These days when we buy bikes we're pretty concerned about the WEIGHT of our bikes.

Some of us, will put a few accessories on the bike after buying, I was very very surprised by the TOTAL weight of all my accessories 1650g+ = 3.6 Lb's+ (Wirless computer, Full water bottle in cage, mini pump in bracket, alloy bar ends ski type, and my heavy front halogen light).

Typical essential accessories and their weights (Specific to my bike parts, so look yours up in a manual/website, or weigh yours if you want something other then approximate):
~ a wireless computer (Approx 50g),
~ some clipless pedals (Instead of flat pedals, weight differences negligible, pair of pedals 450g to 500g approx)
~ water bottle & cage (Full with liquid about 450 g),
~ maybe some bar ends (150 g),
~ maybe pump & clip (150 g),
~ upgrade to disc brakes (60g, Total addition of F&R caliper & rotor, instead of V Brakes)
~ mudguards (Crud Catcher F 74g's + R 137 g's = 211 g's),
and perhaps some LIGHTS. There many different light styles, weights differ alot, For example:
~ my REAR led light inc batteries 40 G's, which is typical is pretty light, and
~ my FRONT high power halogen with seperate battery weighs a total of 850 G's, which is at the absolute heaviest end of the scale.

Depending of your accessories, you may have made your bike heavier by upto 2000 G's = 2 KG's = 4.4 LB's ! Surprising isn't it. For WEIGHT CONVERTER see HERE

Hence discussion of light weights below.

CONVENTIONAL LIGHTS with AA or AAA batteries:
OK the AA and AAA lights at night are visible to motorists, but offroad BRIGHTNESS is poor, you can't see where you are going, only people can see the light, but these lights are LIGHTWEIGHT.

RECHARGEABLE LIGHTS with integrated battery:
Some are more LIGHTWEIGHT then others (New version of mine weighs 230g, very impressive!). The BRIGHTNESS even offroad at night is excellent, even at speed.

Have a look at the newer range of mine:
http://www.niterider.com/rechargeable-new/
The newer versions are far more expensive then previous versions, the newer model of mine is 4 times the cost at RRP £240
http://www.wiggle.co.uk/niterider-minew ... ont-light/

My rechargeable front light with seperate battery (NiteRider RoadRat) looks like this:
Image

My older version is a great light, however it is a bit big, and a bit heavy

NiteRider Roadrat Halogen rechargeable Light:
Weight: 850g (Lamp, bracket and battery)
Bulb: Halogen 100w 6v
Battery: 6 Volt 6 Amp
Recharge time: 9 hour (I just leave it to charge overnight).
Run time: 2hrs 30 mins (My actual run time 1hr 30mins)
Cost: RRP £60 (Discounted to less)

Image Image


However there are many products I don't think alot of, and many of which we believe is inferior, only one example springs to mind, is a bike Dynamo:

BIKE DYNAMO!
Image

Well I never seen a Dynamo shine very brightly!

ADEQUACY OF PARTS/CABLE?
The dynamo thumbwheel creates alot of friction, on the tyre wall, slowing the rider down, reducing momentum, and wearing tyres more rapidly (As long as the cable is zip tied in place should be ok, but cable is typically thin, hence longlivety is an issue, and loose/sagging cable may snag on objects, especially if used offroad.

OVERCHARGE?
There is no battery storage: The cyclist needs to ride the bike to generate power the light (Hence no overcharge).

UNDERCHARGE/FLAT?
Since most dynamo's need the bike to be ridden to generate elec, then the light won't be useable when the bike is static.

Pap. My light uses AA batteries and delivers 205 lumens which lights up a good distance and is easily bright enough for off road. I used to run Vistalite 510s which had a bottle battery and this one torch out performs those. On 2xAA batteries you get the following from the Fenix LD20 -

- General Mode: 5 lumens (100hrs) - 30 lumens (15hrs) - 91 lumens (5.9hr) - SOS
- Turbo Mode: 205 lumens (2hrs) - Strobe

The Fenix LD20 is a TORCH though?

http://www.dryburghcycles.co.uk/product ... Light.html

Have you cobbled this to your handlebar? Or does it come with a bracket? Surely the long length of this torch, would make it ackward for offroad trail riding (i.e. You might knee it or headbutt whilst jumping).

Still to come from Srands::

Classics such as..............

Handlebar grips, is your rubber too rubbery? (are white grips really lighter?)

Pedals, remove bearings for a maintenance free experience

Saddles, who needs them anyway?

Frames, who needs them anyway??

How many more stoopid threads can you create?

If you're riding correctly your knees or head should be nowhere near your handlebars ;)

For lights one of the best cheap options is the 900 lumen Magicshine Cycle Light from Deal Extreme

http://www.dealextreme.com/p/ha-iii-ssc ... -set-25149

There is also a 1400 lumen version

http://www.dealextreme.com/p/ssc-p7-2-x ... uded-36018

If you want a British built self contained light then the USE Exposure range is very high quality and does not give hot spots like the DX lightsets

I have an Exposure MaXX D Mk4 with 1200 Lumens, it's more than bright enough for any trails no matter how dark it is

http://www.exposurelights.com/product/0 ... xx-d-mk.4/

Then there's the UK light builder Troutie (from STW forum) who is making his own lightsets with excellent results

Don't know why anybody bothers posting serious answers to this guy's posts, he's either a troll or a complete fruitloop.
As a troll he's a failure, so think I'll go for fruitloop.

Enid, I think he has a never-ending capacity to write pointless crap about any subject. Just so happens he's chosen a bike forum. :wink:

My personal favourite was "Mountain Bike Receipts - Friend or Foe?"

Although the one about wall plugs plumbed new depths of tedium!

FFS!

'Sno worth it. 8) :lol:

Thought he was a troll at first but his lack of response to the piss-taking replies gives me the impression he's genuine but has 'issues'. :arrow: :?

Well most decent lights are not cheap, especially those that work in Offroad areas so you can see without the aid of any street lights.

900 lumen Magicshine
The 900 lumen Magicshine Cycle Light is pretty cheap at $60 Euro's = £53, but it's still NOT light:
Weight of Light: 640g = 1.4 lb's

http://www.dealextreme.com/p/ha-iii-ssc ... -set-25149

NiteRider RoadRat: Older type
My light the older version NiteRider RoadRat, is even heavier:
Weight of Light: 850g = 1.9 lb's
Image
Image

NiteRider RoadRat: Newer type
The newer range of my NiteRider RoadRat are far more expensive then previous versions, it is 4 times the cost at RRP £240, but it is alot lighter:
Weight of Light: 485g = 1.07 lb's
http://www.niterider.com/rechargeable-new/
http://www.wiggle.co.uk/niterider-minew ... ont-light/

Anyway folks for rechargeable lights with a designated battery, Ah, the larger that is the greater the capacity, hence the longer running time duration.

For example with a 100w bulb the battery is:
6 Volt 6Ah

If the same bulb (100w) was used with a larger battery:
6 Volt 8Ah, then the CHARGE TIME would be longer, and the RUNNING TIME would ALSO be longer!

Also my knees and head do get near my handlebars, when jumping of course.
