PhnomPenher
Retro Newbie
Hi recently looking at a Marin Bear Valley in Phnom Penh. Trying to work out what stem I might be able to fit. Assumed it would be 1 inch with a 22.2 stem. when I put the calipers on it it does not appear to be the case. Can anyone give advice please. Including some photos for reference, you will notice that it still has the original tyres, so I think this is a very lightly used bike.
