The headset is a heavy duty FSA Pig headset from a downhill bike.  The stem is a threadless DEAN stem, a real trophy from the mid-90's with some character-giving scuffs.  The handlebar is a regular Nitto drop bar, the bar tape is Cinelli, high quality Italian with a great feel. The tape is cream colored to match the IRO logo, with the slightest peppering of a darker color.  The brake levers are road style and one has a white hood and the other a black hood, very indie.  The brakes are silver road rim brakes.  The cranks are matte black BMX cranks.  The chain is a fat-linked "Rustbuster".  The rear freewheel is a BMX freewheel.  The tires are 25C width.

This bike was built by my buddy Andres and his friend Mike.  Thanks guys.  This thing is beautiful.  Very fast, light, compliant ride.  I use if for commuting around Baltimore.

I love my Mark V.  It has Suzue Pro Max Hubs, Vredestein slicks, Sugino XD crank, 42 T Rocket Ring, 16 T cog, MKS pedals, Selle italia SLR saddle, Ultegra front "emergency brake" and a Tsunami Toro bar.  This bike is exactly what I want.  Thanks Tony.

The whole thing weighs 19lb. total. The bike rides like the bike I always wanted. It handles beautifully, feels strong and reliable, and everything fit just great with no nasty surprises when building it. I get plenty of compliments on its looks alone - even from pedestrians and SUV drivers. If only they could ride it - so NICE.

I ride it every day for at least 15 miles. The wheelset is fantastic too. Have been skidding and skipping and running over the occasional pothole. So far they still spin like butter and the rims needed no truing so far, except for the initial one. So big thank Yous to you and all the best wishes!!!

This bike is awesome. It's smooth, solid and quick. I dig it. The frame is a 53 Mark V with stock forks. It rolls on R390 Alexrims with light weight high flange hubs and Michelin Dynamic tires. It has Sugino RD 5000 cranks with a 46 ring. The gear on the hub is 17 that I got from you. It has a MKS chain and stock Giant pedals with cages. The seat is a Velo plush. It has a 120mm Dimension stem and Easton MTB riser bars cut nice and narrow. It has an Aheadset. I have a Tektro brake on the front that I try not to use but I have to say it has saved me from unexpected car doors flying open a couple of times. That's it, nice and simple, Thanks a lot for a great frame.

I am really impressed with the ride and handling of this bike.   I enjoy 44 mile commute to work on it.  I used most of the parts from another bike, mostly ultegra for brakes, brake levers and cranks.   I am very happy with this purchase.

 My bike is pretty much the standerd Mark V except I replaced the handlebars with a pair of DIY bullhorns, and put some shimano clips on there.  I really enjoy this bike and ride it as often as I can.

Drivetrain: sugino 75 cranks with sugino 75 51-tooth chainring mated to a euro-asia imports 18 tooth cog, all held together with a 1/8" wipperman track chain. The bottom bracket is a standard shimano UN71 at 110mm. It's 1mm off perfect chainline for the sugino/eai, and i've gone hundreds of miles without a problem. I have been told that the sugino bb is an excellent match, so I may up/sidegrade to that when I have a chance/cash. The pedals are basic HKS sylvan track pedals, with a metal clip and black leather straps.

Cockpit: nitto b123a chro-mo track drops wrapped with cinelli cork. Forte  cross lever mated to a POS no-name brake caliper in the front. No rear brake needed or installed. All this bolted onto the fork tube by a 90mm Thomson stem (5deg rise, flipped to 5deg drop). As you probably know, the headset is a FSA orbit. On order is a nitto b018 bullhorn handlebar.  i chopped an old set of drop bars for the home-grown bullhorn ride, and i really liked it. I figure once the nitto's get here, they'll stay on fairly permanently.

The seat post is thomson 25.4 bmx, using a 26.0 canecreek shim. It holds a Brooks Swift (in antique brown) rather too firmly i think sometimes (ti rails are soooo nice).

The hoops are velocity fusions, the front is laced 3 cross to a suzue basic high-flange track hub with DT Swiss Champion straight 14-gauge black spokes, silver nipples; the rear is laced to your (IRO's) free/fixed flip-flop hub, same DT spokes, also 3 cross. the tires are constantly changing as I'm trying to find a set that is the best balance between speed and durability. Currently I'm running continental ultra 3000 with a kevlar bead at 25mm width. They suck.  after less than 200 miles, i've had 3 flats, all from a piece of glass slicing through the center tread like it was butter, and they were at full recommended inflated pressure too! I've a set of 04 All Condition Armadillos on order from specialized (at 23mm). I've had really good luck with armadillo tires in the past on my street wheelset for my mountain bike; i'm hoping for similar luck with these.  Weirdly, I prefer the harsher, but more responsive ride from skinnier tires. If I could find a set of armadillos at 20mm, I'd probably be running those right now.

This the first Iro in Italy at Milan.
All standard: I changed only the seat and the ribbon on handle bar, wrap from outside to center.
Great Bike, Thanks Tony!
