1998 Specialized Fatboy A1 24
I’d been looking for one of these –Super cool and sells for too much on EBay –but a member contacted me that lives less than a mile away who had this frame/fork.
3/11/2011 Update:
New parts for the bike: Specialized race seat. SBC Design 4 piece chromoly handlebars, and a set of Rhyno Lite rims laced to Bulletproof midschool sealed bearing black hubs (nice.) Changed the stem cap to a Specialized one too.
*****************************************
Unlike the other Fatboys, the cruiser only came in Polished. I bought this as a hodgepodge bike from another member with no brakes and a bunch of MTB parts on it.
I’ve since added Black Specialized Stem and seat post clamp from a 2000 Specialized Hemi. I’ve kept the cushy Avenir MTB seat –it is comfy. 26.6 Kalloy seat post is stock.
I’ve added a set of Chromoly cruiser bars from a Schwinn –the OG bars would have been the nifty 4 piece Boss style bars with the Specialized S stamped into the bottoms. (Got any?) Grips are new Lock-On Specialized knock-offs for mountain bikes.
I added a black Tektro racing V-brake on the back (vs. the standard which had heavier solid brake arms), Red Animal Teflon brake cable, and a red/black Shimano DX lever.
Wheels are black Sun BFR rim on the back and Sun Rhyno Lite on front –both are double wall, 36 spoke, but the Big Fat Rim is beefier. Hubs are Bulletproof sealed hubs with stainless spokes.
I got the tires from Muphasta and they are Specialized 24x1.80 Mt. Baldy with the cool Red sidewalls.
The cranks on here are a combination; I got a sealed BB bearing and 8 spline spindle from the Hemi and added the great 180mm Specialized race cranks that I had on my blue 98.
The Sprocket is a 40t Profile Imperial, black anodized.
Pedals are Black Specialized platform pedals 9/16.
The hardest parts of this project were the small parts; this bike uses plastic ‘grommets’ to fit into the internal cable guide holes of the aluminum frame. Used by Specialized and Schwinn that I know off, I had to buy a beater bike to get these parts. The 1998 Fatboys also used steel inserts on the inside of the rear dropouts to protect the aluminum –these are almost always LONG gone. In addition, they use a chain tensioner on the outside of the rear dropouts which is narrower than anybody else’s. I got replacement inner protectors from a spare 98 Fatboy and I got tensioners from a 2000 Hemi.
