Wheels, Tyres and Brakes / Re: Alternative to Andra 30 rims
« Last post by Andyb1 on May 17, 2026, 07:18:56 PM »Thanks George. I know very little about wheel building so useful info. I don’t know what type of spokes / nipples SJS use but I have a couple of spare wheels from another brand of bike and the axial misalignment of spokes and nipples at the rim is terrible!
The good news, however, is that while my rims do not have any stickers left on them, I am pretty sure that they are Mavic XC717s which is what Thorn used around 2006 when my bike was built. The Mavic web site gives a wear limit on the rims of 0.4mm. I have measured the dishing and it is about 0.25mm (slip gauges under a straight edge across the rim). The Mavic site also says there should be internal wear indicators (shallow holes drilled from inside the rim) that break through as wear increases. No sign of those. So I think I still have some life left in the rim(s). I think I was lucky when I bought this bike as it does appear to have had very little use even though it is 20 years old.
When / if I do need to replace the rim(s) I think the Halo rims that PH mentioned would be best as they seem very similar to the Mavics. I have Andra 30 rims on my other bike (with discs) and while I am sure they are strong, they are perhaps over strong for what I need. And certainly heavier.
I want to use the Raven in India again next winter and I now think the existing rims will be fine. I rode back to Somerset from Mid-Wales on it last week (230 miles) but I will now hang it up and use my other bike for the summer.
