Dump Pick: Specialized Sirrus Shimano 105

saw this at the metal pile today. lightweight. dirty, but paint ok. looks like intact groups except for handlebar and stem and pedals. not too knowledgeable on bikes overall, so turning to the "experts" to tell me what i have, worth saving/improving. thx.

Don't see a pic, But Sirrus with 105 is worth saving, even if for parts. If it is not rusted to death I would grab it.

Nice catch and worth saving and even upgrading with ultegra/duraace 10-11 speeds and a better set of wheels

Sirrus was one notch below the Allez, and from what I read, shares the frame geometry/design. Great find, especially in good shape like that. The 105 gruppo is mid-level and quite nice for a ride like this, as are the Wolber GTX rims; I wouldn't kick any of that out of bed. If you decide to replace that abomination of a bar/stem with a drop, I might have some 105 aero brake levers I could send you for the price of postage.

Thx for the feedback and generous offers. I donít have a lot of bike tech savvy developed, though I have high mechanical aptitude.

spent about an hour cleaning the bike. Used some of my favorite products: camp fuel in a spray bottle for grease, tooth brushes, rags, dirtex in warm water for general cleaning, blue scotch non scratch pads (and music!).

bike us in really good condition for its age. Components look good. Rear hub is 105, front is campy. Tires hold air.

gotta move onto other errands right now. Please keep up the suggestions, I will return. Looks like the serial number is CB012312

That Specialized stem is, except for the marking, the same as a Nitto Technomic, and actually, I might have one or the other to spare, in some woefully-disorganized pile somewhere. Handlebars are expensive to ship and easy to find a local bike co-op / kitchen.

Seat post -- any Strong or SR of the right diameter should suffice.

GB012312 would be a Giant built in the 2nd fortnight of 1990. The Sirrus and the Allez used the exact same from 1987-1990, but the Sirrus (at least the 80s ones) got softer, lesser paint and 105 instead of 600 parts. I have a 1988 specimen in red I scored for $50 couple of years ago for the infamous Clunker Challenge, but this bike is most definitely NOT a clunker. I'll echo @madpogue on the original bar and stem being Nitto products branded Specialized. I keep wobbling on mine - the dropped bars came to me bent a little, and I keep looking for a deal on 42cm Specialized marked Nitto bars to replace them.

This is SO well worth putting to rights! I am on the verge of thinning my herd of bikes, but I think this one is a keeper. It has simply the most intuitive, perfect handling of any of my bikes. I've left mine box stock gearing wise, as the original 1988 6-speed Uniglide system is in good shape and shifts smoothly and reliably, and I just grit my teeth and go with its stock 13-26 cluster. It came to me with a 39T inner chainring which I replaced with a cleaner one, but apart from a thorough cleaning, some touch-up paint, consumables and repacking everything it's just lovely. You made a screamingly good score there! If it fits, you have a serious keeper!

As others have noted, definitely worth saving. I love my 1990 Sirrus that I picked up for $25 last August. One of my favorites! My serial number is GE005650.


Condition when purchased.

i'd like to track down the missing original equipment first, though not sure how hard that will be. then go from there. it won't be a showpiece, but should present well. so, i guess: seat, post, handlebar, stem, pedals, brake levers. i do have a pair of nice shimano 105 clip-in pedals (with black/red Giro shoes), though i generally prefer basket pedals.

Finding the parts for this should be fairly easy there were a lot made, not particularly rare parts. If you have a local bike co-op that is always a good starting point, ditto on a local shop (if they do vintage). You might be able to find things locally on Craigs/Offerup/Facebook Marketplace. Ebay will definitely get you sorted, just a matter of for how much and shipping. There are a few stems listed now, some cheap some pricey. This site BF, has a "wanted to buy" thread, and members here tend to have deep parts bins you can also try that.

i am relying on the article posted above, plus suggestions from experienced folks here, to guide me in returning this bike to proper condition (mainly OE). please feel free to create your own suggested list of specific parts to shop for, as well as cosmetic improvement suggestions. thx!

In 1988 they came stock with 700x25s, but I don't think there's enough clearance for a 28mm tire. That is actually my biggest complaint about the bike. I have not done the measurements and research needed to determine if I could do a 650B conversion of mine ... but I have other bikes that are more likely candidates for that.

don't mean to hijack my own thread, but i've had this other bike, a mid-90's bianchi forza, hanging around for a long time (another family members bike). i believe it cost about $500 retail. any feelings towards it? might sell it one day to pay for other stuff, but have no idea if it is worth that effort.
