say bruce, I'm taken aback offering group 2 advice to a new Surly owner but why not get a quality spoke TM? http://www.universalcycles.com/shopp...&category=2141 |

In fact I broke a couple. So I just replaced them with Wheelsmith 2.0mm spokes and nipples. But I'm left wondering what should be the proper tension in the spokes. My Park TM-1 tension meter table has a range of 17 to 28 units, or 51 to 179 kilograms, or 510 to 1790 Newtons. The tension meter says I now have about 26 units on the front spokes. On the rear it has about 27 on the drive side, and about 21 on the left side. Are these good amounts of tension for fully-loaded touring? Too tight? Too loose? Thanks for your help. spoke tension isn't determined by load but by the rim manufacturer. [nor is it determined by spoke count.] if the rims are of unknown type, you're stuck with just guesstimating based on other rims that may appear similar for which you have been able to get the tension data. and if the spoke tension you're using now proves to be excessive, the rims will crack giving you a perfect excuse to re-rim with new ones for which you /can/ get the data. ================================================== ============ The manual that came with the tension meter reinforces what you said. The rim strength determines the spoke tension. But I have no way of knowing what that is. So this is guesswork. BTW, each wheel has 36 spokes. In a moment of blinding truth it occured to me that I've got a brand new Surly LHT sitting here, so I measured its spoke tension. It is about the same as what I did. So I'm in the right ballpark. ok, good. but to be pedantic, if the surly's over-tensioned, you'll be replicating the mistake*. like others here, i think the 100kgf target is a better place to start. #26 on your gauge is 137kgf which is high relatively high. * i say that because some people are mistakenly under the impression that increasing spoke tension increases wheel strength and thus over-tension their spokes. even some manufacturers. |
