Not exactly all trials but here goes - 1989 to present day Repco Skyline (fully rigid) Giant Sedona SE (XC) DBR Zetec (XC) DBR V-Link (Duallie) DBR V-10 (Freeride) Kojima Hawk (Road) Recumbent 3 wheeler with drum brakes and internal hub (home built) Specialized Stumpjumper (15" pub bike) Schwinn Homegrown Factory (XC) Schwinn Fastback (Road) Saracen MAD 2SixH (snapped) Planet X Ali Bongo - sweet.

You better make the effort Monkey Nuts. If you're not there I WILL hunt you down.

Thats your garden? Nice work! Where can I get some reels like that?

I've not used the veggies but have heard they are good. I use the Planet X plain black ones (they also come in camo which look anything but - be ok if you wear jeans). I rate them and they are good value for money but the only problem is the hard plastic insert is flat so it doesnt exactly fit around your shin. Solution: unstitch the top of the pocket where the insert slides in, put it in a tray if hot/boiling water for a few seconds, whip it out and bend it around to shape. Do this a few times, and stick it back in. 5 velcro straps so pretty comfy.

Titanium is great structurally because it has a high strength/weight ratio. It has a strength less than that of steel but weighs a lot less. Therefore the benefits are that you can build something the same size and achieve the same strength overall but will weigh less. Ti also has other excellent properties like resistance to corrosion and fatigue as well as a high melting point. Great for bike frames, engine parts etc. Since we're talking about freehubs which will be the same size (take up the same volume by design) if they are steel, titanium or peanut butter, the strength of the steel one will be higher. You would need to make a Ti hub much bigger to achieve the same strength as steel. Also, the toughness - resistance to impact - is lower than steel which is probably why the body on BIGA1's freehub is being compromised. I would imagine the cassette is steel. I see the only advantage of Ti in a freehub as being weight reduction but this is so close to the rotational mass centre that it would make very little difference. Hope that makes sense.

Incorrect. It has a much better strength to weight ratio (than steel) but pound for pound it is not as strong or tough.

For all the Canon users that have Zoombrowser it also does batch reductions.

Got a time in mind?

Not feeling too bad apart from being in a meeting all day. I'll be there between 6.30-7. On a PX Ali Bongo, Black and White. Yellow lid.

You asking if the time and place is any good or about my riding? Yes to the first No to the second but am keen to get out with some locals. Thats of course if i'm mobile after a 20kg piece of steel fell onto me from a roof. If I can ride at all i'll prob come along and bring the camera.

El-timo and El-placo?

Started at 32 on a Saracen 2Six, snapped it, now on an Ali Bongo and 33.

I agree with tank_rider, get back to basics. The abuse a trials bike gets from a rigid frame and dynamic loading could be quite ambitious so i'd suggest a static analysis. You could say apply a load through the dropouts and isolate each section ie triangle and determine the stress in each member (tube). Then perhaps compare this with a standard road bike or MTB frame geometry and say why you need to make a trials frame stronger. eg gussets, CNC'd sections. As you said, by moving the a connection 20mm should show some good results once you have the initial model set up. Then you could discuss frame advances over the years like fluid forming and tube shapes etc to reduce problems associated with welding zones.

If you like riding in the heat, humidty and rain then take it. It rains pretty much every day and the humidity is so high you sweat buckets just walking around - not to mention the chafing . It can really sap you. I cant speak for all of Singa and i've not ridden there but I would imagine all the cool lines would be in built up areas which are generally jam packed with locals and tourists. You dont see too many high end bikes in Singa or very many serious riders on the street like other countries. If you're just going for a visit i'd suggest leaving the bike at home, soak up some local culture and eat yourself into oblivion - the food is amazing and cheap!

I was asked to leave Temple Quay near Bristol Station over the weekend. I know a few of you ride there - has any one else had this? Its was a security guard who was quite polite and said I couldnt ride there because it was private property so I left quietly and respectfully. I cant see how it is anti social either. Generally we have a good name for ourselves and arent out to cause damage or drop into crowded areas. I think theres an element of 'fun police' with most complaints - people either exercising authority for the sake of it or who are messed up enough in their own lives to go out of their way to stop other people having fun.

How old is that frame? By the sound of it its been around a while. Good news since i've recently built up a PX Ali Bongo.

Not being a proud owner of an angle grinder (and I was on a budget at the time) I couldnt do a grind. So I took a leaf out of the book of aftermarket rotors for cars etc and put shallow slots in the front with a file and just ran a sharp blade across the rear. The idea is to stop glazing of the pads and to provide a bit more bite. Works a treat in both respects. Bike rides really nicely. Its built from parts from my Snapacen and a few upgrades. Way easier to hold on the rear wheel. As for the seat, I dont run one when doing trials and run a full post and seat when I ride it to work!.

I changed my Maggie rear to Avid SD7 throughout, no grind, no booster. Only a tiny bit spongier but way grippier. 2 thumbs up for cable V's and will prob change the front out soon. Nice.
