Redline MonoCog 29er Update #2

  Here she is, a few tweaks here and there, soon she will be ready for racing. Some of the tweaks had to happen for me to be willing to enter this rig in a race. The V-brakes did not play nicely when jamming down some regular single tracks that I know like the back of my hand. Luckily the MonoCog 29er is disc ready, I installed some Shimano SLX Hydraulic brakes font and rear, very Nice braking action.

 

The stock chain snapped after mashing though a sand pit at Whiting Ranch with less than 200 miles on it. After trying to patch the chain with the help of friends and their 9 speed chain links to no avail I walked back to the truck. I got home and cut a SRAM 971 {My Favorite} chain to size, I soon realized this rear sprocket was not set up for a 9-speed chain {or 3/32″}.  It was sitting on top of the sprocket teeth.

Redline gear change
 

 I started thinking do I put a BMX chain {or 1/8″} on or a more common 9-speed chain that can be fixed with the help of geared riders if I run out of supplies on the side of the mountain. I wanted to stay with a chain that I know will last at least a 1000 miles doing SS duty. The SRAM 971 chain wasn’t going anywhere but the rear sprocket was tossed in favor of a SURLY HD 20 tooth sprocket.

When I went to change the rear sprocket I tried a new tool out, Pedro’s Trixie Fixed Gear Multi-Tool [$25.00] while shopping in the store I Goggled this tool on my phone and the first site that pops up is our friends at Bike Commuters, some more detail here   http://www.bikecommuters.com/2009/07/06/review-pedros-trixie-multi-tool/. The rear hub has a small splined free wheel with a track style lock ring that needs a hook wrench {Pedro’s Multi-Tool} to be loosened with the help of IceToolz http://www.icetoolz.com/icetoolz/index.php chain tool supplied in my toolkit.

Most recently; 50 miles on new chain and rear sprocket and no problems, lets hope for another 1000.
