Old Trek 1000 advice

[faffer]

Hello,

My friend has an old Trek 1000 (one of the yellow framed ones with blue lettering), must be at least 15 years old. I've attached a photo that *isn't* his actual bike (found it by Googling) but it looks like the same model/era to me.

Some of the components have obviously already been replaced over time (new wheels and bottom bracket). He needs to get a new chainset and cassette. Could anyone help with the following?:

a) What size cassette could this frame handle? In general can you fit 9/10 speed cassettes to older frames?

If he just wanted to buy new rings rather than replace the whole chainset is there anything to watch out for - eg some of the adverts for chainrings specifically mention that they are 9-speed, does that mean they couldn't be used with an 8 speed cassette? My understanding is that his existing setup is a 130 pcd (170 arm length). His existing rings are 42/53, I guess he'd just want that again unless there was reason to change.

c) Does the type of derrailleur and shifters he already has make a difference to the choice of the rings/cassette?

d) Any other help/advice you can think of much appreciated!

Thanks,

Sadly we need a lot more information about what exactly he currently has. At 15 years old there's a chance the bike doesn't have a cassette but has a freewheel.

Assuming the shifters are indexed then he's limied to whatever size cassette/freewheel he's currently got fitted. If he's currently got a 7 speed freewheel on there that thats what he needs.

No it will be 130mm rear spaced - it's much newer than my Herety....or Ribble 653.... they are 130mm

With wheels now, that are Shimano compatible, you can run 7-10 speed easily on them (7 speed need an additional spacer - no big deal)...........

It's Shimano 130 - so just go to Ribble Cycles for Stronglight chain rings - choice of cheaper Dural or more pricey Zircal chain rings.... if you need to....

New chain.

Just buy any up to 8 speed casette, - e.g a HG 50 8 speed casette..... any 8 speed you can strip it to 7.... and even use the spacers..... (just undoo the locking allen key fitting on the biggest sprocket)

Going to 9 or 10 needs new shifters, new cassette totally, and possibly a mech.

TBH, all you need is a new casette and chain - the bigger 'chainwheels' will most likely be OK...

That's really helpful, thanks very much. Time to go shopping!

Ah, ok, scuse my ignornance but what's the difference between a freewheel and a cassette?

Freewheels screw onto the hub (in the same direction as the wheel moves so they are a bugger to get off) whereas cassettes slide into a grooved hub attachment and are then kept in place by a lockring.

...Sorry - one more question - I'm looking at hg 50 cassettes, there's a Sora version and a non-Sora version, the non-Sora is for 'Narrow 8-speed IG chains'. Which should I get if i'm using the standard Stronglight rings on the front? I can't find any info about whether the stronglight rings are for a particular chain size.

The narrow guage one is on offer so it would be great if it was that one!!! But I don't want to waste time and money getting the wrong thing.

Thanks again

Get the cheaper one. They're the same product, just the waters are being muddied by jargon.
7 and 8 speed chains are the same thing and will work fine on the HG50 cassette.
BTW: Redbike - you do realise that 15 years ago was 1994, not the middle ages!

Brilliant, thanks for the advice.
