Chance to purchase a GIANT OCR3 COMPOSITE 2007 new retail $1,600.00 for $1,090.00 -still new just did not sell at this remote retail store. This is the composite OCR3- not the regular OCR3 which is a lot less.

Looking for feedback on OCR3 COMPOSITE in general and specifically the XERO XSR-3 RIMS - variable reviews.
And feedback on the TEKTRO R730 Long Reach brake calipers. I do not think these could be changed out since they are Long Reach - might that be a big deal?

The shop is 3.5 hours away so I do not want to make an uniformed decision.

Thanks in advance to all responders.
