Make your own crown race setting tool for tapered steer fork.

A local cyclist delivered his box of parts, wheels and new frame this week. Another Campy build, third one this month and for as long as I've known this guy, that's the only group I've seen him ride. Consistency.

I start to work quickly and pull the fork off the bike in order to cut the steer tube. While the fork was sitting on the bench and realizing I do not have a crown race setting tool for a tapered steer tube, I'm taken back by the 'lawyer tabs' on this fork. They.are.huge! The old Christmas cartoon of baby New Year and his huge ears, came to mind as I marveled at their twice the normal size.

Not having a parts supplier at my disposal, I'm momentarily stunned on how I'm going to install the 1.5" bearing race. The 1 1/8" Park Tool version obviously won't slide down far enough and tapping on the race with a screwdriver is not my style. With a quick trip to the local big box hardware store, I nabbed a $4.00 section of 1 1/4" PVC tubing, with an inside diameter 1mm larger than the tapered steer tube (34mm). I used a radial arm saw to cut the tube length down to the size of my standard Park Tool crown setting shaft. This power saw will ensure the ends of the plastic pipe are cut perpendicular and set the race correctly in place; straight.

Ed Note: this method will only work for a steer tube that isn't flared, starting two inches above the fork crown- like most forks. For those you'll need the Park Tool CRS-15.

Man, this is a great story. I was surfing the web trying to find a way to install a crown race on a new set of rigid forks and ran across this article. I was getting ready to spend 70 bucks for the park tool CRS-15.

Getting the most out of your SRAM GXP bottom bracket.

This maintenance session is geared towards the SRAM GXP external bearing bottom bracket. I've been running the GXP bottom brackets since 2011 and have been really impressed by the ease of installation, and smoothness of the bearings after a few dozen rides after first installation. Bottom brackets seem to be on the love/hate list of items that cyclist have to deal with during their lifetime in sport. The 'bb' remains out of sight, out of mind until their first warm weather ride and halfway up a climb, the clicking starts, typically at the 2 o'clock position in their crank stroke. You can either endure the noise or take it to your LBS and have them deal with it which could set you back $65 for a new BB and almost that much in labor. At the end of the 2011 cyclocross season, I did my final bucket cleaning of the bike and then hung it up until the end of the winter. Around March 2012, I pulled the group off the Cavaria, minus the compact cx geared crank and swapped t

2009 Bianchi D2 Super Pista frame

There is no doubt the Pista Concept frameset is one of the most requested items from dealers nationally. The PC has developed a large amount of street cred to the point that making enough to sell has been at times tough. But, when you're given lemons, time to make lemonade right? Fortunately our UK family has the solution for us Yanks. The D2 Super Pista frame. So the million dollar question is, why this and not the Pista Concept? Well, for starters this frame is stiffer than the PC. Secondly, it is stronger than the PC. The PC is solely a track bike, or at least that is the intended purpose of it. This new frame track ready but the D2 SP frame will hold up to the rigors of non-track riding , if you get my drift. Urban use, non track use, commuting use, enough said . Yes. That is a big frame. It's celeste paint despite looking more like light blue. That's the magic of the pearl based Bianchi paint. Depending on the lighting, it will look historically celeste(green), or in b

In loving memory of Jonathan Gantz

I was looking forward to posting the bits on the Rollin's spoken word show that I saw this Friday. Instead in respect for an old friend that is no longer with us, I will tell of last Friday night sometime this week. The friend that I speak of today lost his life one year ago to this date. Jon was a fellow rider and employee of a former bicycle shop that I wrenched at. I will tell of some good memories in this post. Some are tid bits of memories that I still hold dear to my heart. I had first met Jon on a group moutainbike ride at Lake Redman circa 1994. I was on a KHS Montana Pro that I had bought that year from the shop he worked at. My first real bike, first real bike purchase, first bike with full XT and with a Rock Shox. Enough about the bike. I think Jon was about 14. I do know that he wasn't old enough to drive 'cause his dad dropped him off driving a 2wd S-10 pick up. Jon was riding a GT LTS. Some of you may remember this full suspension bike, some not. It was pr
