I just found an old Rock Hopper (mid '90's??not sure) behind my dad's shed during my last visit and I figured it would make a great SS project bike. I want something kinda fast and light - but not really for hard core MTB (I'll leave that for my 6" geared dualie), just an errand/school bike that will occasionally see some smooth dirt.
I've pretty much completely stripped everything off and replaced the necessities with some parts I had lying around - BB, cranks, headset, wheels etc. All except for the rear cog/hub. I have a LX hub (8 spd. previously) that is in great shape and was hoping to use it.
My idea was to break down an old cassette and find a suitable gear ratio and use something like PVC for spacers. Is this a good idea? Or should I get a different hub (BMX?) All of my buddies who ride SS or fixies have purpose built hubs, but I was really hoping to build this up w/out spending one red cent.

Oh, and speaking of gear ratios, I've read a bit on here and got that a 2:1 is a good place to start, but since I'll mostly be on flat and level tarmac, I was thinkin' of going with something steeper like 2.5-6:1??
Thanks for any input on my current situation and for anything I may not have thought of...this will be my first SS (besides BMX back in the day :) )

Certainly you could use your existing wheel and space the freehub to use a single sprocket.
I'd suggest using only sprockets from your existing cassette to find a ratio that suits you and then buying a SS specific sprocket (Surly for example) with full depth teeth.
You'll need some sort of chain tensioner too - get one that can tension by pushing up.

Sorry mate, I forgot that some of those Rockhoppers have forward facing horizontal dropouts....:eek: . I'm not that well up on Specialised stuff.

In that case - yes, a half link (if you need one) and maybe a chain tug on the drive side should get you up and running :) .

yeah... how does that work for forward facing drop-outs? There one on there now (well similar i guess) that looks like it works the same as a chain-tug for rearward facing drop-outs. But it would just push the axle forward (or keep it from going back) from my perspective. Is there something that I'm missing?
-THX

Is there a hole on the dropout?
On both of them actually. Hole, then forward facing dropout...

If you're mostly on flat roads I wouldn't worry about axle slip too much, just honk down on that LX QR good and tight.
If you do have any issues you could swap out the axle for a solid one, and get some good track nuts like these Problem Solvers w/ rotating washers (I run them on both my road and mtb fixies w/ zero problems).


Try a cog from your cassette. Keep on riding it until you start dropping the chain. If you don't drop the chain, just keep on riding it.

I'm sure that it's possible to use a Surly tug with forward facing dropouts. However, I can't speak from experience so maybe I'm wrong. I'm think that I've seen a photo of just such a set-up though...

I made the switch to SS when I was still in Chico and I was very happy with 2:1 (32x16). All over the road, Lower Park singletrack, Upper Park rockgardens, even up the North Rim Trail, that gear combo worked for me.

Be prepared to feel like a kid on a new bike again. :thumbsup:

i'm sorry, but I don't quite follow...hole=forward facing???

yeah, I've got a solid axle and some nuts lying around that I was gonna swap out for the QR - I dont think I'll have any probs. I just could not see how how chain tugs would work w/ fwd facing drops - I guess I need to see a photo

yeah..I'll be running a 42 up front, so I think I'll start off with a 21 out back then - If I'm spinnin too much, then I'll just throw on the next gear up ( 18t i believe)
