Suderp.

Honestly idk.. i just put brand new oury grips on it.. it has default pure fix wheels. came with a worn out aluminum crank so i have half aluminum half steel. so its pretty basic. nothing too special

Photo?

If you can get $200 for that, take it and run. Don't look back, don't take their calls or text messages for a few days.


But, but, but it's in the great big book of fixed gear mythology, written by the people who know.

Changing from a purefix to those aluminum track bike is a big jump I.M.O. !
I'd say change the chain first, I never had a purefix but I'm sure they use a KMC chain.
I had a KMC chain on one of my bicycle, it snapped on me while stopping, thank God it wasn't a hill though.
Then I would move on to the crankset along with a bottom bracket, maybe a sugino messenger ?
It treated me well, hill climbing everyday. You will feel a big difference when you really push on those pedals.
Then I would change the wheel set, I know they come with heavy deep profile rims.
Get a new cog and lockring , surly is decent for its price !
Pedals- This is your preference Efficiency < Comfort ? Bmx pedals with straps, or road/track pedals with cages and straps.
Then your stem, handlebars, headset, etc
I made a mistake and started with handlebars first, I kept buying different types of handlebars then I couldn't afford to upgrade my parts.
After all that you can just throw the parts on your purefix on to a new frame !
Hope this helped you decide !

There's nothing wrong with KMC Chains.

One KMC chain failed = All KMC chains bad? There's alot of different quality KMC chains on the market. You get what you pay for. I've ridden over 11,000 miles on KMC chains in the last 3 years and never have had a problem with 710 series or better.

If I were broke, I'd still use a z410 over anything else. And yes, I've used other chains.

No they're really not. They're loud and overpriced. Their lockring is OK. For that price, you can do better.

Or get really radical and get clipless pedals. Oh the horror.

I have a surly cog with a kmc chain, and the combo is dead silent.

I wouldn't follow any of this advice.

I've used KMC Z410s solely on my bike and have never had any problems.

KMC chains are fine. Also, to say "KMC chains are bad" is pretty vague considering they make a lot of different types.

KMC chains are all that I'll use road or mtb.

I'm sorry for the misunderstanding* ? The KMC Zs were fine ! The 710s failed on me, it was my fault because I never did any maintenance on my bicycles back then.

Incorrect.

You will absolutely feel the difference. Have you owned/ridden both? I have (KiloTT/Leader722ts, Cinelli Bolt) and it was a massive difference whether I was climbing, on the track, or riding around town. 5-7lbs is more than noticeable, let alone the difference in frame material.

I've got exactly both. My townie is a 22lb felt brougham, and my track race bike is a cannondale Alu bike that's about 17lbs. They feel about the same on hills, but we don't have anything very sustained, mostly just punchy short stuff, so weight isn't as big a factor. I'm also 180lbs, so the % of my weight may be much smaller than others.

Your mileage may vary.

Those long, forever, not all that steep to the top hills are the ones that do me in.

But they're also the one's that are the most fun on the way down IMO. On the steeper hills, I can't really spin fast enough to just bomb down the hill.

I go around those, because lazy.

False flats are the worst.

They make me feel like a weenie because it looks flat, but I'm dying

I like false flats.

This thread is a false flat.

Is that when you forget to pump up your tires before the ride, so you spend the whole ride thinking you've got a flat?

JK, +2

False Flat

I thought it was that squirrel at work that always wore a ton of loose clothe, then one day you saw her at a party wearing a tight dress.
