    Interloc Tempest - XC racer

    I decided to start XC racing this year, taking my existing Santa Cruz Superlight and trying to built it into a pure XC race machine. However, I couldn't get the SL under 25 lbs without spending a bunch more cash, so I decided the cheapest way to drop a couple of pounds of bike weight would be to replace the frame with something lighter. So, I went looking for sub 4 lb steel hardtail frames for $350 or less and found what I was looking for - a new 2004 IRD Tempest. Right at 4 lbs, Reynolds 853 main triangle, and under my budget!! (Gotta love ebay.) Funky, old school (or East coast) geometry (shortish top tube for the 19" frame size), and strange downtube derailleur cable routing (like a road bike), but the welds look very nice and the frame is nice and straight. Steep 71.5 head angle, but standard 73 seat angle. Here's the full build spec:

    Frame: 2004 IRD Tempest, 19", Reynolds 853 steel
    Fork: 2002 Rock Shox Duke Race (80mm travel, 3.3 lbs)
    Wheelset: XTR/517 front, XTR/618 ceramic rear (another cheap ebay find)
    Brakes/Levers: Avid SD 7 rim brakes
    Shifters/Rear Derailleur: SRAM X.9
    Cranks/BB: Truvativ Stylo Team, ISIS Gigapipe BB
    Headset: Chris King
    Post: Thomson
    Stem: Easton EA 50
    Bar: Easton Monkeylite carbon, 26.5" wide, 1.5" rise
    Saddle: Selle San Marco Aspide ti
    Tires: Hutchinson Python airlights
    Tubes: Specialized ultra-light
    Pedals: Time ATAC
    Cassette/Chain: XT 11-32, SRAM PC 99

    Build came out to somewhere between 23.5 and 24 lbs, depending on the scale. Not XC race bike light, but a lot closer than the Superlight was. My first ride impression is that for everyday, non-racing duty I'll need some beefier, grippier tires because this thing handles faster than any bike I've ever owned. Talk about quick steering!! Actually, it handles pretty well and the stiff rear end means instant power transfer to the back wheel when climbing. It could use a stiffer crankset, but that will have to wait!

    (So, anyone interested in a lightly used Superlight frame? )

    Nice. I used to ride the Breezer Lightning, which the Interloc is a current interation of. They have similar geometry and construction. The geometry is very 1990's and seems ideal for 80mm travel fork.

    They are sweet riding hardtails. Very race worthy indeed.

    You can see the Breezer lineage in the dropouts - Interloc calls them "Breeze in" dropouts, I suppose in homage to the original design. As for the ride, I'm very pleased so far - and it feels like a feather compared to my 32 lb full susser!

    Isn't that just what Joe Breeze called his dropouts? If I remember correctly, Breezer's "Breeze-in" dropouts were used by some other framebuilders, and still others just made a version of the design themselves like Moots. Anyway, I didn't know that the IRD hardtails are basically the latest Breezers after the company seemed to have disappeared for a while only to return as a commuter/city bike company a few years later.

    Ahhh a good steel hardail

    There's just something right about a good steel hardtail.

    Got my Interloc a while back. Was considering a custom Teesdale, a Gunnar and a few others at the same time, and just fell into the Interloc. Very happy with that.

    It rides great. I'd been on a full squishy before (during and after) the purchase of the Interloc, but missed the ride of a good steel bike. Something immediate and responsive about a twitchy steel bike. 71.5 degree head angle and a short top tube isn't for everyone, but perfect for mid-west XC riding.

    I've had mine for about two seasons so far, and it's a blast. It isn't the primary bike, but it is capable and like the dually keeps begging to be ridden faster.and harder than it's pilot really can.

    Enjoy the ride,

    My Ride It's gained a little weight in the past month. Swapped on some heavier tires, it lost the Next cranks for some Turbines, and got a heavier seatpost, but that's about it. So might be about 1/4 to a 1/2 pound heavier. I'll have to fix that soon too.

    From one flat land to another.

    Advocate as if your ride depends on it...

    Joe Breeze had some input on the Interlocs. Also, Interloc is also distributed by the same company that rep'd Breezer, Merry Sales Co. So many of the old Breezer shops picked up Interloc hardtail after Joe left the bike biz for awhile.

    I know what you mean - I have the 17", and I feel a little jammed up in there. It's all I've been riding for the last 3 months. I recently switched out the shock in the photo for a 80mm. Really livened up the bike.
