29er / Re: Workswell M-178 Full Suspension EBike
« on: December 12, 2018, 02:07:50 PM »
See my reply to your PM.   BTW I'd be a little leery of a frame that exists only as a rendering.   The one I built is this one: https://www.lightcarbon.com/lightcarbon-full-suspension-enduro-ebike-mountain-bike-frame_p46.html 

I can vouch for its performance.

These guys want bulk orders though, don't know if they will ship a one-off.

Any love for an Ebike?  150/150 travel F/R, 'slack' geo,  Shimano E8000 STePS, Di2 11sp, full carbon, Fox/RS Yari suspension.  Crank Bros dropper, shock remote lockout. Now on heavy wheels, 47 lbs with pedals.  Carbon wheels coming, should knock off a bit of that.

My buddy raced the FOTR last weekend, had a good time.   Now we are gearing up for the 24HOP in Feb.  The Ti bike will be the racer for that.  I hate to say it, but it has taken the place of my carbon hardtail for racing.  It is nearly as light, does not accelerate quite as fast, but the ride quality makes up for it.  I found descents very difficult on the carbon, whereas the Ti is much more controllable.  Still I needed more in that BB rock garden!

I do want to have a fast FS bike in the stable.  I have a Stumpjumper FS which is a great bike but it's a trail bike.  I like the looks of the Carbonal Titan but the biggest is 18.5 which I'm afraid is too small for me.

I came over from MTBR.  I think I saw the link in Epic_dude's sig.  I peruse the Chinese carbon thread there because I have built two chiner hardtails, one for me and one for my wife, and now as a result of that rock garden on the BB 104, I'm considering a carbon Epic-like FS XC bike.  That led me to the IP-036 builds and over here.

The titanium bike was the result of a similar process.  I was wanting a lighter frame for my Redline Monobelt singlespeed.  I designed one using BikeCAD, and read the threads on MTBR about the Chinese titanium frames.  I sent the drawing to XACD, a Chinese frame builder, and they built the frame for me.  Once I got it, I decided it was more fun as a 1x10 and built it as a standalone bike.  It is pure joy to ride. XACD did a really good job on it.

Build is X0 carbon crank with XT derailleur and XTR trail brakes. Reba dual air forks 100mm.  I built up the wheels myself using Novatec 711/712 hubs, DT Comp spokes and Light Bicycle 35mm DH carbon rims.   I'm running a MRP spiderless front cog at 30T with a 11-36 cassette.  Raceface seatpost and Kash Money bars 780mm.  XT shifter and Ergon grips, Fastrak Grid tires at 24 PSI tubeless.   Bike weighs 24 pounds without pedals.  I'm a heavy rider at 230 pounds so the frame is a little heavier to compensate.

Geo is 69.5 head angle, 73 seat angle, 65mm BB drop, 420 mm chainstays (I can adjust from 420 to 440, currently set at 430).  The bike steers quick and playfully, but is stable and the rear follows the front through turns very well.  Very happy with it.
 
Attached some pics of the Ti bike clean, and the carbon HTs I built for wife and me.

So now on to the FS bike... I think.. ;)

Hi Ken (and everyone.) I was at the BB 104 with you also.  It was my first time riding that race.   I had intended to ride the duo class but my riding partner got sick Friday, so I switched to the 104 solo.  I had no idea if I could finish the 104 miles or not. 

I was riding my Chinese custom built titanium bike (can I say titanium here?) and I finished the race in time to get a buckle.  Very proud of my little Chitanium race bike.   

That was a hard race.   Congrats on your finish!
