ConsHard to find online, not many sizes available
ProsMade in Japan, Sealed, quality parts, 10 year warranty
Very similar quality to a phil wood etc, it is high end and worth the money if you want a bottom bracket that will last you years and run smooth.

Hello,

Do these bottom brackets have symmetrical spindles?

Thanks.

Differences between IRD BB's 95/75/55

What are the weight, longevity and seal differences between the three square taper IRD BB's 95, 75 and 55.
Hi, the weights are 237g, 224g and 278g for the 103mm respectively. We can't comment on the longevity and there is very little information on the seals. Thanks
