Brakes:
Q. What brake lever should I use with your Dual Banger Mechanical disc brake?

A. Any V-brake compatible should work. Avid FR-5 and IRD Sylvan levers are ideal, because they don't have leverage adjust.

Q. Do you make a 180/203mm rotor set for rear use?

A. No, not right now.

Cassettes

Q: Are the cassettes really compatible with Shimano and Campagnolo drivetrains?

A: Our cassettes are fully Shimano and Campagnolo, respectively, compatible. Remember that a derailleur with a longer cage and a longer chain are necessary for many configurations. And don’t expect an 11-34T 10-speed to shift quite as swiftly as a 12-21T 10-speed cassette for obvious reasons, but yes, you can expect good performance.

Q: What cage length rear derailleur is compatible with your 11-28t cassettes?

A. Short cage road derailleurs work fine even though Shimano states 27t is their cog limit.

Q: What changes must I make to my drivetrain to use a wide-range casette?

A: Typically, a longer chain and a long cage rear derailleur. For Shimano drivetrains we recommend using a mountain rear derailleur with a cage sufficently long to accommodate the big cog (but not the ’07 XTR rear derailleur, which does not have a cable adjuster). If in doubt, refer to the tech documents on the Shimano website.

Q. I am having shifting problems with your cassettes. What can I do?

A. Copy and paste our tech inquiry form into an e-mail, answer the questions and send it to us.

Q: Can I use your wide-range casettes for cyclocross?
A: Yes, of course. The cogs and carriers are plenty strong and durable for the rigors of racing in mud and rain, and the ramps will help make the shifts crisp. Again, and especially, a mountain derailleur with sufficiently long cage (though not ‘07 XTR and '08 XT) is recommended for optimal performance.

Q: Why don’t you recommend using the ’07 XTR/ '08 Deore XT rear derailleur?
A: We do not recommend pairing our cassetttes with the '07 XTR rear derailleur. The XTR derailleur lacks a barrel adjuster and we have concluded that the body flexes to the point that shifts are compromised and overall performance impaired. The XT for '08 also lacks a barrel adjuster.

Q: Can purchase individual cogs/parts of the cogset/lockring?

A: No. Complete casettes only.

Derailleurs:
Q. How do I install your CD front derailleur?

A. Our front derailleur has a similar design as Shimano and Campy front derailleurs. Before you attempt to install the front derailleur, make sure you have instructions or working knowledge of installing the chain, shifters, cables and rear derailleur. This is all one system and if one part is installed incorrectly, it will throw everything else off. We highly recommend you go to a professional bike mechanic to install or overhaul your drivetrain. That said, the Park Tool website has the most thorough derailleur installation instructions we've seen.

Frames:

Q: Where can I find touch up paint for your frames?

A. The IRD Web Store

Freewheels

Q: Why freewheels? Do people still buy freewheels?

Yes, our freewheels have been popular as these things go. It seems there are classic bicycles coming out of the woodwork needing our freewheels. A very small number, certainly, but fortunately there are a riders out there who recognize that for all the advances in cycling technology, nothing can replace the hand crafted bicycles of the past—bicycles that need freewheels.

Q: Can I disassemble your freewheels?

A: Please don’t. Our freewheels are not designed to be taken apart and doing so will void the warranty.

Rims/Wheels:

Q. What spoke tension should be used for your rims?

A. There are endless possible answers to this question...varies with the quality of the spoke, style of spoke, build configuration, how many holes in the rim, etc.


Q. What are the rider weight limits on your Cadence rims?

A. The Cadence is one of the lightest road rims available. A light rim with a light build will not last as long as a more heavily built wheel. We do not publish weight limits, because it varies with spoke style, number of spokes, build configuration, experience of the builder, and customer's ride style.

Q. What is the weight limit of your wheelsets?

A. The rider weight limit of our R1700 wheelset is about 220 lbs. This is a guideline only. If you are rider under 220 lbs. and you tend to break spokes on wheels in this weight range, then maybe you should find a more stout build.
