides. he's a great resource and i continue to learn a great deal from him. same with erin- she's got tons of wisdom to offer. it's awesome that there is so much stuff to learn here, and much of it goes far beyond skateboards.

and john- glad to hear your ldp setup is ready to ROCK. my family is heading up to the san juans tomorrow, so i can only ride tomorrow morning and not saturday. (not to whine, but it's kind of a bittersweet deal, since we'll be in the middle of paradise, but on a tiny island (1/2 mile perimeter)without a speck of pavement.)
if you can get out tomorrow, i can ride until about 8:30 am, at the velodrome or crossroads. i can leave you my gps watch if you want to use it for the week to clock some times up on the centennial trail.
my # is 206 498 3386.

bolt size
On 8/9/2006 mark wrote in from United States  (68.28.nnn.nnn)

wow, read all 1700+ posts here. amazing stuff guys! I have a Roe LDP on the way. :)

I believe standard bolts are 10/32. Khiro sells a kit of different length hardware. the bolts are 10/32.

Wanna say thanks to James, Erin, Derek, and everyone else for this treasure chest of information. everyone here has given me lots of inspiration to lengthen the boarding portion of my commute, and spend lots of money! :)

toe stop pix
On 8/9/2006 peters wrote in from United States  (172.194.nnn.nnn)



I used a couple big toe-brakes off rollerskates instead of big bushings. Usually a two-bushing combo works great as well, like a couple old Indy bushings stacked on top of each other. I just put a long bolt up through the front truck hole then a washer and nut on top of the bushing. Which bolt hole you use completely depends on your front foot stance, just look down where your foot sits normally when you're at a comfortable pump. Sometimes I even have to drill a new hole in the middle of the standard truck holes.

Don't toestop believin'
On 8/8/2006 Adam wrote in from United States  (198.144.nnn.nnn)

I've made very effective toe stops with two old truck bushings in a stacked config: one barrel shaped bushing on bottom, and a conical bushing positioned small-end-down, on top. Then a quarter-sized washer to top it all off.

The conical bushing's angle holds my shoe edge quite well. I used an extra long 8-32 screw but I don't think that is heavy duty enough for LD pumping as the screw is under a lot of force and will likely fatigue at some point.. probably at the worst possible moment. If I were to build another I'd move up to a #10 screw and hope I didn't have to bore out my truck holes (too much).

So, to make a toestop, can I just use a 3" bolt, a bushing and a washer? Any suggestions?

...con colitas de borrego...
On 8/4/2006 Kris wrote in from United States  (71.128.nnn.nnn)

Couldnt get a good set-up with the Khiros. The bottom bushing blew out on the baseplate very quickly. Really need a conical bottom bushing, or a cup washer that will hold a fat cylinder bushing. I have a set of Bones Hardcore soft on there now, but I dont like the plastic capped bushings for pumping. Actually, the longer kingpin with the stock bushing would probably be the best fix...I will keep working on it.

lonerider- I took the job in Oakland and will be commuting from Sac. I will probably stay overnight with my brother in SF on occasion. I'd be up to skate after work sometime.

Brooklyn Sesssions for MJ & more on SDP
On 8/4/2006 lonerider wrote in from United States  (65.249.nnn.nnn)

I'm in California, but I just read about weekly sessions organized by Earthwing Skateboards at Prospect Park in your backyard - check it out (http://www.earthwingskateboards.com/events.html) and here for photos of the last sessions (http://www.earthwingskateboards.com/blog/).

Yea, those photos are out of date, it is now all freshly paved black pavement as they just did it this fall (http://www.svbcbikes.org/crank/oct-nov-05/index.php) is amore recent photo. Hmmm.. I'm using 70mm ZZ right now, and was thinking about upgrading to their Gumball equivalents to give me more roll speed. I don't think going from 77a to 80a or even 83a would change the grip that much for pumping.

Kris, nice work on the bushing investigation, you might want to check out Clear Radikal bushings as well. Also maybe consider getting longer kingpins (I've done that to virtually all of my trucks).

bush doctor
On 8/4/2006 Kris wrote in from United States  (69.105.nnn.nnn)

Just wanted to post that I went on a hunch and switched out the stock bushings on the front cx truck with Khiro white barrel bushings...the result was the exact feel I was looking for. The power and speed I had with my previous set-up is back. The stock bushings were too tall for me to get them loose enough on the kingpin. The Khiro's are shorter, and I think they're softer too. Funny, my original thoughts about what was slowing me down were totally off base...imagine that! Now, the only problem is that the big lower bushing doesn't seat well on the baseplate. It's too big for the carver cup washer. I tried with a flat washer, but the washer was also too small and ended up buried in the bushing. Once I get this sorted out, it will be ON!

san tomas aquino trail
On 8/4/2006 derek wrote in from United States  (24.16.nnn.nnn)

beautiful scenery there! but that trail looks a little rough in the pics ;)

i've thought about going with a harder durometer, but last week i had a nasty little wipeout where i pumped hard into the board, pushing it out with both feet, and it never came back- just slipped right out from under me. it may have been the pavement, but it was enough to freak me out for a while...

