Project strip down and rebuild

[sotal]

I think I've found all the bits (or nearly all) that I need to rebuild my road bike.

I'll post photos as I go and questions when something doesn't quite work.

I asked a bit about this before starting and decided to go for it.

The bike is a Trek 1000SL. I bought it second hand and have had it for years. It has got to the point where lots of bits were getting worn out but the frame is in perfect condition and the frame and fork seem to be relatively light (carbon fork). The bike also fits me really well, so I decided that, even though it may not make the best economic sense, I would buy new components for it and I would change to a double, which I understand is a hotly debated topic but I've never had a double and if I do but a new bike in the future it looks like it is likely to come with a double so I might as well see what it is like!

I've managed to source the following...

A pair of Shimano tiagra 4700 shifter in great condition (second hand)

A tiagra 50/34 crankset which has only done 50 miles before being taken off, along with a 4700 front mech and 4700 long rear mech which had also only done 50 miles.

A new KMC chain.

A new 11/34T 4700 cassette.

A new ultegra BB.

A pair of new 4700 brake calipers.

A set of new optislick gear cables (inners and outers).

A set of new brake cables (inners and outers).

A set of new bar tape, changing from white to black as the white always looks grubby.

Is there anything else you can think that I might have forgotten?

I have all the tools to disassemble my bike. I have the hollowtech 2 tool. I have a variety of greases.

My first challenge to look at when it arrives is that the front derailleur comes with a the slightly smaller clamp. Mine needs the 34.9mm and this comes with a 31 point something mm clamp.

Can I buy a new clamp the correct size on its own? Or can I use the existing clamp and just bolt that to the new mech?

I'll post pictures as I go below!

The clamp is integral to the derailleur but you might find you can make it work.
Good luck with the project.

No, the band-on RD with a 31.8 band will not fit your 34.9mm seat tube. "you might find you can make it work" - sorry tell us more @Cycleops
Good news is that FDs are not expensive so go looking for a 34.9 band-on FD or find a braze-on and an adapter.
I am about to build up a new (to me) frame. Here's the relevant section of my list (weights in grammes):

STIs	504​
Cable, brake, front	20​
Cable, brake, rear	39​
Cable, brake, front, outer, compressionless	45​
Cable, brake, rear, outer, compressionless	90​
Brake, front, TRP Spyre	176​
ISO to post mount adapter	34​
Brake, rear, TRP Spyre	176​
ISO to post mount adapter	34​
RD	283​
FD	113​
Band on to braze-on adapter	29​
Barrel adjuster, FD cable	4​
Cable, gear, front (incl outer and ferrules)	37​
Cable, gear, rear (incl outer and ferrules)	58​
Cable ends	2​
Cage, bottle
Cage, bottle
Stem	196​
Bars	320​
Bar tape	90​
Bar tape gel pads	90​

Yes the FD didn't worry me too much as it was one of the cheapest options. I was just hoping the clamp might swap over. The new one is a tiagra 4700. The old one is a tiagra triple 2203. The old one just bolts to the clamp so I was hoping the new one would too and I could just bolt it in place.

It hasn't arrived yet though, so I can't check it yet.

Looking at tools, I might need the tool to set the tension on the bearings when putting the cranks in. I'm not sure if I've got that one. Again when they arrive I'll check.

Now, THAT'S a pile of parts!

Now, THAT'S a pile of parts!

Just waiting on one final part now (I hope!)

 

[sotal]

The final bit came so I stripped everything off the frame ready.

I've being weighing all the different bits just to get an idea of where the weight is on the bike. Obviously I'm not going to get obsessed about weight because otherwise I'd have bought lighter components than tiagra but there are odd little bits where it might be worth making savings.

So far comparing the new bits to the old there was a bit of a saving from the old cranks and BB to the new ones but a lot of that was lost with the larger cassette on the rear. I'd say there probably isn't going to be much in it weight wise between the old and the new.




Weight wise the frame comes in at 1.6kg as pictured above with the headset still in place. How does that compare with more modern bikes (it is a large frame)? The carbon fork adds about another 500g.

 

[sotal]

So the frame without headset is about 1.5kg which is no light weight but not horrendous from what I can see.

The wheels I think may be a little on the porky side.

The front wheel is: 915g without the tyre and tube.
The rear wheel is: 1095g.

The only other two areas that stood out to me as being a bit heavy were...

The seat and seat post which weigh 734g with a rear light attached.

Stem which weighed 207g.


I don't know if any of those things are worth the cost of replacing though?

 

[sotal]

All the bits are now back on, just got to put the cables on and set it all up.

I did break my torque wrench though doing the left hand thread on the BB, something seems to have snapped inside 🙄

Loving this thread. Very new to bike maintenance, etc would love to one day rebuild, etc. Still struggling with derailleurs for now (lot's of useful videos). Glad found this forum, great to browse

How’s the headset?

I ask because mine need replaced and it’s not been easy to find a replacement as the original is no longer produced. Trek support eventually gave me the relevant part number for the current substitute: 423140. If yours needs replaced hopefully this will save you a bit of time.

I have ordered it via Evans but the only one they could find anywhere was in The Netherlands and three weeks on I’m still waiting for it to arrive. That’s not a problem as I no longer use the bike and I’m only fixing it to sell it.

(edited to correct the part number)

 

[rogerzilla]

1.5kg for a bare frame is light. A large 531C double-butted steel frame from 30 years ago would be about 2150g (bare, no fork).

How’s the headset?

I think it is ok, I've left it for now as it all feels smooth. I had an annoying creak on the bike before which I really hope has gone now. If it hasn't then that'll be one thing to look at, but the things that caused the creak wouldn't have fitted in with the headset anyway.

Basically it creaked when my right foot was between about 2 o'clock and 6 o'clock and it was under load. It also creaked when coasting if my right leg was extended (my default coasting position).

It sounded to me like it was coming from the front wheel area, which hasn't had much changed but the bottom bracket was well in need of replacement so I'm hoping it was that.

The current headset is a crane creek one, does that fit in with the part number you ordered?

It looks like the wheel weight isn't horrendous. I was looking at some Shimano 105 RS300 wheels that were on offer and they actually turned out to be slightly heavier than mine, so to get much lighter, I'd have to pay more than I wanted to!

Yes, it's a Cane Creek part - €29
