Getting the SOK ready for 2010 PT2.

While in the Philly area I swung north to Abington to pick up my Bianchi SRAM SOK from Abington Wheel Wright Bike Shop or AWWBS for short.

Aside from the outside of their building being a cool shade of Bianchi Green (celeste), they have a ton to offer their mountain biking customer base. One service that stood out during my first visit with Miko, the shop's service and retail manager, is their suspension tuning services. RMT Suspensions.

I explained to Miko the issues I was having with the fork, the brakes and what I ultimately wanted to achieve with the mods I was requesting.
AWWBS works on forks and I mean works on forks. I'd say 95% of the shops I visit throughout my vast territory would send the fork to either QBP or BTI for a rebuild, not these guys. In my shop days, I would have done the work myself but being a father of two and a rep, I didn't hesitate to give the business to the LBS.


Here is a mod I did on my own time. After converting the 29r to tubeless last June, by recommendation of Marshall at Youngblood Bicycles, I down sized the rear tire from a 2.3 to a 2.1 Prowler from WTB. Lighter, faster, better rubber.


With the heavier 29r wheels (verses a traditional 26in wheel) and the fact that I'm 6'5" at 180lbs, you can never have enough braking underneath you. I upgraded the front rotor from a 160mm to a 185mm by Avid. The rear rotor is still the stock size- 160mm. New sintered pads were installed on the front and rear of the bike in addition to bleeding the lines and lubing the plungers at the cylinders. (Contaminants had entered the cylinders when I had the bike on top of the Element; during a rainy-several hour drive to Williamsburg, VA last summer.)


Here is where the magic begins. It's not fair to criticize/compare the performance of this fork when I'd been on long travel, light duty freeride bikes prior to getting this steed. None the less, with the top and bottom air chambers set to where I felt they should be according to my riding style and trial conditions, the 100mm fork dove too much under braking and couldn't keep up with high speed, baby head rocks that litter the local trails. Miko listened and delivered.

The blue wipers are a wiper/seal kit from Enduro. The stock wipers are good with preventing stiction at low speeds but potentially won't seal out the contaminants as well as the ones from Enduro. Enduro's lip sealing technology is top shelf for keeping oil in and dirt out. However, these seals are TIGHT on the stanchions. To combat this, the stanchion tubes where treated with a coating of a liquid Teflon® fluoropolymer. This polymer bonds to the aluminum tubes and make Teflon even slipperier. One application lasts about 6 months on the trails under normal_non muck riding.

The stock 5wt fork oil was removed and a combination blend of 5wt and 7wt where installed. This will reduce diving during hard braking when the PopLoc is wide open. A full dose of 7wt would be a bit too thick for my body weight and could compromise low speed dampening.



I'm still running the stock PopLoc set up for now. This lever is an open compression or closed compression selector. The fork will not have an in between compression adjustment with this type of PopLoc. Once I get some months of riding on the bike, I'll probably upgrade to the PopLoc Adjust. This system will allow me to adjust the compression of the fork for either rocky terrain or flowing/no rocks-just roots, type of trails.


Now if only the snow would go away...

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
