The rims on my old bike are pretty darn near the end of their service life - 18 years and 10 000 kms later. I want to switch them over before something goes terrible wrong and I'm stuck with a buted wheel.
The hubs I have are currently fine (I service them well) so all that I need to do is get a new set of rims, and reuse the spokes (which are also in good condition). Problem is that my rims are 36H araya px-35s.... which they stopped making quite a number of years ago. The E.R.D for this set of rims is 614.0mm. I've located the Rhyno Lite rims at my LBS for $30 a pop, so they look good as replacements, BUT with an ERD of 612.0mm.
So, is this a doable (read *workable*, not *perfect*) replacement? Does a 2 mm difference make or break? If it helps, I've got visible threads on the spokes above each of the nipples with the current rims, so my thinking is that this could take up the slack.
