Used bike build

I think that's an Echo ES3 rather than an Urban.

Don't use the IS mount, you'll crack the weld at the seatstay/dropout quite quickly. Just stick with the rim brakes.

Huh. The first I remember of the Urban was after the ES4 when Echo kinda split the ES line into two - the Pure and the Urban. The Urban followed closer to their previous geometry and overall design but got burlier with a lot more gussets, and the pure was a slightly muted version of the Koxx Levelboss with a longer front triangle. I didn't know they were using the urban name before the post-ES4 urban. Would be interested to hear from anyone who was dealing with Echo around that time.

I'd sort out a new rim ASAP... the lifetime of frames back then when people were using disk brakes was measured in months not years. They weren't designed for it, the only reason that most of them actually had disk mounts was because they were using generic mtb dropouts from a catalog.

Yeah, there was no escaping the forces and torques on the dropout, no matter how wild people got with added gussets and braces and tubes. Between better materials/hydroforming/tubeset availability/cheap FEA/much better industry knowledge, we've got it pretty good now that's for sure.

I really like those older echos. My friend has a blue urban taking up space in his garage that I borrow every now and then.

Behold, the power of trials!

Oh no!

Odd that it didn't go at the end of the gusset. Did the crack start at the bottom of the top tube?
