advice on upgrading

dominicg

Hi,

I am just about to start upgrading my Trek to Shimano 105 10 speed. I've spent months getting all the bits together and now I have shifters, mechs,cassette, chain and brakes. I've got the Zinn book which is very clear on the method for installing each individual part but can anyone help with the order in which I should make the changes? Indeed is the order important at all.?Please bear in mind that this will be my first go at any major alteration to my bike.

Thanks,

Dominic

Sounds like you also need cables + bar tape.

Take your time about it, grease all screw threads. When it comes to cables, measure twice, cut once.

As it's your first go, make a checklist and tick off each item as you go through so you don't miss anything obvious (like tightening a brake cable clamp or something like that).


EDIT: As per the poster two posts down from this one, use anti-seize grease but don't muck about with those stupid little tubes from the bike shop; they're hideously over-priced. Get a nice big pot from your local motor factors, it will last you forever.

Order doesn't matter, except that cables should go on after everything else.

I built up a frame over the weekend. If you're measuring the chain on the bike (as oppposed to against your original chain) then I'd leave the front mech off cos it can be a fiddly nuisance, then fit mech on and feed chain through.

I did it in this order.

1. fit forks and stem

2. handlebars (so I can turn it upside down and fettle with the rear mech etc)

3. brakes

4. BB

5. Cranks

6. rear mech

7.wheels

8. chain length

9 front mech and fit chain.

10. shifters and cables

11. adjust stuff.

12 pedals/seat post saddle

and going to bartape it up tomoz.

If you havent got any do try and get some anti seize grease, you only need a dab and it will save you loads of bother trying to remove bits later on. Bon chance

And get a torque wrench. Use it on everything - but only to do up, use normal allens/spanners to undo (you'll break it if you use to undo).

As you go along, bolt everything loosely into place until everything is on, then start at the back (or front dependant on your preference) and tighten everything to specified torque settings.

I'd also use this as an excuse to fully degrease and scrub the frame and forks clean so its all spotless - no point transferring ganky stuff onto the new bits. Drop the forks out, clean and grease up bearings, drop pedals out and clean and grease up the threads, same for seat post, clamp, take the seat off and clean everything, etc etc.

As above - copperslip everything up, except moving parts - use stadrad moly for this (copperslip is slightly abrasive, so perfect for nuts and bolts but not bearing seats etc).

Take a whole day doing it and it'll be worth it in the long run.

No point putting loads of new shiney bits on and having skag everywhere else.

Thanks everyone. I feel a bit more confident now.

Cheers,

My guess, since you are upgrading to 105, is that your current bike is a Trek 1.x-series. These bikes use long reach brakes, and if you have bought standard 105 brakes, they will not fit.

If its anything like the basic Giant OCR 4 range, the front will, the back won't.

Hi,

My heart sank when I saw that..and thinking about it Trek 1 series bikes are supposed to have room for mudguards so that comment about long-reach brakes made sense...but... as luck would have it, 49mm drop seemed just right when I tried it yesterday. A bit of luck at last!!!

Cheers,

Dominic
