RIP

As always, a lot of bitching and no action. If you feel so strongly about it why don’t you quit your job and go be a nurse. The hours are long and the pay is bad. Forget about buying a new bike again and you will probably miss a lot off races as you will have to work a couple of weekends a month. Or alternatively put in leave and go feed some babies, change bed pans, after awhile you should get use to the 12 hour shifts. The doctors are not striking and still the patients die? Patients dieing is a hospital management/government failure. The Government now want nurses to work back 4 years after studying. Taking in account that they work while studying so I assume even less people will studying nursing in future.

If they can’t find a way to make the road safer they are wasting there time. I don’t see that happening so will not bother to take out a licence again or do races.

38t is the smallest you can go on a 130 BCD. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Compact are usually 50/36 or 50/34. Campy front derailers have a 16 t capacity so a 52/36 should work. I used a normal FD with out problems on a compact. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> You don't need the 52 as you can make up the speed by dropping one tooth on the smallest sprocket. See pic. Here is a nice tool to see what difference the gearing makes: http://sheldonbrown.com/gears/index.html Ox_Wagon2010-02-11 10:32:49

It will depend on the frame you?re looking at. Some full sussers are designed for 80mm forks. The rule off thumb is that you will steepen the head tube angle with 1 degree for every 20mm that you drop in travel. The effect is that the 100mm frame with a 80mm fork will be a ?bit? more ?twitch? (steer faster). So look at the head tube angle of the frame your looking at. Most are around 69-71 degrees. Hardtails are normally 71 degrees. So it should not be a problem if the frame you?re looking at has a head tube angle of 69-70 degrees. Only a Giant Anthem can get away with a 72 degree head tube. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I build up an old Kona that feels like it steers slowly(wide) compared to my hardtail. I later found out that it should have an 80mm fork instead of a 100mm fork that it has now.

From a previous thread: Paraffin may cause problems. So cleaning the disk may solve the problem. Someone at the 24hr recommended Car Disk brake cleaner. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Ox_Wagon2010-01-13 08:02:55

Found it: http://www.beyondbikes.com/items.asp?Bc=Magura&Cc=05DTFORK Bummer, will be cheaper to buy a new fork. Ox_Wagon2009-12-17 06:09:00

Looks like it could be more complicated:http://www.support-english.magura.com/index.php?s=70b217a776ca23c8c519b9d681b138ca&showtopic=2404&pid=7877&st=0&&do=findComment&comment=7877 Some more links http://www.chainreactioncycles.com/Models.aspx?ModelID=16630 http://www.cheapbikeparts360.com/products/magura-asdlo-remote-lockout-kit/ http://www.chainreactioncycles.com/Models.aspx?ModelID=43063 http://www.actionsports.de/product_info.php?refID=idealo&products_id=17526

Kyk onder "Product features" en "Downloads"

OOPS, got it wrong. Looks like it has some kind of dynamic lock-out like the Fox F100X. More like RS Floodgate. There is a remote version. http://www.magura.com/en/products/suspension-forks-2010/prod/durin-race-8.html Ox_Wagon2009-12-17 05:41:57

So how does it compare to the alu version?

It explains that horrendous squeaking noise I been experiencing. Some one mentioned disk brake cleaner that you can buy at car spares shops. Would it work? <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Our team almost had a fist fight over who was going to ride the single speed next. Ride was great fun. I thought the fight was over how will next sacrifice their drive train to the bog fairies to see if the new/newer route is ride-able. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Talk about sacrifice, seams the road bike was spared the bone fire?? PS: Thanks again for allowing me to squat at your camp site.

The moment of inertia indicates the wheel?s resistance to change speed. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> A wheel with higher moment of inertia will take longer to accelerate on the other side will also take longer to slow down. It has the same effect as a flywheel. You want a light flywheel on a sport car to post low 0-100km times. (XC) In your bakkie, while towing your caravan (I am a ?bit? overweight), you want a heavier flywheel so that you don?t loss to much speed going over a rise in the road. (<?: prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Marathon)

Ok, as they say there is no rest for the wicked. <?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I had a look at the moment of inertia of the WTB Laser trail wheels. I assume some one has already spotted that I made a mistake comparing the Lazerdisk XC with the Lazerdisk Trail, will fix that. The results are a bit disturbing so please don?t allow sensitive viewers to see it. I really hoping I got it wrong. Using the simple I = mass x r2 formula. I get that the 29? wheels has around 43% higher inertia! This will explain why it feels like it keeps it speed better but will also not speed up as quickly as a 26?. This is good thing on a Marathon/24hr/Single speed bike and not so good on a XC race bike.

I decided to perpetrate some arm chair engineering?..<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> I started by see if it is possible to compare apple with apples. There is some interesting ?findings?. Firstly it seams the wheels are ?about? 12% heavier. It would be interesting to see what the effect is on inertia of the wheel? Thanks to <?: prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Santa Cruz?s site it was possible find that there is ?about? 10% increase (1.16kg) in weight for similar bikes. This translates to a whopping 1.34% weight increase for rider (skinny racer) and bike combined. Makes one think about all that money you want to spend to loose a few grams of your bike. The bike is not the problem?.. Finally I tried to quantify how much STATIC forward force is required to lift the front wheel over an obstacle. I looked at the moment where the wheel just lifts of ground and all the forces act on the edge of the obstacle. The force is calculated by determining the moments (caused by the weight on the front wheel and forward force) around this point. It is interesting to see that the % reduction is affected by the height of the obstacle. So just looking at this there is a small improvement using a 29er with an additional weight penalty. The inertia of the wheel may be a deciding factor (horses for courses). Ox_Wagon2009-12-04 07:41:44

I don't know if anybody has mentioned it be for.....<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Road motorcycle wheels: 17? front and rear Adventure toursers (on/off road): 19? front and 17? rear MX and enduro (off road): 21? front and 18? rear Maybe the MXers can shed some light on the preference for bigger wheels?.. PS: Golefty you can stop being so defensive ..... Cannondale DOES make a 29er now. http://www3.cannondale.com/bikes/10/cusa/model-0FS291S.html

This thread reminds me of the big 650b vs 700c (29er) debate over which is the beter wheel size for Triathlon bikes.

Kiwi (Planet X) has some.
