    Quick maintenance question. Since I'ma sissy I spend most of (all) my time on the middle chain ring. The middle ring accumulates a ton of dirt, but it's hard to clean because the big ring is in the way. As I was pondering that today, I noticed that the big ring appears to be held on by 5 simple hex bolts (Specialized Secteur with Shimano parts). Can I just pull that big ring off to clean the middle ring? If so, what torque shoudl I use when I put it back on? Hell, as long as I'm asking, does the middle ring come off too? The middle ring actually appears to be the base of the whole thing, so I'm not sure it will come off.

    Thanks,

    They're all replaceable. I just use a brush and dish soap on mine. I only tear the bike down about once/year. That includes new cable/housings, new bar tape, and pulling the crank. Tires, chains, rings, and cassettes are replaced as needed, but rings and cassettes last a LONG time if you keep a tight chain on there.

    In short, yes, you can pull the rings off.

    I've narrowed it down to 'earth'. Or 'Baltimore'.
    Hey, how many traffic laws are there?

    SOP - south of Phoenix, hotter n hell
    FM to tears. We started the 600k on Saturday morning at 0500 and made it to the high point of the ride, Beaumont CA late that night - lots of climbing but some beautiful areas. It was first hotter than hell - over 100F - and then, it turned cold. On the way out of Beaumont, we missed a turn and ended up 20 miles from our control.

    In SoCal, that's a killer. We went down two routes - one ended up being a dirt bike path and the other was blocked by construction. Imagine, riding like madmen streets trying to find Iowa & University in RIverside? We made it with less than two minutes to spare and then started back to the hotel where we ended the first 400k with a 36 minute cushion. The goal was to have a 5 hr cushion which we would have had w/o the missed turn. The mileage total after 26 hours was 275 miles.

    I told my partner that we had to watch our time - I suggested that we take the 36 minutes and combine that with 30 min from the next control to give us an hour to regroup, eat, put on fresh clothes and hit the road. He wanted to lay down for 20 minutes. :huh That put us 30 minutes late or effectively, we lost an hour out of the next control.

    When we finally hit the road, we were making great time on the bike path - 16-20 mph but when we hit the PCH, my partner....died. He couldn't go over 12-14 mph as we made our way towards Huntington Beach, Laguna, etc. We hit the control in Dana Point with three minutes to spare and then he decided he wanted to eat. :lol3 He was doing 7 mph up the hills - that's where we lost our time.

    FMTT - I'd dying here - we have to get to the next control in Dana Point and my partner, due to no sleep in the previous 27 hours, can't ride fast enough to make the controls. I took off from DP and thought, maybe I can throw down a challenge and he'll follow me. So, I take off on the PCH at 20 mph and.....nothing.

    I get to San Clemente and wait for him - and wait...and wait. I finally see him coming down the road and he's doing maybe 12 mph.

    OK - we have 20 miles to go and one hour to get there - "can you make it?"

    He responded, "I'm done". That ended our ride - we had 325 miles OR 520 km. The goal was 372 miles or 600 km.

    As the title states, "close but no cigar".

    As usual, my glass is half-full. We did 325 miles - was up well over 35 hours w/o sleep - braved a lot of SoCal drivers who did great for the most part - rode some nice bikeways - saw a few drunks and police playing games at 0200 - and learned a lot of lessons.

    It's all good! We'll attempt another 600k next month in southern Utah and if I can't finish that one, the goal of a 1200 is off the table for 2012. Between now and then, I'll attempt to climb South Mt as much as possible to get stronger on the hills.

    Two more questions. I want to pull the cranks off so I can clean all around inside that area. I also want to pull the rear wheel apart so I can clean the cassette and all the associated hardware. My Park Tool Bicycle Repair Book is a little vague on which tools I need. I have a 2010 Specialized Secteur with low-end Shimano parts. Any idea which tools I need to pull the cranks and separate the rear wheel?

    Thanks,

    Jim Moore

    there's a bunch of different ways cranks can be attached nowdays, used to be, all decent bikes used square taper cranks. frankly, I wouldn't pull the cranks for cleaning, if you don't get them back on just right, they can creak and will drive you nuts.

    taking the sprocket off the rear wheel, I usually just bring the wheel to my friendly neighborhood bike shop and let them pop it off for me :)

    to do it yourself, you need the correct fcassette tool for your wheel, and a bench vise. you put the tool in the vise, and put the wheel on the tool and turn the wheel to break the lockring and then unscrew it, and take the cassette off.


    instead of taking this stuff off the bike, I suggest getting a couple parts cleaner brushes with fairly long plastic bristles, and a spray bottle filled with kerosene or wd40, hose stuff down, brush off dirt, repeat. do this where its OK to make a greasy mess, like over a big drip tray.

    Da UP, eh.

    Sounds like you maybe just need a stronger partner. :dunno

    Although I know how damn hard that can be finding somebody that:
    a) is willing to ride crazy distances
    and
    b) is closely enough matched to your abilities

    and well... I haven't gotten that far yet, but I suspect this one's important to:
    c) is somebody you're willing to put up with for 24+ hours when neither of you are at your peak of social grace. :lol3

    I haven't ridden my fixed gear in about a year, due in part for the reason mentioned above. I never did get my square taper cranks back on just right so, yes, they creaked, but that was the least of my worries. One of the nuts would occasionally become so loose, almost to the point of falling out, that the pedal end of the crank arm had about 2cm of lateral play. I don't carry an allen key big enough with me on rides, so there wasn't much I could do in the middle of a ride except for using my fingers to tighten, which would do the job for only another mile or so. Back at home, I'd tighten the bejeezus out of the thing, but the same scenario would eventually happen again.

    So, what's the trick to getting the cranks on 'just right'? (square tapered, specifically)

    take both cranks off, clean everything really(!) good (especially the inside of the cranks), use a thin coating of clean green waterproof bearing grease on the square shaft, and torque the bolt down to 28 ft-lbs.

    Sounds like you could've made it if you hadn't stopped for your partner.

    There's gotta be a 'if I'm not gonna make it, you go ahead' decision made beforehand. Then stick to it. UNLESS its a medical emergency that is.

    Onya for getting 3x as far as I've ever ridden on a bicycle in a day. :clap You rando types are nucking futs!

    Since you've ridden it loose, you may've screwed the pooch on this one. :nod Riding the crank with that much play may have ruined the taper inside the crankarm.

    Clean it, reinstall it (grease vs no grease is a big religious argument, BTW) and hope. If it does it again, new cranks.

    We're slow but steady. I need to get a little stronger on the hills and may look at a cycleops rear hub to get a better idea on managing my (what little there is) power output. My partner is probably a little stronger than me - in fact, I suspect he's a lot stronger. He just can't manage w/o sleep.

    It may get to the point where we made a decision as you suggested i.e. "you go, I can't go" but this is our first year and we've kind of made a commitment to stay together as we do these rides. I still feel pretty good about the events since we have learned a lot of valuable lessons so we're not quite there yet.

    Thanks for the kind words - these are great events.

    Like Gummee said, if you've wallered it out - time for a new set of cranks. However - and especially on fixed gear - it's hard to keep 'em tight. Mine started doing that, loosening on every ride - and I HAD the wrench with, so If I would snug it any time i noticed or would check during the ride. Granted, every time it loosens damage is done. But I had a wild idea - cleaned the tapers well and reinstalled using blue locktite on the mating surfaces. No more problems. Worth a try.
