I've read that you can make a lever similar to the Paul Cross Lever using a standard MTB lever. But I cant figure how you would route the cable. Any help appreciated.

There's a thread buried down from about 6 months ago, but here's how I did mine. Keep in mind that the function is essentially the same as if you were to grab the cable along the top tube and pull. The tension will feel the same on both pairs of levers. I find that on really ugly singletrack the bike is much less twitchy when I'm on the top levers.

1. Scrounge up some BMX or old canti levers. NOTE: they will be too small to fully clamp around the bulge (or the regular part also) of the drop bars. Plan on either grinding away with your dremel or just drilling a through-bolt after they are in place.

2. The cable will leave your drop lever, run along the bar, then come out of the bar tape and go into the back of the canti lever (not the perch). I drilled a small hole for the cable and a larger partial depth hole for a stepped ferrule. The cable will run through the lever and exit through the barrel adjuster on the perch.

3. You'll have to play around some to get a clean path for the cable through the lever and perch ass'y. Also, at this point you can decide either to keep the barrel adjusters on the perches or use inline adjusters.

4. After you get them at the right angle for your grip (assuming they really don't fit the bars), use a c-clamp to press then in place. Drill through the original bolt hole through the top of the perch (not through the bar, duh). Counter sink the hole on the top to fit a new allen bolt, then pop it through and put a nut on the back.

The first lever takes a while to futz with, and the hard part is figuring out how to reduce the friction in the bartop levers so the drop levers have no play. Cranking up the spring on the brakes may help, or use some inner wire tubing inside the lever routing may help.

Paul's levers look sweet, and if I had the spare $70 I'd do it in a heartbeat. Mine are dinged up old Dia-Compes and cost me $5, a few ferrules, and 3 or 4 beers.

Good Luck!

Unless you're really broke, have a dremel tool and a pair of old brake levers you're better off just buying a pair of cross levers. IRD/Merry Sales now make a set that are a near perfect copy of the SRP levers. They're made in Taiwan and retail for $40-50/pair. Just as good as the SRP or Paul levers.
