BLK MRKT Redux

September 5th, 2009 · No Comments · Dirt Jumper

After upgrading the crankset, I took the opportunity to step it up and redo a lot more… I changed a lot of parts this time around and the bike has a much different feel now.

It started with a few more orders from Deity. I got the same front sprocket I had again in anticipation for the new rear wheel and chain. I had a BLK MRKT Bada Bing! handlebar before, but it was cut slightly too short for my taste so I went with a Deity Twenty14. The Deity Grips are just for good measure.

Next, to be more street-oriented, I switched out the standard rail system seat and post with a Pivotal setup.

My rear stock Avid BB7 rotor was slightly out of true, so I moved up to a Hayes V6 rotor:

I was never too content with the Marzocchi DJ3 fork I had before… especially the fact that it weight over 7lbs. I decided to go with a RockShox Revelation All-Mountain fork, in my opinion a good medium between durability and lightness. I immediately had it opened up and spacers installed to lower the travel length from the stock 140mm down to 90mm. It was quite a challenge finding the necessary spacers, but luckily Home Depot happened to have some Nylon spacers that were exactly the necessary size.

I had a new wheelset built as well. This one took over 5 weeks of waiting to finally get it built and delivered, but I’m very happy with them. They’re Mavic 721 rims laced to Profile SS rear hub and 20mm Discless front hub with Sapim Double-Butted Spokes.

Of course, not everything is entirely easy. Being that the rear hub was a Single Speed, it had almost no adjustment in terms of cog spacing. I noticed the chainline was off, and it was because the front sprocket wasn’t completely true so it wobbled and thus throwing it off. A local bike shop did some filing on the drive arm and added some washers to true out the wheel, and I got a small 1mm spacer for the rear cog to get the chainline just right.

I had to run the rear cog backwards, however, to achieve this. This meant the chain would hit the lockring and skip, so I dremeled in grooves where the chain hits to make everything compatible.
