I have two sets of airline 1's - deffo 26" mountain bike wheels. They're ok wheels if a trifle heavy. Be aware the freehub doesn't appear to be shimano so replacement when worn is proving difficult, so far. The wheel does take shimano cassette however.
BTW - think they also did airline roady wheels at one point but if yours are 26", well they're 26" and therefore ok on mtb
Unfortunately they don’t have stainless spokes so they could do with a bit of a rub with wire wool but other than that and some of the stickers are lifting slightly around the edges they are very good condition and run quite true.
I think they have been stood more than they have been used as the hub bearings are still nice and tight and I am pretty sure they have never been apart, I think this is even the original freehub grease overspill :shock: :
The rims still have the original machining / turning marks on them :shock: the discoloration on the alloy would go after a few rides worth of braking :
I have no idea what they are worth so as of yet I am not offering them for sale, I will be asking the correct questions in the correct forum soon …
