robster Posted April 25, 2008 Report Share Posted April 25, 2008 I am building a new bike up for Robbie over the next few weeks, the Hydroxx is simply just to much for him at his size.I do belive that all of this saving a bit here and there is a waste of time for most riders, however when you are 10 years old and 5 stone you need all the help you can get and bike strength is not as much an issue at the moment.What I would like to do is build something as light as his old Wasp, about 7.5kg. nice and short but with a full size back wheel in it. I would like some good ideas from all of you techi types out there as to how and what to use to make a really light bike for him. I have the frame but I don't want to let that out yet, drilling and cutting has started on the frame allready. All ideas welcome and remember there is no such thing as a stupid idea, go on have a bit of fun with this one and run with it.Thanks in advance,JP.

King C Posted April 25, 2008 Report Share Posted April 25, 2008 (edited) Just search for Tarty Adams bike pics topics, should give you quite alot of ideas.And the Hermance boxx one Edited April 25, 2008 by kcchan Quote Link to comment Share on other sites More sharing options...
Muel Posted April 25, 2008 Report Share Posted April 25, 2008 Dob frame + Fork.Try-All H hubs on Dob rims.Whats brakes does he want? Dual disc or disc/hs33?Monty TI cranks, he will be fine with them.TI Bar and stem, possibly a shorter stem?For the freewheel I'd get a Tensile, they are very cheap and work brilliantly, mine is over 1 year and 6 months old.Lightweight chain, as he is small enough not to snap it.Wellago MG-1 Magnesium pedals, they are pretty expensive but they do save a fair bit. (Echos, Onza hognesiums are all Wellago MG-1s).Your best bet is probably to ring up Adam at TartyBikes,as he has a lot of experience saving weight and will be able to tell you which direction to go in.

BenLeacock™ Posted April 25, 2008 Report Share Posted April 25, 2008 Im pritty sure that he will want double disk though ? Am i right JP ? Comps in wet might be abit poo with vee ? Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted April 25, 2008 Report Share Posted April 25, 2008 don't let ali C hear that...!vees are certainly no worse than maguras in comps.. Quote Link to comment Share on other sites More sharing options...
BenLeacock™ Posted April 25, 2008 Report Share Posted April 25, 2008 don't let ali C hear that...!vees are certainly no worse than maguras in comps..I was under the impression a wet vee = die ? Like no bite, hold or anything ? Quote Link to comment Share on other sites More sharing options...
Bionic Balls Posted April 25, 2008 Report Share Posted April 25, 2008 i'd say the hold on a vee is always more than a magura with the same setup...they go like maguras do...a bit...less good...! a grind is the answer..as with maguras Quote Link to comment Share on other sites More sharing options...
The Duck Posted April 25, 2008 Report Share Posted April 25, 2008 I have a bit of a love hate relationship with vees. Hold is pretty shit hot, but bite suxxx. Also your grind needs to be mega sharp for it to work well. I got shot of mine, very happy with maguras again now. Quote Link to comment Share on other sites More sharing options...

The Duck Posted April 25, 2008 Report Share Posted April 25, 2008 thanks lads, frame change not an option.So this DOB thing (whatever they are is not an option)JPOk, defo DOB rims if hes going to be running disks. They grind up badly though but as hes so light it might not matter an awful lot? Quote Link to comment Share on other sites More sharing options...
eskimo Posted April 25, 2008 Report Share Posted April 25, 2008 I have a bit of a love hate relationship with vees. Hold is pretty shit hot, but bite suxxx. Also your grind needs to be mega sharp for it to work well. I got shot of mine, very happy with maguras again now.My front vee is nuts! I'm still on the same grind with Plaz CRVs.Anyhoo, i'm guessing not too much money is wanting to be spent? I also think he has a strong advantage over us for weight saving due to his lightness as well. So titanium parts out of the question then?Alloy bolts and nipples ALL round, goes without saying. But unless you do everything it's not worth it i'd say.Radial lacing for rim brake. Radial on non-drive side of rear.Shorter parts; bars, stem, cranks etc. As he is small anyway, put performance over weight though.See if you can pull off a smaller gear. Like 16t freewheel up front? He has less leg power... Maybe a light rear freehub 10t with 15t fixed up front with no bash? Also means less chain..KMC Kool SL. Obvious?Non painted/ finished parts.Then just lighter parts.

Ashley Smith Posted April 25, 2008 Report Share Posted April 25, 2008 sounds like the frame needs a severe amount of material taking off like i did to waynes, strip the paint then anodise Quote Link to comment Share on other sites More sharing options...

ogre Posted April 25, 2008 Report Share Posted April 25, 2008 why you listing specs, buy a dremel. remove metal from the botom bracket yoke, the seat tube, the headtube + you could probably get away with a bit of toptube remember, circles + rounded edges = less stress.make the holes in rims wider, or square remove some sidewalldrill the cranks.remove the paint from the framedrill/cut down the bash ring/platedrill the pedalsTI axlesfile the magura mounts off if you use a diskdrill brake leversmake the rims singlewallalloy bolts + nipples Quote Link to comment Share on other sites More sharing options...
robster Posted April 26, 2008 Author Report Share Posted April 26, 2008 I have been busy grinding, milling and chopping away at work this morning, stupid thing is I forgot to weigh the frame before I started :$ Any how, off to shot blasting today all being well to take the powder coating off, then annodising, then build.Thanks for the ideas so far I will be putting some if not all into practice.John.
