Look out! I'm at it again

Go ahead - celebrate - I hope you get sticky Champagne all over your handle bars

Oh, I didn't even think of the TV station.  I guess being only a part time Portlander, I can be excused

Katü: n diminutive of Kranky Two. (because K2 is just so last century)

It was either that or KayJay for Kranky Junior, or SoK for Son of Kranky.

See what not enough sunlight does to some people

Perhaps you could name your next steed Gazoo. If it turns out to be a great bike then it would be "The Great Gazoo"

I have over the air TV reception and the only channel I watch is 2.1 (THIS) I've seen some strange movies on that channel.

1. - Which Disc Brakes are you going to use?

2. - Will it be a ten speed or nine?

3. - So you know - ten speed triples are now possible.

With the available componentry now available - one can build a fairy light bike even if the frame set and  - huh - um - umm  - uh motor is  22 lb. lighter

OK - I've ask enough ~

Bill:
The Great Gazoo?  Wasn't he the spaceman on The Flintstones? 
I do already have thoughts for the next one.  A full suspension trail rider called C-Bee, for Crash and Bash.  (I know, I need to get out more)

Lonnie:
Disc Breaks: Probably BB7's.  They seem to be one of the best reviewed mechanicals out there, and they're quite affordable.
Gearing: I'm going with 3x9 on this one.  All my other bikes are 3x8 and I think stepping up to nine cogs will do for now. 
Can you confirm that the intermixing problems that Shimano used to have are all gone now?  I'm planning Dura-ace barcons with Deore derraileurs.  Also, have you heard anything good, or bad, about Mavic Crossride UB wheels?  Universal Cycles has them at a pretty nice price, and I though I might pick some up next time I'm down to save on shipping.

Hi, Greg- When Shimano went 9-speed, they standardized the cable pull across the range. Dura-Ace shifters work fine with Deore derailleurs.

I guess you're after these wheels:

They look OK, but the reviews aren't so hot:

Note that the Mavic wheels are about $200 for the pair. For a little less you can get a set with good Shimano hubs and snazzy red rims:

Nice choice on brakes - - - I'm in the Velocity camp when it comes to wheels - however the Crossrides should be a decent wheel for 26" roadie disc wheels. That said - I will make comment on bladed spokes of the Crossrides.

Just the fact they are bladed spokes will give you a edge on efficiency  

Seriously - it is amazing that very little spoke wind is detected from a bladed spoked wheel as long as the spokes are flying "aligned" properly.

Example - I have run my rear bladed wheel up as fast as I could on the work stand. I put my hand carefully next to the midpoint of the spokes, then moved slowly closer to the rim, then near the tire. This absolutely blew me away - hardly any wind from the spokes was detected from this high spin speed - more wind was coming from the nipples, rim and tire than the spokes - - conviced me  

Compared to a 32 spoke - there is no comparison - 32 round spoke wheels are wind turbines. I can feel wind blowing on my face just standing near the bike. A Uriel paired spoke wheel is about one third of that compared to a 32 spoke so they are vast improvements. Can't wait to get a Aero Spoke on the stand to test it comparatively.

Once again - unscientific research scores again  

So - if I were going to put wheels on your steed - I would use Urials or a 26" 32 bladed spoke Velocity AeroHeat rim on a Velocity disc hub. The deeper dish Fusion rim would be tempting however it is heavier and less lively.

Barcons will shift just fine with Deores.

The spokes on the Crossrides may be bladed, but they're FAT bladed spokes, as they're aluminum.

I've had one on the back of my Lightning for many years. No complaints. Also have a set of them on my mt bike, but don't have much use to comment on those.

[Greg M]

Thanks guys.  I just found these on closeout at Jenson.  They're the same hubs that Jeff pointed out with a Mavic 819 rim.  Any oninions?

Looks like a nice wheel set Greg.

I particularly like the performance report from this shop.

http://www.competitivecyclist.com/mountain-bikes/review-tube/UST-101---A-Lesson-in-Tubeless-Tire-Tech.1795.html     

These guys are kind of a Peter White for MTB wheels - they DON'T want them coming back bent 

Tubular - - hmm -- getting fantsy smatsy on us

Going 26" really helps out with having bullet proof wheels under your hinny.  Tire selection is pretty darn good and even getting better.

I think you have a winner.

[Greg M]

OK, time for an update.

I went ahead and ordered the UST compatible wheels from Jenson.  How could I pass up a deal like that?  My tubing is on order from Wicks, and Nova, and the Razor's Edge made stem should be here soon.
I've been drawing furiously (in pencil this time ) and erasing almost as fast, but I think I've dialed in the final geometry.  The wheelbase is 47 inches.  The top of the top tube connects to the rear triangle at 22 3/4 inches, which should give me a seat height of around 27 inches; the same as an F5 Enduro.  The forward bottom bracket lands at 33 inches, giving an approximate 6 inch difference to the seat height, which is a little more open than the 8 inches of a Giro 26.
Here's the full sized drawing.  Finished in pen, now that I'm happy with it 



And here's a 3D partial mock-up with some PVC vacuum pipe:

  It's been a week of waiting for the mailman to arrive. My steering mast and flex stem from Razor's Edge got here on Tuesday.  Funny thing; The mast is still labeled as a Burley part.  I guess Razor's Edge got a bit more from Burley than just the tooling when they bought them out.  Still, it does mean that both bikes will match   The tubing from Wicks Aircraft Supply, showed up the next day and the headtube and eccentric bottom bracket parts came in on Thursday.
  Wow, there's a whole frame's worth of parts here!
  The house we were going to do at work today wasn't ready yet, so I spent the afternoon cutting steel.  Yay!!

  Here's where I've gotten to:



  I played around with angles a bit, and freed up a bit of room on the head tube under the top tube, so now the down tube will connect nicely and strengthen up that joint:



  I've still got to cut the mitre for the front BB, make up the plates that'll hold the seat struts, cut the headtube to length, and add the idler mount.  Then it'll be ready to strip before taking it to the welder.  Hopefully I can drop it off to him sometime next week.

  I love a day when I make a lot of progress.  Now, I can hear a beer calling.
  See you later

OH YES - - - nice looking bike Greg - - I really like that you integrated the use of a recycled rear triangle into the simplicity of the over all design - simplicity - yea - right  -- how many times did you erase and redraw the design 

 Seriously - your going to have a sweet ride there - - I bet you can't wait to get it on its first ride
