Re: Upgrade to rear mech on 1992 Raleigh Dynatech

You can use ... any 'road' 10s mech (but not RD-4700), capacity allowing. cheers Oh, sorry about my previous post about not knowing what RD-4700 is. I assumed it was a mountain bike groupset, not having fully read your post and - embarrassingly - having forgotten that it is exactly what is fitted t...

Re: Upgrade to rear mech on 1992 Raleigh Dynatech

May be a Shimano Claris RD-R2000 8 Speed Rear Derailleur - Silver - SS / Short Cage or SG /Long cage would be a good match. As the other posters have said it will work fine with a 7 speed chain and cassette - and will work with your shift leavers the same as a 7 speed one. Forgive my ignorance, but...

Re: Upgrade to rear mech on 1992 Raleigh Dynatech

Not even close. Deore DX and LX were near the top of the shimano heirarchy and acera is near the bottom. ..I'd suggest deore LX or XT parts if you want them to work well and to last well. cheers Just as I feared; yep, 'work well and last well' is what I have come to expect on this bike - but can I ...

Re: Upgrade to rear mech on 1992 Raleigh Dynatech

you can normally use an 8s cassette with one sprocket removed in place of a 7s one. You can use any shimano mech that is 6s,7s,8s (but not RD-7400 series) any 9s mech, and any 'road' 10s mech (but not RD-4700), capacity allowing. cheers Thanks for this advice. I am guilty of not explaining my aims ...

Re: Upgrade to rear mech on 1992 Raleigh Dynatech

Just because you have a 7 speed system you don't have to have a 7 speed rear mech. You can happily use an 8 speed one (or even a 9 or probably a 10 speed one if you want). You just need to consider the capacity and sprocket sizes. What chainrings and cassette do you have? that will enable us to sug...

Upgrade to rear mech on 1992 Raleigh Dynatech

I have just completed a refurb on my 1992 Raleigh Dynatech Encounter. I have the impression that the mechs really are end of life but I guess I won't be able to get a replacement 7 speed rear mech, will I? I assume that 8 speed is still available, but would an 8-speed cassette fit on the hub body? T...

Replacement brake blocks for Shimano BR-M550

As part of refurbishing my 1992 Raleigh DYnatech Encounter I have stripped the brakes completely. Although they still work well, they are looking a little tired. Firstly, if nothing else, the brake blocks - still the originals - should be replaced. I searched all the obvious sites but found nothing ...

Re: Replacement securing bolts for chain ring

I have to say this forum is the most pleasurable to use, out of all the forums I access, irrespective of topic. Like a dummy, I ask daft questions and get helpful answers, quickly. That's 2 characteristics that differentiate this forum from others. Could I now be so bold as to ask a supplementary? B...

Replacement securing bolts for chain ring

The photo shows the securing bolts and 'collars' that I have removed from the chainring (Deore LX M550) on my Raleigh Dynatech MTB. AS you can see some of them are corroded, some are a little damaged by the clumsy use of an Allen key. Are these bolts still available as a set? When putting them back ...

Shimano RD-M550: Unknown adjustment screw ?

In my continuing efforts to better understand the bits on my bike (and why they really haven't worn out after 28+ years....) could you please look at the attached photo and tell me what is the purpose of the relatively large round-headed screw with a small index mark, which is normally hidden beneat...

Re: Shimano FD-M550: correct way to clamp cable?

OK fellas, it's clear I did not clamp the cable in the correct way.


I'm really thankful for the quality of the advice/answers on this technical forum. It creates a lot of credibility. Thank you.

Adjustments on Shimano Deore XT integrated brake/shifter

There are two 'adjustment' screws on my Shimano Deore ST-M095 integrated shifter/brake. See the attached photos.

What are they for?

Shimano FD-M550: correct way to clamp cable?

In trying to understand the cause of a very stiff operation of my front derailleur (mech = FD-M550; shifter = ST-M095) I have received 2 different recommendations on how to pass the cable through the clamp. The route I chose was to pass it in a straight vertical line after exiting from the cable gui...

Re: Very stiff Front derailleur shifter - why? What possible replacement?

Cable outer length too short? It should go straight for about 2+ inches at least, before bending, at any point where there's housing going into anywhere. On a road bike with the cable under the bottom bracket that narrows it down to the cable housing coming from the left shifter. This is for a rear...
