Re: SHORTER CRANKS

Don't forget if you shorten cranks, bottom pedal position is higher off the ground - so you need to raise the saddle to maintain foot at bottom of pedal stroke adjustment. Raising the saddle means she'll probably have to hop off the saddle when stopping at junctions because she won't be able to reac...

Re: Shimano BRM-420 V brakes

As far as I know you can't dismantle the pivot on the brake arm. What you can do is remove the brake arm from the frame (helps to turn pad vertical for this), unhitch the spring from the tab near the top of the brake arm. This allows you to rotate (by more than the operating on/off range) the alloy ...

Re: Was having a nice ride today until this happened.

what do you do? Indeed. If you go in moaning like hell (esp on a busy saturday) they'll probably try to sort you out on the spot asap, as much to get you out of the shop as to sort you out. If you go in Mr reasonable - when you know the boss (or amenable deputy) is in, point out shoddy assembly, how...

Re: jacket advice

I use Freestyle gortex (around town) and gortex XCR (touring/club riding). I find both fine (XCR better + more vents), but sadly Freestyle no longer available.

Re: Chainring Enquiry

When in a former job I was doing up used bikes, a few times I tried old plain toothed 28/38/48 rivitted triple cranks (cheap solida/Stronglight). On indexed gears, the front simply did not change up at all (gear cage was not worn/gear correctly positioned). Pulling on exposed gear cable made it work...

Re: MG TF Bike rack

Try Thule - not the cheapest, but they do have a long list of models/years which their various racks fit :- http://www.thule.co.uk/appguide/ - (you may have already looked here) Here "fit" accounts for aluminium/fibreglass hatchback that might shed your bikes all over the motor way - as my...

Re: Spares

1. Re cables, get outers cut to useful lengths when you buy them, or buy a 1/2 decent set of cable cutters (was a forum topic on this not so long ago) 2. Outer cable end cups - esp outer gear cable ones. 3. Rim tape (split tape can give you punctures) Get the right width, too wide a tape and very ha...

Re: Front changer trouble

From the photo, front mech as viewed from above looks good (not rotated round on seat tube). 3 things to check 1. The mech is at the correct height (1-3mm gap between top of outer ring teeth and underside of outer edge of front gear cage when outer edge is just above the outer ring teeth). 2. Has th...

Re: Help in identifying bike

Photos of head tube lugs, drop outs and BB shell might help ID.
I bought some weinmann 605s in 1979 if that helps dating.
I guess Tange headset (if original) might help in dating, but that might simply date the Argos renovation.

Re: SHIMANO BOTTOM BRACKET

I don't use them (my old stuff still runs). The word I get is to replace the external bearings/cups with Hope ones (colour choice too!).

A computer buff tell me this simply means the website uses software that may be safe/competent in itself, but they have not submitted it to Microsoft for testing/compatability. Am open to correction on this. Its abit like Mr Shimano saying you need to use Shimano cables/chains/cassettes for his gear...

Re: Shimano nexus 3

Nexus 3 not much different to SA3 really. Threaded toggle chain is much the same, but Mr Shimano has an adjuster barrel threaded at both ends, LH tread at 1 end, RH thread at the other. In adjustment/removal terms its the same, just screw/unscrew the adjuster barrel. Adjustment is set by adjusting u...

Re: cantilever brake adjustment.

584 is 650B I think (basically a French size), almost 26 X 1 3/8 but not quite. You can get 650 B tyres (not good ones though), but not the wheels. Cheapest option would be 26x 1 3/8" (590) (available in alloy, usually bolt on), and thanks to the dutch, get in decent quality tyres. A 590 rim wo...

Re: Headset

If its A head (threadless), I'd be suprised if the star fangled washer had fallen down (normally they are quite tight). If it is, simply fit a new star fangled washer as Brucey suggests. If its the older quill type, normally you can 1. Put the stem bolt only (remove from stem) down the fork column a...

Re: Chains and Emulsifiers

Chain removal by breaking the chain OK for 8 speed or less, otherwise you will need to use the special joining links for 9+ speed (in theory tool free breaking/removal of the chain then possible - I say in theory as I rarely manage to push the links at the right angle to open). Joining lings also av...
