Re: Shimano 9/10/11sp compatibility

Ok brilliant, thanks people! As long as the cassette slides onto the same splines I can deal with spacing issues.

Shimano 9/10/11sp compatibility

My son's just trashed a rim, it's only a few quid extra to replace the wheel rather than rebuild... but the nearest version I can find says 10/11sp. It's the first time in years I've had to think about this stuff so I've kinda forgotten what's compatible with what - will a 9sp cassette go on a 10/11...

Re: Do people using spiked tyres leave them on all winter no matter what the conditions?

Hi Raph, Thanks for the message and information. Also it's handy to hear from someone who does change wheels to suit conditions. However for me I don't have derailleur gears because my bike has a Shimano Alfine Internal Gear Hub although the same principle could apply with a worn chain not matching...

Re: Do people using spiked tyres leave them on all winter no matter what the conditions?

Haven't read the whole thread but just to respond to one point made - about having a spare pair of wheels with studded tyres and the fact that the chain will have had a year's wear by the time you next put your ice wheels on... A new chain skips on a worn cassette, similarly on worn chainrings, but ...

Re: Do people using spiked tyres leave them on all winter no matter what the conditions?

A spare bike is a good idea if you wanna keep yer posh bike clean... but if that's not an issue then you only really need a second pair of cheap S/H wheels and leave the studded tyres on them, that way it's quick to swap over when the weather turns icy, and doesn't take as much space as a spare bike...

Re: Front light using AAs or similar...

Well... I went up ye Pyrenees eventually, months ago now but I'd forgotten about this thread... The dynamo was great, Hope light was great, hardly used it, another little USB chargeable backup light was also great (cost £20 in the LBS runs on one 18650 but doesn't have a brand name), half the rides ...

Re: Front light using AAs or similar...

Got the Hope LED 1 in the post, it's seriously good, thanks again to iandriver for the suggestion. Even if I don't use it on this trip, it's the only decent light I've now got that doesn't have a separate battery and associated hassle. Nevertheless... I've put together a pack of 10 AAs to make the r...

Re: Front light using AAs or similar...

Thanks for the Hope LED 1 suggestion, I'm waiting for one in the post and I reckon that'll sort me out. Thanks for all the help! From my off road experience, where you mount if can make big difference. A helmet mount where you can direct it can be a real bonus. It's up high and can see into dips be...

Re: Front light using AAs or similar...

I've just ordered a USB Werk - thanks for happening to mention it! Regardless of bike lighting, I know direct sunlight isn't reliable in the Pyrenees at this time of year, it's a bit like Wales! ...and there's a phone to keep charged up, plus I think I'll be using an Exposure Blaze rear light, which...

Re: Front light using AAs or similar...

Hey that looks great. My only worry is that as the weather is very variable at that time of year, I can't rely on lots of direct sunshine so I reckon charging will be slowest when good lighting is most needed, ...with that in mind I'm interested in your mention of the eWerk - how do you switch to al...

Re: Front light using AAs or similar...

Thinking aloud, it's just occurred to me that it might be possible to charge a single 18650 at a time from a 16W solar panel I keep spread out over the panniers. If I can get a 18650 charger to run off USB that might be the answer, though it only puts out the whole 16W in direct sunlight and I've go...

Re: Front light using AAs or similar...

Are 18650s the ones that can be approximated by a holder for three AAAs? Yes, however lights intended for using both options are of a larger diameter, and have a plastic sleeve to keep the 18650 central, and an extra long spring to exert enough tension to keep the 3xAAA pack in place as it's shorte...

Re: Front light using AAs or similar...

I have a Busch+Muller Ixon IQ and it's superb. Runs off 4xAAs, lasts 2-4 hours on full beam and a lot longer on low power. Powerful and sturdy enough to not only get me through the Exmouth Exodus in hammering rain but to also have half a dozen other riders sitting on my wheel while descending Chedd...

Re: Front light using AAs or similar...

Ones like the Hope Vision come up, http://www.hopetech.com/product/1-led-light/ Could be suitable. I like this "1 x Cree XTE LED lamp giving 300 (215 measured) lumens" :roll: Yes, I found that amusing! With similar honesty (if that's what it is) in some of those chinese lights it would be...

Re: Front light using AAs or similar...

If a dyno hub and a hefty front light is not enough, I can only assume you plan to descend those mountains full tilt. In that case, I'm guessing you are looking for off-road type power. A google for off road lights might be your answer. Ones like the Hope Vision come up, http://www.hopetech.com/pro...
