...I am glad to hear that Merlin's QC has gotten better, though I am skeptical that the Merlin Magia has the HIGHEST tolarances and quality in the industry. I was an loyal Merlin customer up until 2001 when I tried on three separate occasions to purchase a new Merlin Extralight from Excel Sports, but each frame was defective in one or more ways. I was so dismayed that I sent a letter to Mark Lynskey on September 26th, 2001 that apparently did have an impact as I heard from Excel Sports and Tom Kellogg.

You are right, William R-O-C-K-S. I have dealt with him and he is one of the most professional individuals I have encountered. Also, he does one of the best, if not THE best, packaging jobs in the industry.

As weight weenies we want the lightest, strongest and most efficient of everything. A small company comes out with a product that breaks all barriers of lightness and offers far superior braking to anything available. They don't have a huge budget for R & D and to get to that weight they have to make some compromises. They work to high high level with their existing customer base FedExing( Read expensive) what ever is required to make the product work for you the customer. Plus answer many phone calls ans emails. I have two sets of the Zero G brakes and the first one I had an installation issue and Zero Gravity worked it out for me. The second I have a problem also and they are machining a spacer for me. What else coould I ask for? Would Shimano, Sram or Campagnolo do this for me?

William from Wisecyclebuys has always been great to work with. He on many occasions assured me if I didn't like a product I could send it back and he would issue me a full refund. I've done it and he did. I had an issue with a fork and he shipped me a new fork and I had it befiore I had even removed the other fork from my bike. He didn't even ask for a credit card number or for me to Paypal him the funds to pay for the fork. He sent it and assumed that I would send him the other fork. Try getting Excelsports, Performancebike, Coloradocyclist or Bike Nashbar to send you a replacement for a defective part and not charging you for it. They will send it, you will pay for it, the refund will come sometime after they receive the item back.

Both Zero Gravity and Wisecyclebuys are providing a value added service to us working with the knowledge and resources they have. I will continue to support them both know that they support me in my effort to have a very light weight and reliable bike to ride and compete on.

A big thank you to William and Zero Gravity. You guys Rock!
RESIDENT GRUMPY OLD MAN.

With Campagnolo and Shimano you wouldn't have the spacer problem to begin with. Also, I'm rather puzzled by your statement that ZG brakes offer superior braking performance to anything available.

Zero G's generate more clamping force then any other brakes calipers in existence, hence superior braking power to anything. :D

Highest clamping force isn't directly related to good braking. Neither do ZG have the highest clamping force for that matter. Not saying the ZG don't brake okay. Just not the best.

Zero G's were tested to have the highest clamping force, so what are you talking about?

Higher clamping force with same pads in a test means superior braking power.

Superlite, divve say something about the relation of braking powers to what makes a brake good. I agree with him on the fact that clamping force is only one of the things that makes a good brake.
If braking power was everything, every bike (at least every MTB's would have Downhill Brembo or hope diskbrakes (but since these brakes generate so much power they are no suited for anything but downhill)

Tested by whom? Certainly not the numbers I've seen and actual use shows this.

Highest clamping force doesn't indicate anything about the power curve of that force. It could simply mean on and off with nothing in between.

Superlight, if the test you mentioned is available on-line, would you please list the URL? I am interested not only in the force generated by ZG's, but also if Campy and Shimano would be listed. I have always wondered how the big 2 stack up against each other.
Thank you.

If you do a test with different brakes, all with the same pad compound the brakes generating the highest clamping force is going to slow down the wheel faster then the others, what don't you guys get about that? Were not talking about a car with different diameter rotors, rotor thicknesses, vented or solid discs, 4 piston calipers or what ever.

In something like a bicycle road brake caliper the only things that are going to show braking power are related to pad compound, clamping force, and rim surface. You put a control test in place so the rim and pad compound are the same the only variable left is the clamping force. More force, more stopping power. Pretty simple.

Honda, the test was done by Zero G, they have about %6 more stopping power then DA 7800.

Yeah...here's another good one for you.....and with two equal wheel builds, the one with the highest spoke tension will be the stiffest.

Sarcasim isn't your strong suit. :lol:
