In Korean it's called kyung-reun, it's difficult for me to spell it out in english.
You can see the Korean letters (the bold white ones in the green bar) on the cover of the pamphlet in the attachments.
I just got back from a trip to Korea and visited Busan and Seoul.
Busan has a velodrome and they only race on weekends, I was there on a monday... sh1t.
Same situation with The velodrome in Seoul (it's in Jamsil in the olympic park).
Even though it was a weekday and I knew there were no scheduled races, I went to check it out.
I met two guys riding up to the velodrome for training. They were both riding Corex "president" frames and using a clamp on rear brake like Tomity's got on his kalavinka. see pics.
They told me of a shop that sells track bikes. (good bike shops are impossible to find in korea)
I was stoked. It was close by and they had a few used frames for sale.
I picked up an Interpro, the only used frame in my size. It came with a sugino 75 bb and a vantage headset. I have no idea what the tubes are, but it's got tange drop outs and nice lugs. The newer Interpro frames use nagasawa lugs. That shop was well stocked for track stuff. They had nagasawa, colnago, sanrensho, corex and interpro track frames plus all the NJS parts you could ever ask for. Of all the track frames I saw at the shop, none were stamped NJS. Corex and Interpro were the only two companies that I know of that make track frames in Korea.
I cant wait to get this bike put together, I've got almost everything, I just need to get a Sugino 75 Crankset to match that bb...
let me know if you know of a good place to get one at a decent price, used is fine