Starting out
On 8/3/2006 lonerider wrote in from United States  (71.138.nnn.nnn)

Well, it will be a few weeks before I get a LDP setup, but that doesn't mean I can pump on my 30" slalom in the meantime. After work, tonight I believe I did a very mellow 5.6 mile pumping loop in about 30 minutes. I did the San Tomas Aquino Trail from mile 1.0 to 3.8 (hopefully that link work). Normally I jog that (I always thought was was only like 3 miles... oh well). That was about the distance I like to go currently, maybe a little bit longer and a bit faster. Always awesome to try out new things! Does anyone plan on switching to harder duro Retro Gumballs if they ever come out?

contact...is the answer, it's the reason- why everything happens...
On 8/3/2006 Kris wrote in from United States  (69.239.nnn.nnn)

The WB on my 48" board is roughly 34". I have tried both wheelbases on the LDP, and I prefer the inner holes. The effect on the flex is subtle and right on target. I have also dropped down to 155lbs (and falling) which seems to tune me into the board. I'd be interested in trying the stiff flex if it's possible and not too much trouble, but I think medium is working out in the long run. I think my continuing issues are with the front truck (I have some ideas) and also getting used to pumping a shorter wheelbase than before.

I've carried my laptop in a laptop bag while pumping along- awkward but do-able. I wear a hydration backpack occasionally. It is pretty small and braces well at the chest and waist. I've also been known to pump while carrying a 12-pack of bottles, but it's a different pump altogether, no forward arm swing at all.

No mp3 player yet... my musical library is fairly extensive, but my mental music library is vast.

ms skate trail update
On 8/2/2006 derek wrote in from United States  (24.16.nnn.nnn)

great news for anyone interested in riding in the ms skate in seattle...
there's a section of the sammamish river trail that is just now finishing up with a fresh repaving job. i was out on it yesterday, dodging the trucks and the road machinery as they completed the job. it looks like they are expanding the width a little as well. the new pavement starts right next to the redhook brewery, and extends into redmond.
the ms skate starts on the burke gilman trail and ends on the sammamish trail, so it's looking like a nice smooth finish for the final 13 miles or so... come out for this ride if you can- it should be a blast!

Stiff Flex LDP
On 8/1/2006 lonerider wrote in from United States  (65.249.nnn.nnn)

Well I'm currently pumping a flexier (requested flexier for a 150 lbs person) Insect Sidewinder 30" with a 21" WB (http://insectskateboards.com/boards.html#sidewinder) with RTX/RTS trucks and Radikal bushings. You can see the shape to more like that of a Crossfire, but a little bit narrower.

I notice that my front front is directly over the front truck and I'm leveraging the wider nose of the Sidewinder to initiate the pump, my back foot is in front of the back truck. From what you've said it sounds like because of my front foot placement, the LDP is more that style, correct? Although what's you definition of "in the long run"? 5 miles? 10 miles? or 20 miles?

What would happen if I got the stiffer flex - it seems like I don't use the flex of my board as much for the initiate front foot pump. Do I need much flex then? It sounds like torsion rigidity is more important than longitudinal rigidity (common property amoung snowboards). Thanks for all the help!

packin a purse
On 8/1/2006 peters wrote in from United States  (64.236.nnn.nnn)

the 'man purse' was an inside joke with this guy Dycus that also pointed out that our sport-o lycra shirts accentuate our 'man boobs.' At least we're not wearing Chaput wiggle suits... yet ;-) With the STP distance more luggage was needed, so I wore two fanny packs, that worked out nice without throwin the pump off. And yeah Ravn I also think holding a bottle in the leading hand adds to the subtle pendulum effect as well!

Kris Tarin and lonerider, at 150-160 lbs sounds like you're on the high end of the medium / low end of the stiff flex scale for the Roe deck. I'm around 165-170 and typically stay with stiff flex, though I ride my medium when I'm cruising and not trying to make fastest times. The medium I commuted on for a solid 2 months, its really preference. Considering the shipping/distance if you guys wanted to try stiffs we could work something out, one of my friends sold the medium to a friend to get the light flex, talk about flexy! I'm curious what the wheelbase was on your 48" deck Kris, have you tried the inner holes on the ldp?

The difference with the Crossfire3.8 is mostly that the shape lends itself toward a center stance, and the default wheelbases are shorter (although you could always drill the LDP if you're confident doing that.) It makes the deck more versatile for carving, quick turn commuting, and pumping up hills a little quicker, although I still think that having the 28-29" range wheelbase with a longer stride/cadence will have more potential for flatland speeds in the long run.

Crossfire 3.8 vs Roe LDP
On 7/31/2006 lonerider wrote in from United States  (65.249.nnn.nnn)

Been reading the last set of posts, so would the CrossFire have a higher max pump speed than the LDP model? (for uphill as well) Or does it just take some time to get used to the LDP + Carver setup like Kris is seeing now. I'm 150 lbs, should I be going for the medium or stiff flex in the LDP model? Hey Kris, do you ever come down to the Bay Area to skate?

Re: carrying
On 7/31/2006 Ravn wrote in from Germany  (195.37.nnn.nnn)

tarin,
I also like to have a bottle of water in my leading hand. I guess it has to do with having some mass farther from your center of turning to generate torque. I really don't like to have anything around my hips or back. It's only dead weight. I sometimes carry a fanny pack like thingy across my back though.
