What are your requirements? The Zee are heavy … the weight is in the spindle so they are still heavy when cut.
If you just tap them then you lost the strength around the pedal.
If you are not that fussed on 200g then why not square taper?
Weight wise Zee’s will save hardly anything (literally a few grams) over a UN55 and SRAM 600’s .. what you gain in the BB you lose in the spindle …
High path are reasonably priced until you add vat and P&P …. it’s much easier and quicker to just cut your own especially if they are not taking orders at the moment.
All you need is some pedal taps and a 13mm bit… assuming you own a electric drill, file and hacksaw.
Meanwhile anyone 153cm on 175’s has got to be really uncomfortable at best…. at worst they will be doing permanent damage to their hips and knees. Getting shorter cranks will transform your partners riding… they will be able to put the saddle up higher for ascents and also be able to move abo ut the bike much more easily. Long Craig pretty much dictate the position for,shorter riders which is inevitably further forwards than they want to be.
If the SRAM 155’s work then I’d go for them .. the Zee you would need thighs like an Olympic weight lifter at 153cm to benefit at all from the extra stiffness. You can get some S600’s, pedal taps and a UN55 for about t he same as the vat and p&p or high path. Once you do one set it is much much easier than you might expect.
