First pic: Surly Ogre frame kit (large), or size 20"
Velocity Blunt 35 rear wheel laced with 36 Sapim spokes. In the center is the mighty Rohloff, anodized in black. Power of understatement. Schwalbe Big Apple tires 29 X 2.35. The Velocity Blunt have a rim
opening of 35 mm, which will offer the Schwalbe tire a very good, cruiser like setting.This is a CroMo frame with horizontal dropouts, Rohloff ready.
A few more pics:
This is how the rear end looks like. The IGH will take every available slot/threaded hole/space.
This is the front end of the bike; just regular components, nothing fancy but everything of very good quality. For example, the head set is a Cane Creek series 40. The bottom bracket is a regular Shimano with external bearings.
I did not have the money to splurge on chris king or paul components. The focus is on the Rohloff. More pics coming;
Everything is coming together. Ratio is 36/16 (crank/rear sprocket) or 2.25 which is bigger than the 2.1 recommended by Rohloff. I assume everybody reading this is already aware/cognoscente of the Rohloff instructions.
This is how the bike looks now. Fully functional, Rohloff shifting through all 14 gears, bike running as smooth as butter/silk/whatever your opinion of flawless would be.
I will be updating the blog with pertinent info about this build. In a way I am glad it is over. In hindsight, it has been a great experience. Not exactly the "time of my life", but great, challenging, demanding at times. For someone who has never built a bike with an IGH. I think that one should ride a Rohloff to understand it. It is mostly automotive technology creeping into the bicycling industry. A planetary gear box as complex as your automatic transmission.
More pics with the chain line and shifter cable routing.
The bike weighs a whopping 31.6 lbs (14.33 kg.), by far the heaviest bike in my fleet. Again ,the configuration is: threaded spindle (TS), OEM2, disc brake (DB) and external gear mech.
For the time being, there is a lot of friction in the "system". I have to break it in. So far, I rode less then 50 miles on it. Although very smooth it is hard work for me pushing the pedals on this 2 wheel tractor.
Lately (Jan 2016) I added a Surly tug nut to the rear axle to prevent the rear wheel from moving forward when pedaling hard. This is a weakness of the horizontal dropouts; the rear wheel will tend to move forward in the dropouts, no matter how tight the M10 nuts are tightened on the threaded spindle.
I also replaced the wtb saddle with a Brooks B17 one.
The bike got close to 33 lbs. now
I took a trip to Pelee Island, somewhere in the middle of Lake Erie, in between Leamington, ON. and Sandusky, OH. (4/2016)
18 nautical miles from Leamington. We did the water front trail, half paved, half gravel. About 20 miles long. The vinery was closed...too early in the season.
I wonder if any Rohloff equipped bike has made it to this location
Hi there, just wondering what crankset you have used to get the correct chain line?
