Well here it is after some time of ordering and building. Good things come to those who wait! Thanks goes out to John Fagone (aka NCIG) for hooking me up with the frame and Jonathan at Fort Worth Cycling for ordering various other items and building the wheels and bike. I have more pics, but these should get you started. I will post specs if people are curious. Needless to say I'm pleased with the rsukts. She weighs in at around 24.5lbs.
do you test it what is the feeling of the gate carbon drive transmission?
I've actually been too busy the last few days and it's in the low hundreds here in Texas! I'm dying to get on it. Tonight or tomorrow for sure. At the bike shop I tested the shifting a bit and it's a little rough. I heard it takes somewhere around 500 miles to break in! Once I get some miles in I'll post some ride reports.
Thanks for the compliments. Nicolai spec'd the frame with the Lefty headtube with an upcharge of I believe 330Euro and I supplied all the engineering drawings which Cannondale supplied me. I still have them if you're interested. Yes, I paid mega bucks! I have ridden it some and I have to say that the Rohloff hub isn't living up to my expectations unfortunately. I understand about the break-in period but it has been skipping/grinding which makes me uneasy. I also have had a bad first experience with tubeless technology. I started with non-tubless tires and Stan's goop and since that didn't work, I bought maxxis tubeless tires and I broke five plastic tire irons getting thim on the Stan's rims! I can't get them off now to switch back to tubes! I barely was able to put more goop in the front as it didn't hold air without the goop. Crazy. Oh well. Live and learn I guess. Other than that the bike is awesome.
Interesting, it would be handy to look at the schematics. How do you find the lefty fork? Great idea not sure on performance or servicing. Shame about the rohloff. I have always been sceptical, but convinced it was good because it was german. I am looking at gates carbon but with single speed, still trying to work out best ratio. Am torn between raw and gloss sky blue finish. As for the tubless, i went back to tubes not long ago, and so much better. On the trail i whip out the punctured tube and stick in a new one. I have not really got the trade off with tubeless yet.
The Lefty seems great. No worries with it. To be honest the trails here in Texas don't really tax it. Before this bike I was riding a custom built fully rigid magnesium frame ti front fork hardtail 17lb total bike and loving it. So, the Lefty seems fine to me. It's a light front end with an anchor rear! (but I really don't notice the weight in the rear)
you may wish to check and make sure both shifter lines are of equal length / equal tension. and the grinding should stop, also the initial break in period isntg friendly with on load shifting so you have to back off a little to shift
by the way guys, do you guys have any problem on the belt jumping teeth even the tension of the belt is collectlly assembled with the gates tension meter and a snubber assembled??
Yeah, I think I do need to check my cables and belt tension. The belt does seem a little loose and it appears the dropout adjustment may be max'ed out! Thanks for the tips. What is this 'snubber' I have heard about? Is it something that keeps the belt from slipping on the rear sprocket?
Shifter cable installation is key in a Rohloff. It'll take you a couple of hours to do it right, but it is worth it. I have now used my hub for 6 years on 4 different bikes (2 Nicolai's, 1 On One and 1 Sycip). It does get better after what seems like forever, but you will never get the snap acceleration of a Chris King, single speed (or geared for that matter) hub. The hub will also help you not go over the handlebars, though.
Having said that, if you are interested in getting rid of the hub, I'll take it off your hands. You can PM me if you want to discuss further.
>the Rohloff hub isn't living up to my expectations unfortunately. I understand about the break-in >period but it has been skipping/grinding which makes me uneasy.
This doesn't sound right. From what I understand of the way a Rohloff works it's not possible for it to skip and when I've had that problem (and sent the hub back to the factory - d'oh) it turned out to be the chain skipping over a worn sprocket. Suspect the problem in your case is the belt and not the hub.
Belt tension should be pretty high - the skipping sounds like a slack belt but if you're out of adjustment I wonder if you have the correct one. The snubber is meant to help the belt retention but I'd be surprised if that alone will sort you out. Talk to the factory on this.
They do 'grind' a bit for a while but that's your running in - it's true that they actually get better with age. I don't believe this affects drag unduly and you don't notice it off road.
Cables are important but shouldn't take long to install - I swapped some out in 15minutes or less the other day. It's important to get the length of the inners right - the measuring tube that Rohloff sell makes this a lot quicker/easier - but other than that should be fine. A mistake i made early on was to have the tension too high - don't worry about lining up the indicator numbers and try running a little slacker (you should be able to feel the click between gears - if it's too tight you cant). Personally I don't think the Rohloff inner/outer combo is that great - using other brake cable and inners seems better.

That's odd. Which tyres/rim combo are they? I gave up on non-UST tyres (waste - most beads aren't accurate enough) and now I'm running High Roller/Ignightor on Arch rims. I don't remember fitting being a problem.
