I agree with you, up to a point. The bike has not been pampered. It looked like they'd repeatedly oiled the chain with motor oil. There was dried caked greasy dirt on the chain and up to 3/8" thick on the rings. I went at this with brake cleaner and a toothbrush. The bike was already covered with this grit; I added to it before blasting it at the car wash. It still needs a good cleaning/detail, which I won't do if I don't end up keeping it. It already looks far better than it did when I got it.

The paint on the frame is bumped and scraped and the decals are not the best, either. If I do keep it, it will be a bit of a rat rod, as I'm not going to have it stripped and repainted. I will stamp out the little bit of rust it has and do some touch up.

The more I look at it, the less original it looks to me. It has a sleek Italian saddle, although not a high end one. Are these the original rims? IDK...


I like the tires that are on it. As I was closing the garage today, I swear the white walls were reflective. That's awesome. There's something about this bike that I really like. But I am more concerned with having it be functional than doing a complete restoration. I am a do no harm type, though...

Not every bike is destined for a re-birth as new. If it were mine, I would tear it down and put in some elbow grease. You'd be surprised what a thorough cleaning, a magic eraser, and some rubbing compound will do. Touch up the white paint (easy to match), re-grease all the bearings and put it all back together. Roll with the triple and the wider tires, dial in the canti brakes, and you have a path, gravel, road bike for as long as you want it. The eye focus on the cool graphics will hide a lot of sins. Update along the way if the mood strikes.

100%! This is exactly how I feel about it.
Have you done bearings? I was thinking that I'd want that done too, but was wondering if I should attempt it myself. Are there torque specs?

If you're going to overhaul the hubs and bottom bracket, the specialized tools (without which you cannot do the job at all so don't even try just buy the danged tools) will cost you way less than the labor. It's an easy but slow job, and when you're paying by the hour, it ends up costing a whole lot. If you have the correct bicycle-bearing-specific tools, it's not difficult, just a bit fiddly and slow the first few times you do it. If you don't, it's an impossible nightmare. Buy the tools. There are no good substitutes for bicycle cone wrenches, headset wrenches, and bottom bracket tools. Yes, they're way more expensive than they should be. That's because literally nothing else works.

No, there's no torque specs for bearing cones that I'm aware of, and I wouldn't trust them if they existed, because circumstances alter cases. You adjust them by feel, and the differences between "too tight", "too loose", and "ahhh..perfect!" are not subtle. Just play with it, and you'll figure it out pretty quickly. Plus, it's almost impossible to do permanent damage to cup and cone bearings on the repair stand. It's possible, sure... but you'd have to really be trying to screw things up. (Like using a cheater bar or an impact gun or something.) It's riding them maladjusted, dry, and dirty that makes them die.

Working on bikes isn't really that hard. It's the weird incompatibilities and 14 competing standards for everything that will trip you up. The actual turning-the-wrenches part is pretty straightforward. (As long as you have the tools. Buy the tools.)

Dang Shannon, that's hugely helpful. Do you have any suggestions for a good book or video(s) you have found particularly helpful?

Here are photos of the retention clip. Should the groove be there? I'm guessing this wear is abnormal and cutting the cable as it pulls through? What do you think?

the traditional neurosurgeon method of sawing through a skull was to use a diamond coated cable.
Something is amiss. adding some purchase to the cable- looping about the bolt will add surface area and assist, but there is plenty there to diagnose before reattaching the cable.

Others might cringe, but RJ is not a bad source...the Park videos often are more modern stuff, but are also excellent.

Overhauling Bearings can be therapeutic...and once you have tools, are simply the cost of grease.

The tools will pay for themselves pretty quickly.

you might want to post a WTB and list tools. You never know what this group has on here!

Also, sometimes someone gets rid of a bunch of tools on CL or FB.

The groove is supposed to be there to hold the cable. Throw the housing away and get all new.

Thank you for all responses. I've been working crazy hours and haven't had time to mess with this bike, but I will soon. My 30 day return time ended yesterday.

The sale of the other Technium I wanted to look at has fallen through. The seller notified me that a friend wanted to turn it into a single speed. I asked if I could look at it anyway, as I'm trying to sort out sizing for myself, and also asked after any parts that were to be removed from it. No response:/

So, back to the front derailleur: I have one member suggesting the roughness of the retention assembly may be useful and another saying to replace. I'm considering removing the burr from the groove and continuing to use the existing assembly. I understand that if I deepen the groove, that may cause slippage also.

I'm going to order a new cable and front derailleur, get some new wrap on the handlebars and get it riding, then go from there. Wish me luck!🍀

I cleaned and lubed the front derailleur, took a magic eraser to it, gave it fresh wrap and it's looking and riding pretty good!

Looks great with matching HB tape. Techniums are well regarded bikes, you'll get your money out of it for sure.

Thanks Will! I'm still fiddling with it. It's got a toe trap on one pedal I haven't been able to get off, I've got a pair of water bottle holders on it now, and I'm going to drop the seat and bar stem an inch each and rotate the bars down a bit. I'm not done fiddling with the travel on the front derailleur yet, either. Fun!
