First Fixie

I'm building a fixed gear bike conversion from the ground up. This is my journey.

Things that've happened...

Had to try to adjust the seat post and that was a pain on Sunday the 23rd. Had to bring the bike to a workshop w/ a vice and clamp the seatpost into the vice with the frame upside down facing up. Then lift (really yank) the frame off the seat post. Turns out the seatpost is a 27.2mm seatpost and the seat tube takes a 27.0mm. I found this out by trying the seatpost from my Bianchi Alfana (early 90s model?) and it fit perfectly. Lo and behold that seatpost says "27.0" stamped on it. In the mean time i've sanded maybe a millimeter off the Fuji's seatpost with a power sander and it CAN come out... hopefully I'll pick up a seatpost today.

I went to the Bike Kitchen on Wednesday evening (the 26th) to get some things done and get advice. Orlando was very helpful though I got there a bit late and we worked on the bottom bracket. It definitely wasn't easy to get the lockring and cups unscrewed but we got it done. I emptied the bearings from the cups and cleaned them with new grease. Filled the cups back with new grease and put the bearings back in. Screwing the BB back on was a pain as the threads would get jammed up. Last thing I wanted was to strip the threads on the frame...

So the BB is done and I started getting a parts list. I was recommended a beginning 42t/15t ratio for starting out. I think I might give myself a little more flexibility and challenge by going to 46t/16t...

42/15 = 2.8 and 46/16 = 2.875 so it's just a LITTLE tougher, and I think 46t gives me a little more freedom and options later.

Over this past weekend I ordered a Shimano 105 front brake (used) from ebay and a Bulletproof crankset.

Parts to buy from NYC Bikes now:
Rocketring Chainring (46t)
Blue KMC Chain
Flipflop Wheelset
16 and 17t cogs
Brake Lever

Also picked up "Aircraft Remover" (paint stripper), a Mother's Billet (metal polisher), and a clearcoat spray from Pep Boys. The clearcoat is for wheels so I think it's designed to be a little more resilient to chips, etc. We'll see. Decided not to professionally powder coat as it's another $100. This is my first bike and we'll see how well it does. I 400 grit sanded some parts of the bike where the guides for the shifter/brake cables were held. Then used the metal polisher on the bare metal and it really works well. Gives a good mirror finish to it all.

I think that covers most of it! Psyched but I'm going out of town on vacation for a week. So more later...

Starting my first fixed gear...

The purpose of this blog is to document the process of converting a road bike to a fixed gear. To preface things. I don't have any real wrenching experience with bikes. I tinker with all sorts of stuff but never have done more than change a tire tube on a bicycle. Wish me luck.


Picked up a Fuji Supreme from the mid 80s (Serial No: Sl 111133) from a yard sale that I found on Craigslist last Saturday (July 22, 2006). Measured out around 58 cm. I got it cause the Fuji uses a Valite steel which is nice. The ride was really quite smooth. Horizontal dropouts for ideal Fixie conversion. The spokes are corroded, the seat was shot, and the tires' sidewall (natural rubber color) had something weirdgoing on.

Brought it home and started taking off the parts I didn't need. Seemed like a lot of Suntour and Dia-Compe parts. Brakes, pedals, cranks, derailleurs, shifters, grip tape, all came off. All this came off pretty easily with an adjustable wrench, pliers, screwdrivers, and allen wrenches.

Shown above, the brakes, shifters, grip tape, pedals, and derailleurs have all come off. I couldn't really get much further. Went to the local bike shop and got a saddle from their saddle bin to replace the gross piece of foam that came with it. Also got a crank puller and pulled of the cranks now and removed the chain rings.

More pics and details to come...
