Token makes a 11-29 cassettte, the weight is lighter than DA. i have the IRD 11-28 on my bike w/ FSA compact 50/34. the shifting is not is smooth as Shimano's cassettes. The guy @ Professional Cycling Discount who is the Token dist. indicated that the shifting is not as smooth as Shimano's that proper lubricating was key w/ improved shift performance. has to do w/ the ramping on the cassettes. You may want to look into a compact, it has been well worth the money.
