Edward1066 I love that paint job. I've seen a few different Hard Rocks & Rock Hoppers of that particular style that folks have tricked out, and I'm always jealous that I haven't found one in my size. I dig the attention to detail with the pink, white and yellow cable housing. Great job!

This is a soon-to-be upright bar conversion, a 23.5" Specialized Hard Rock

At the local bike co-op, there have been so many donations during the pandemic that they're running out of space to store them, so they've been selling a lot of bikes off whole rather than breaking them down for the parts bins.

I spotted this huge steed in the pile, and picked it up for $40, which also includes digging rights to upgrade whatever I want. So it's going to be a parts bin special, apart from one or two special touches I've got in mind. A buddy dubbed it "The Black Prince" and the name has definitely inspired some of my thinking. Here's the before:




23.5" Specialized Hard Rock. I'm not sure of the year. I've looked through all the catalogs, and most of the Hard Rocks have the model name on the down tube and Specialized on the top tube, whereas this one is switched.

So far I've swapped out the saddle and pedals with stock ones I took off my wife's Marin step-through when I upgraded her stuff. They're probably just placeholders, but were absolutely necessary to take it on a good shakedown ride. As for the rest of the parts, here's what I've got on hand or on order:

- Shimano Deerhead Gruppo (a buddy took them off his Ross Mt. Whitney when he changed it over to a 1x, and doesn't want them to go to waste, so he's gifting them to me)
- 26" Simworks x Panaracer Homage tires (with slime tubes so it's indestructible)
- 1" - 1 1/8" threadless adapter
- Kool Stop pads

I spotted a silver Deore triple in the parts bin when I was last at the workshop, so I'll probably add those. I want to put some scrambler / klunker style bars on this - likely silver to match the gruppo and the cranks - so I've been considering the VO klunker bars (when they come back in stock), but I've also been super inspired by some of the builds BicycleSafari has shown off, so I'm hoping he can point me in the direction of his preferred scrambler bars and stem.

Eventually I'm sure I'll get to the point where I've swapped out everything but the frame...and then maybe I'll swap out the frame as well, if I come across an upgrade that's also gigantic.

I showed my wife the custom paint jobs posted by Crankstank, and she's currently on Pinterest looking at other custom jobs...so she may be adding to this as well. Right now we're leaning towards a black / silver / forest green color scheme. I'll be cranking on it over the next few weeks, so hopefully there will be a followup post soon.

Lovely execution. My mind went straight to Stumpjumper instead of Hardrock, forcing me to do a double-take. This is late 80's: '89 to be precise.

Edward1066 , are those grips the Ergon GC1 BioKork? Do you find the grip's curve is sufficient for the sweep of those Nitto Tosco bars?

I think they're about right. Comfortable on a 6 hour ride this weekend.

I'm really with how it rides. Wish it was one size larger, but those are extremely rare. Thanks!

Trust me, I know! My 23.5" Hard Rock was a needle in a haystack. It's almost like tall folks were ostracized from mountain biking in the 90s.

I put many miles on the same model and same color Hardrock Comp.

I eventually did an at home repaint to a burgundy color.

That paint got scratched up from lots of use.

That 21.5" frame is hanging in my garage.
It's a fine riding and tough frame that could take whatever I called on it to do.

I measured the frame and fork weight at the time which if memory serves came in at 8.00 lbs total which was just 1/2 lbs. or perhaps a bit less difference in my Rockhopper of the same era.

Enjoy and safe riding!

What did you use for the seat binder bolt? I want to do the same thing and have the old heavy quick release.

I use something like this 6 x 50mm seatpost binder from Dimension: https://www.universalcycles.com/shop...ils.php?id=918

In principle, you could use an M6 bolt of appropriate length from the hardware store. I like the part that the bolt head sits within on the Dimension product. What I don’t like is the aluminum nut, because I’ve had the threads of an aluminum seatpost binder strip out. (On a ride! Ugh.) So I use a stainless nut with a flanged base, plus a washer, from the hardware store.

What's the stem you have on this? I've got cantilever brakes, and I love the clean lines of the built-in cable stop.

at the risk of coming off like a critical chump, your bar grips are reversed. the wider portion is supposed to face inward to rest your palm on. of course, it's however you like it.

Ummm... well, I disagree. Look at the left grip. The "wing" palm-support comes inward like it is supposed to. I use these grips a lot, although never on pull-back touring bars. They make several versions: The GP1 is for straight bars, and the GC1 is for slightly swept bars. Like this:

there are TWO versions......i see!! GP1 has the wing and securing bolt same side/facing in while GC1 has them opposite!



well, from the angle in this photo it looked like the wings are facing the wrong way, but then... they're not GP1's.
you can see how i'd mix them up, though, right?

Looks like a BMX quill stem, but I don’t know which one.

One of my kids bikes has something similar.

Check the other pics, the flanged portion is to the inside, they're GC-1's designed for swept back bars. Thanks for checking...

You sure said it. I really really love the built in cable stops. I'm excited to start fabricating my own threadless stems with integrated stops. The only information on this quill stem is that it is an SR 22.2 from Japan. They were very popular on early 80's mtb/atb and I keep an eye out and pick them up whenever I see one for a decent price. Some people refer to them as "golf club head" stems, but you wont get many google hits on that. I found a link to one here
https://for-sale.yowcow.com/listing/132155476/
I've seen a few of these out there that are 0.833 (21.1) so if you do find one just double check to make sure it works for your project.

i caught that detail after he'd made the distinction between the two version of ergon grips. the flat bar version has the securing screws to the inside (which is where i was referencing from in my assessment). the swept back version has them to the outside. plus, they're generally shaped different

This was totally enough for me to go on to find some more info:

It's a stem from Sakae-Ringyo. This is what is most likely the 1983 catalog https://www.velo-pages.com/main.php?g2_itemId=58566
