Ok so heres the situation. Took the bike to the bike shop, adjusted the wheel spacing, new front fork, RS Recon Race 08. Attach the wheel following these instructions to a T and finding that the discs are in a different position relative to the caliper and rub lightly, meaning I have to readjust everytime. Could it be the rotors? I had them tightened at the lbs. Will do some more experimentation and see if I can isolate the problem. parabola2008-11-01 16:04:35

Hi Guys I am looking for people to go riding with at Tokai/Jonkers/Anywhere in the Cape thats cool, either in the week/evenings or weekends. I stay in the area so I frequently visit the Tokai arboretum. I'm not looking for any particular age group, but I am looking to ride both longer cross-country rides with some trails inbetween. I'm a mellow 23yr old MSc student at UCT but I really am not too bothered who wants to join as long as you are a serious rider who's looking to have fun and push themselves.

Not a roadie but love the color scheme!

hi Vaulter can you explain how you have filled in the V-brake mounts on the fork? Looks quite interesting, I have a similar problem at the moment.

The Silverback alpine is an extremely nice bike for the price, well built and the Suntour XCM fork is much better than most other entry-level forks. Comes with a semi-decent wheelset and great tyres. V-brakes work well, and the drivetrain is a mix of shimano and SRAM components. Its quite a heavy bike but its sturdily built. I am refering to the 08 model (which was R2999 a while back) but I bet you could get one for a good price if you look around now that the 09 models are out.

Well done on choosing to maintain things yourself! But maybe its just me, but i think a decent bike shop would swop them for free assuming you bought the pads from them. Otherwise check their website for the appropriate maintenance guide. parabola2008-10-14 10:08:28

Thanks for all the help guys..

I have followed your method to the T previously and have had to repeat it everytime I put the wheel back on I have had them adjusted by a professional only to come home and put the wheel on, and same problem. will try the force method though and see if that helps., it is definetly related to the position of the shaft with regards to the dropout flanges. When you say "just make sure that everytime you re-install the wheel that the axle is flush with the dropouts." can you explain a bit further please Thanks for the responses, much appreciated

Technical question for you guys Im having trouble with my front disc brake, an avid juicy 5, being used with a shimano RM65 hub with a 180mm XTR rotor. The wheel skewers are the stock shimano ones. I find that I can get the brake calipers perfectly aligned, but as soon as I remove the front wheel, I need to readjust the caliper, and/or play with the quick-release for about 10 often futile minutes. I have found that the problem lies with the inner locating nut of the wheel skewer, the part that locates the inner edge of the shaft with the inner face of the fork. The nut is not round, and has flat edges so you can use a spanner to clamp onto it. if I orient the nut differently, the disc position changes significantly when I clamp down. so my question is - would buying new skewers help, or is there another cause of this that I can fix myself?

I would take the bolt with me to a place like bolt-it or topfast (in Cape Town) and show them. Also make sure you get stainless steel (316 preferably, otherwise 304) or they may rust.

I think that a major benefit is the instant shift times, as the gears are constantly meshed in a planetary gearbox, and the gear selection is done by merely locking different parts of the gear system. These kinds of gearing systems can give a huge speed selection without having a different sprocket for each speed. The chain does not move at all relative to the frame, which itself could lead to simpler and lighter bikes, as there can be less clearance between frame and chain. EDIT - its like having all the benefits of a single speed but with the flexibility of a variable speed transmission. An enclosed housing comes with real advantages on a machine used outdoors, most obviously they require less maintenance and will increase sprocket/chain life. The disadvantage is that they are usually complicated to service and do not lend themselves to trail side repairs. This is probably where I see bike transmission designs going in the future, with internal hub transmissions becoming the norm on the rear. But its going to take a while for the technology to develop to the point where it is both reliable and accessible. parabola2008-09-16 14:35:01

you could also try fingernail polish as a temporay cosmetic solution. If the scratches are deepish then smoothing over the area might weaken the tube wall. So you might get an enthusiastic panel beater who sands the frame smooth in an attempt to restore it.

Ive got some IRC Mythos XC's which are pretty fast/light/moderately priced, but I've got nothing to compare it to unfortunately. http://www.mtbr.com/cat/tires-and-wheels/Tire/irc/mythos-xc/PRD_353294_151crx.aspx

Hi guys I was checking out Chain Reaction and was wondering what the extra costs are, if any, over and above shipping? Is VAT at the PO paid at the usual rate, and do any import taxes apply? Thanks EDIT : As far as I know, import duties do not apply to bike parts, only complete bikes. So there would be no other charges other than what is paid to the retailing website? parabola2008-09-15 03:47:10
