Re: Cassette options (if any) for 6-speed system

Yes, but the new cyclist this bike belongs to will probably find it much easier to use indexed shifting properly, so they'll have to stay I'm afraid.

PM sent Brucey - thanks for offer!

Re: Cassette options (if any) for 6-speed system

Cheers Brucey.

Looks like the least hassle solution would be to try to vary the rear mech pull, if possible.

Failing that I'll need to buy and re-space a 7S cassette. Maybe get some spacers made up somewhere.

For the moment the original wheel and 6S freewheel will stay put!

Cassette options (if any) for 6-speed system

I've been recomissioning an older bike for a currently non-cycling friend and it's running a cheapo 6-speed indexed gear system consisting of very basic mechs and 'E-Z Fire' twistgrip shifters, with a 6-speed freewheel with the older style twisted-tooth design. I've acquired a newer cassette rear wh...

Re: Kool Stop vs. Swissstop?

Having used Swisstop Green (for ali rims) on my summer bike and Koolstop Salmon on my commuter and winter bikes I'd go for Koolstop salmon as it works well from the start and is the most resistant compound I've found to tearing bits of aluminium out of the rim, rim wear is reduced with the salmon bl...

Re: Mavic rims - thin sidewalls (again?)

Ouch! Pretty graphic demonstration of what happens!

15k is pretty good though, and especially given the greater braking demands of a tandem. No wear indicators on that rim I assume?

Re: Shimano Brake Blocks

Every time I've used Shimano blocks they've picked up loads of aluminium from the braking surfaces of the rims and scored the rims. Admittedly I've avoided them for years now so not tried the latest. Can you get Koolstop Salmon (the colour of the compound) inserts for your pad holders? They are the ...

Re: Disc Rotor Cleaning

I tend to use just a damp cloth. The holes can hold more muck as Brucey says so maybe a nailbrush would be handy to dislodge some of this then wipe with a damp cloth, perhaps with some soap if there's any oil or grease on the rotor. Much less hassle than constantly cleaning the rims of rim-braked wh...

Re: Shimano 105 Chainring - Alloy specification ?

Having used the Spa 7075 'rings on my winter bike for a couple of winters I find them very good, with a good quick shift. Having used TA and also Stronglight Zicral rings previously I reckon the Spa shift at least as well. Just bought a set of 3 for my commuter for about £51 which is little more tha...

Re: Huge increase in price of Surly Ogre forks

Bought some Surly Disc trucker 26"-wheel forks myself about a year ago and cost £65 via a local bike shop.

Re: Decent front battery light - Recommendations?

Thanks for the recommendations everyone.

Would rather avoid proprietary battery packs in case I can't buy another one when the time comes. Will have a look at some of the options in this thread.

Cheers,

Re: Mavic rims - thin sidewalls (again?)

No, I didn't. Will have a look later this week.

This is the third new rim-brake Mavic rim I've had which has measured 1mm or less from new, the other two being a similar design and maybe teh same model on a pair of wheels built for me by Rose Cycles in Germany.

So far one wore through in 2k miles.

Re: Mavic rims - thin sidewalls (again?)

My sticker doesn't have 'disc' on it so I guess is intended for rim brakes.

So it's still cr@p then!

Re: Mavic rims - thin sidewalls (again?)

Oh well, maybe my 'free' wheels isn't much use then, since I need it for a rim-braked bike! Funny how the braking surfaces are silver though (but rim hasn't been braked on) and the rest of the rim is black anodised?! However, I've noted similarly thin sidewalls in another set of Mavic rims for rim b...

Re: Top swing or Bottom swing?

I wore out three different top swing mechs in the space of a couple of years commuting, starting with a basic one them moving up to Deore LX and finally XT. Finally replaced them with an XT bottom swing type about 12 years ago and no problems since. The bottom swing mech (Deore XT) on my winter bike...

Mavic rims - thin sidewalls (again?)

Was recently given a free 26" wheel built with a new Mavic XM317 rim. Measuring the rim sidewall with my Iwanson dental caliper (essential item for around a fiver IMO) revealed a braking surface thickness down to 0.9mm in places and always less than 1.2mm thick. Added to this there is no visibl...
