My Bike(s) are no exception to this rule. If anything, they have given me a huge media to explore... and let's be honest, if there is anything triathletes love, it's new toys. Some have been great, some not so great, a couple of big wastes of time and money, and just a few that are downright dangerous. I'm going to go over some of them here, with my thoughts on how it all turned out. We'll start with the easy stuff first!
Carbon Crank Cover |
This was a fairly easy one, it cost about $60 give or take (depending on what you already have in the garage) and it looks great installed. You'll need the sheets of carbon fiber (I suppose fiberglass would also work) which are available on ebay, some epoxy (for composites) and some plastic wrap. Take the crank you want a cover for, cover it with the plastic wrap, and lay the carbon (carbon, epoxy, carbon, epoxy) and allow it to cure. Then cut away the extra carbon and drill/dremel holes for the crank bolts. You can skip the holes if you don't mind glueing / epoxying the edges of the cover to your chainrings. I was personally a bit worried that I'd get reprimanded at a race for a "fairing" so I never epoxied mine. It's now sitting in the corner of my garage. It's also kind of a toss up as to whether or not this "mod" would actually DO anything (in terms of actual performance gains) as there has been some debate as to whether covering the crank is helpful. Nonetheless, it looks really cool.
Chopped straps |
"Oversized" 13t/15t wheels |
David Millar's setup |
I sourced one on ebay (from a foreign seller) and when it arrived I met problem #1... that is, Shimano does not want you taking their beloved derailleurs apart. Oh sure, you can unscrew the cage, and then "BAM" the loaded spring shoots parts everywhere! Finding everything is the easy part, now you have to put it back together. Let me say, it's going to take some seriously manly hands to get the tension back on the spring AND get the screw set in the back of the cage. It took me 3 hours spread across two days, a couple of beers and an extremely sore hand before I finally got it.
Then there's the other problem... the chain. If you look at Millar's setup you can see the stretch that the derailleur is under. Trying this for yourself, you are going to run into a no-win situation. On the one hand, you lengthen the chain... at which point you are going to have too much slack in certain (bigger) gears. On the other, you shorten the chain, and completely lose the ability to shift into your top 4 or so cogs in the big ring. (Not that you should be in them anyways.) Which is not ideal. Also, the custom plate I bought had just a little space in the "nob" that keeps the chain from skipping off... when I would go from big to small ring it would sometimes *catch* for just a second. It never did any damage, but it always worried me, and eventually I took it off and returned to the good old fashioned way. As far as performance goes... I never noticed anything, but there were never any claims that it would make some huge jump anyways... I'd skip this one unless you just love the look (it did look cool)
DT Shifters |
Well, from ebay actually... but I digress. There are 7800 Dura Ace downtube shifters (they still make em!) mounted to the plugs from regular 7800 bar end shifters. (You will need to cannibalize some bar end shifters to make this work btw) These guys give you a lot more leverage to shift in aero (or they do me at least) and they look really cool. They are a bit longer than regular bar ends, so you may need to trim your bar length to make up for it. I still use these and love them.
Custom Mount |
"Cobb Hack" front Brake |
David Millar's 1/2 Hack |
This is the dangerous one. Let me put this one out there up front... the cobb hack WILL NOT stop you reliably! Do this mod at your own risk! (Seriously, I'm warning you, don't come crying to me when it fails at the worst possible moment) That said...
... So you want an aero brake, but don't have the cash to drop on an Omega / Simkins / Hooker / whatever. Well, this is an old trick from Mr. Cobb. You are only going to be out the cost of your brake if (when?) you screw it up. The first step is to cut the top arm (as in David Millars pic above) and drill a new hole for the cable to run through. On mine I started with a wider hole (enough for housing to sit in) and then made it shallower out the other end. (just wide enough for the cable itself)
-------If you stop at this point-------
You can still stop the bike reliably. What you're essentially doing here (that you care about) is making it a little easier to route your front brake cable housing "cleanly." (like a center pull aero brake would basically) Besides having to replace the cable a bit more often, you shouldn't have any negative side effects.
-------If you keep going-------
You will cut the other arm off as well (right past the point that holds the cable) and then drill and tap a new hole through the side of what's left of the arm. Now, obviously you need to make SURE you tap it right. Then, find the right screw and shave just a tiny nub into it (where the cable will fit when it's secured) and then red loctite the crap out of it. shave another nub into the brake arm (very slight, you want the cable to sit there, not fly out) and say a prayer to whatever god you see fit to ask mercy from.
I used the full mod for one Time Trial. That was enough for me. I'd rate stopping power somewhere around that of a poorly adjusted Modolo Kronos / Delta Brake (that is, nonexistent) Afterwards, on a training ride, the cable stripped the threads out of the tapped hole (not sure why to this day)
Those are just a few of the more *interesting* things I've played around with. I'm currently playing with creating my own carbon parts, which is a bit more expensive (and time consuming) than most of these things. Updates will come at some point, if I ever craft anything worth showing off!
Until then, keep tuning!
