I have finished my first wave of updates to my pair of DT's to make them
ready for saltwater exposure this summer on our boat.
1.New Shimano UN73 Bottom Brackets.
2.New lined cable housings and new Stainless cables.
4.Replaced stem tube with alloy and added ahead stem on one bike that has bigger rider.
5. Replaced gripshift with SRAM MRX gripshift.
The only deficiency I found is something that I have experienced with other Chinese built
bearing products.... poor or little grease. Both the headset and bottom bracket had
a very light coating of a brown tar-like grease. It was not slick at all, but looks like it was designed to
stay put. I loaded up the headsets with white lithium grease.
If you are going to open up the bb anyway to relube, you might as well put in a sealed alloy
bottom bracket . You can buy one from Nashbar for $15.00. Or Shimano brand in the twenties.
The stock bb is steel with open bearings and looks like it will be corroded or worn out with much
I did have to add some tools to do the work: a Park cable cutter, a Nashbar BB tool and a Park crank puller and a used Blackburn bike repair stand.
I pulled the bottom bracket left side out by putting the bike in a vise and spinning the frame and on the fixed cup end (right side) I used Sheldon Brown's homemade bolt tool. Both methods worked fine and did not damage the original parts but I am tossing them anyway.
Everything has been standard tools and part sizes. EXCEPT... the cable housings and lengths keep you from using the precut cable kits. You need to buy cut to order, bulk or tandem/recumbent kits.
This is my very first time doing ANY maintenance work on a bike. I have not even changed a tube before.
I got my instructions from Sheldon Brown website and a book called "Bicycling Magazine's Complete
Guide to Bicycle Maintenance and Repair" I got free from the eBay seller that I purchased by bike
repair stand from.
My next wave of upgrades will come only after things break or need service with time. They will include
1.Nexus (or other) 8 speed rear hub (when hub, wheel or derailleur need work)
2. Kenda Kwest or Schwalbe Marathon tires
AND I STILL NEED A KICKSTAND FOR MY FS. PLEASE HELP IF YOU HAVE FIGURED IT OUT!!!!
