Trek Mountain bike question for techs
I have a 5600(?) mountain bike. My son wanted me raise the handle
bars and I couldn't. The shaft from the front forks go up only so far - and there's two donut spacers that go right on the shaft. While disassembling this I also noticed that shaft is loose and moves forward and aft like it's loose. There's a split washer that fits into the frame tube but that only goes so far - you'd think it'd go in further to stop the shaft from wiggling. So how to stop this shaft from wiggling? Am I missing something here? Should I take into the shop for a taller handle bar shaft? What a stupid design - not being able to tighten the stirring shaft to the forks! Any advice? Thanks JaKe Seattle |

I use the latter, and it's a cheap fast fix, if a little ugly. |

I dunno, some shops might charge you a twenty to tighten up a headset, my LBS would probably replace a stem on the spot and tighten the headset for free, if you bought the stem there. That's if it wasn't busy. It's really easy to tighten up a threadless stem. You just need to set the bearing preload with the hex bolt on top of the stem with the stem clamp loose, then, when the slop is taken out, you tighten the clamp. It's dead simple. You don't need to press in any cups or seat any crown races (both which are easy as well), just replace stem as needed to raise or put on a stem raiser. Five minutes--unless you go too far and need to put in longer cables. |

If you need a much-higher position for the handlebars, you'll have to replace brake & gear cables, because they won't be long enough. That can add up to a fair amount of expense in itself. But you might be able to get an inch or two of added height without changing cables. All that would require is a stem with more "rise" to it (the part going out from the bike would have a steeper angle than the stock one). A stem itself might cost $25 or so, and if you buy it from the shop you got the bike, it's quite possible they won't charge for installation. Otherwise it's a pretty simple job that someone might charge $5 for. --Mike-- Chain Reaction Bicycles www.ChainReactionBicycles.com "jkdrummer" wrote in message ps.com...

Thanks JaKe Seattle You've already gotten pretty good advice from other posters. If you do need shop advice, I can recommend a shop if you give me a general location in Seattle. I'm in the Central District, right near the I-90 tunnel entrance. -- Dane Buson - "We take your bags and send them in all directions." -In a Copenhagen airline ticket office |
