2005 Crupi Pro XL

2005 Crupi Pro XL

This is my first Crupi frame and my first set of carbon fiber forks!!!  I bought this bike used (and not in the best shape), but I'm steadily replacing parts; it's a great daily rider!

I purchased this bike on October 27, 2011 from its original owner.  The seller bought this bike in 2005 thinking that he would get into racing, but decided he didn't like it.  The bike was raced twice, and then it sat for the next five years.  It's not in the best condition (the original seat got chewed up by a dog and the forks got scratched while moving), but it's light and fast!!!  Since purchasing this bike, I've replaced the seat (Crupi Ti-Lite), seat post (Odyssey Intact), stem (Kink XXL), and brake set (Tektro V-brake/lever).  I've also added Profile bar ends, which were given to me by my little bro "Wolfman" (  The frame originally (and not too long ago) retailed for $549.99 while the forks were (and still are) about $239.99 new.
If you have any questions/comments, either send me a PM or add a comment on the discussion page.

When I get some serious free time (I don't know when this will be...), I plan to put the following components on this bike:
  * HeadsetChris King NoThreadSet (1-1/8", stainless steel baseplate - 14g, total weight = 98g, black w/ silver logo) * Headset Spacers:  Carbon fiber * Seat Post Clamp:  Profile Slim Jim (black, 31.8mm) * HubsSun Ringle Atilla The Hub (36H, 3/8", aloy axle nuts, anodized black) * Cog:  Sun Ringle(15T, chromoly, silver) * Rims:  Araya Super 7X (36H, weldedseam) * Spokes:  double-butted stainless steel spokes * Nipples:  alloy (red, maybe blue?) * Valve Caps: 8-balls (black) * Crank ArmsProfile Race (180mm, chrome plated) * SpindleProfile Titanium (5-5/8" long) * Bottom BracketProfile Euro (V2, silver cups and cone washers) * SpiderProfile (silver) * Chain Ring:  Profile (43T, black) * PedalsSun Ringle Zu-Zu (9/16" axle, sealed, black) * Chain Tensioners:  Answer (for 3/8" axles, black) * SeatCrupi Ti-Lite (black with blue trim, silver rails) * Seat PostAnswer Carbolite (26.8mm, circa 2003) * GripsAnswer Logo (4.9" long, weight = 91g/pair, durometer hardness = A/34, made in USA, feature an "Answer" logo molded into them lengthwise six times - four occurrences have filled-in lettering raised 3mm off the grip-base-surface to thicken and make the rubber surface more firm while the remaining two logos are outlines of the "Answer" logo and are left unfilled in.  The four filled in logos are to face upward when properly installed, helping to cushion against road shock while the unfilled logos provide a softer area for the finger tip to grip on the handlebars bottom side,  black)
However, if I can find some reasonable priced black Chris King hubs (for maybe $150 shipped), I'll build up a wheel set using chrome-plated 36H Araya Super 7X rims (w/ Sun Envy rim decals, if can find them), chrome-plated (or double-butted stainless steel) spokes, and red alloy nipples.  If I'm able to build these wheels, I'll also use Crupi Pro Round pedals (silver, chromoly axle) with Crupi cages (powder coated black).  I may also choose to use Profile SS High Flange Cassette hubs (36H, 3/8" 3-pc axles, aloy axle nuts, silver).
If you have any suggestions for me (for which components I should put on this bike), please give me a PM!
I currently own all of the parts listed above (except the titanium crank spindle, Chris King hubs, and spokes and nipples, which I will get once I build the wheel set).

Wanted:   3rd Gen. Profile Gas pedals;    2000 GT UltraBox chain tensioners;   20" HED carbon fiber rim (36H or 28H)
