IRD Compact Crank 46/30 assorted lengths

crank length IRD compact double:




For years we've been wanting a value-priced compact double crank that will allow for the magical 46/30 chainring combination. IRD was able to pull this off - and they are now introducing a new crank which is very similar to their popular Definant model crank This new crank uses the established 94mm bolt circle The rings are a defined pair with pins and ramps to help shifting and are 9/10sp friendly The crank is not super-light, but it is very solid and will be a great choice for countless new rando bike users The Q factor is around 152mm.  We've used this crank on our own bikes and are very pleased with it!  


The crank takes a 118mm JIS bb (not included) in theory, but we fitted one on an IRD QP-95 at 115mm and it was a nice fit (actually the chainline was off 2mm but we're ok with that).   On the 115mm bb the Q factor was closer to 148mm.  The drive side on these cranks sits about 2mm farther outboard than the non-drive (which means a 1mm offset which is trivial).. Available in 165mm, 170mm, 172.5mm, and 175mm.


Note - this crankset does not come with any crank fixing bolts - you will need to supply those we're afraid.  We like the ones that are deep with an allen head for these.  As the recess for the crankbolt sits rather deep on these, typical crankbolts like Camp will work best if tightened with a deeper socket such as the Park tool.  The Campy one doesn't go in so deep.


Note - this crank like the classic Campagnolo Nuovo Record has a sharp edge between arm and spider.  When you purchase this crank from us, we relieve this sharp edge for extra security.  Even without this sharp-edge removal, this crank is perhaps the most robust square taper crank currently in production!
