Here’s an '84 610 I built up back in high school. Don’t remember much about it but I didn’t like it very much and sold it pretty fast. Looked nice though

Official debut of new paint job

needs leopard bartape

Was at the shop buying black microtex v sorry

Would love someone to make a leopard xpac that I can make a new bag from…

What did you end up doing for chainrings?

spaghetti · January 8, 2021, 11:06pm

Nothing yet, currently probably get one of those 46/30 bikinGreen things in the spring when the full drivetrain overhaul happens

But honestly who knows. I’m known to Yolo

hey do any of you engineering nerds want to help a guy figure out a measurement based on the given information?
specifically looking for headtube length, and assume it could be… triangulated? this part of math isn’t necessarily my strong suit so maybe im wrong.

euclid · February 21, 2021, 8:54pm

I think you would need fork a-c or down tube angle to be able to define the bottom point of the head tube

earwig · February 21, 2021, 9:35pm

Yeah, in spite of bikes being “all triangles,” they’re not actually. Old geo charts tend to be under-specified so that you can’t solve for all the other angles and lengths. I’ve seen speculation before that it was intentional to keep bike geometries from being copied easily, or it may just be marketing folks not humoring bike nerds.

this all makes sense and feels very duh in retrospect

jimmythefly · February 21, 2021, 10:39pm

Also assumes the top tube is level, which isn’t always so, especially in tiny sizes. If you need accurate head tube length best bet other than measuring is to find someone who owns that exact bike and ask them to measure.

Was available on eBay locally, local pickup only and listed as a 24” (the black trek is 24”)
I trusted my instinct on assuming the actual sizing based on his shitty pictures. Told in message is was close to NOS. Threw a very low offer ~60% asking price, accepted and now 12 hours later The Angel has a new bike that fits like a glove.

Definitely not “close to NOS” but genuinely one of the best condition 420s I’ve come across

Gonna remove rear rack, swap saddle, pedals and bar tape, and will probably run the rest as is for awhile. Eventually probably cobble together an apex group on it (which I already have most of)

420 nice

karl_dandleton · March 28, 2021, 6:25pm

i worked on a probably same year 420 but it was black and green. love love love the blaze group on the 420

spaghetti · March 28, 2021, 6:27pm

You’ll all be happy to know that somehow I’m not the most excited person in the house about the 420 blaze trek

jimmythefly · March 28, 2021, 11:04pm

Hard anno rims look so good!

spaghetti · March 28, 2021, 11:06pm

yeah i love them!
whats the move here? fenders and 28s?

Bootus · March 28, 2021, 11:09pm

If your roommate wants something supple, I have a brand new set of black 27mm Open Pavé you can have for cheap.
