    I have the Reverb on my Reign. Done about 500kms of riding with it and no issues at all. It's great to be able to drop your seat at will.

    I got the left hand mount for the remote and put it in upside down on the right to protect it.

    I wouldn't say that about BIKE magazine(Bicycling - yes). They received three CB Kronolog posts. One had a failure, that CB covered under warranty. They, also, reported exactly what failed in that post (it was a part that wasn't to tolerances; not a design issue). What they had to say about the Specialized Command Post is exactly what I've experienced (finicky cable attachment that can fail).

    I don't believe everything I read, either. However, with the cost of these posts, I'd be willing to trust a reputable mag, whose testers ride a lot more and are exposed to a lot more product than I, than I'd trust opinions of forum members. Not being smart, here. It's just that I have a tendency to trust a pool of riders who've seen all the stuff out there and have a collective experience that rivals what you're going to find here.

    Yeah I hear ya, I should add I have a pretty big attachment to my LBS... they have been phenonmenal with everything the last year or so, and I'd really prefer to give them business than go elsewhere. That probably explains my preference to go with the Giant Post than the others.

    No harm. But, when it comes to something like this, which has very limited appeal, I tend to look elsewhere for info. We don't have a huge MTB community, so listening to what some of our shops say is like asking someone on the street for MTB help. BTW, your LBS can get anything available, as I'm sure they order through QBP (Quality Bike Parts). You can use the flip catalog to find the part numbers of what you're after. Dropper posts start here.

    4+ inches of drop, but you did have to remove a hand from the handlebar. Adds maybe 3 oz to the bike. No play/lost motion and any failure won't stick you in the low position.

    the fun part about that QPB onine catalog is finding stuff. :huh clue, go to the LAST page (the >| icon on the bottom), then go BACKWARDS through the pages, the index is on the right margin of the right page. this years catalog, the clothing and accessories section is a lovely pale yellow on light green, almost impossible to read at normal size on my 24" computer monitor, but a half dozen pages before that, the regular components index starts, and its got a orange background and is at semi-readable. once you find a page number, like 333 for cranksets, then type that number into the page number field in the middle bottom and hit Enter, and voila, there you are. click on something to zoom, click again to unzoom, left/right or pageup/pagedown to flip through. :evil

    Anyone know a bit about bottom brackets?

    Been having issues with mine and realised spinning the pedals loosens them. I thought that was supposed to tighten them?

    Maybe my bike was assembled backwards!

    I had to tighten the bb again and now it is binding. Maybe it is too wide and bottoming on the cups?

    I could get another bb but I would like a set and forget model next time around.

    what sort of BB is it? loose ball and cone, square post cranks? you need a spanner and a pin wrench to adjust those properly. a bike shop should have everything they need to do it, on your own, its kinda tricky to get just right.

    frankly, if a square post loose ball and cone BB is giving you trouble, I'd replace it with a $25 Shimano UN26 or whatever, needs to be the right length but otherwise, its just plug and play. one side you install a cup that you grease and screw in all the way, then slip in the BB, then the other side is a lock ring, grease it if its metal, but don't grease it if its plastic, and you screw it in fairly tight, the bearings are sealed and preset so they can't loosen up. then grease the posts and install the cranks. oh yeah, you need a BB tool and a crank puller to do that job too, but a LBS should do it for like $30 or something.

    It is square spindle. I have the tools and have swapped once. I wiped some of the grease out and cranked it very snug this evening but it is definitely catching on the metal screw in lock screw or whatever it is called.

    I don't have a pin wrench or spanner. The special toothed socket, the combination crank puller tool, and a big adjustable wrench.

    Looking at the different designs, a lot of them come with a thread lock on the threads.

    I will get another new one, clean the threads, and dab some light grade thread lock on the threads and reinstall with less force this time.

    Grease leaked out of the threads of current bb.

    is it a sealed bearing cartridge, or a loose ball and cone thing in there now?

    a loose one is like this...

    [​IMG]

    but thats a really /nice/ one from the early/mid 80s. with those, you have to set the cones just right so they are smooth, and this takes the pin spanner and whatever to adjust and tighten. the end on the top left is installed on the drive side, and torqued down (lightly grease the threads first, then put the bearings on the axle, heavily grease them, then insert the axle, and put the other piece on the far right on the non-drive side. the NDS cap has a lock ring, and you need to loosen the lock ring, adjust the inside piece to the bearing is just so, then tighten the lock ring. if it binds, redo it backing out the inner piece a hair. rinse repeat and it shoudl be good for /years/

    if you have a cartridge bearing, its important to clean the threads thoroughly... grease the metal on metal threads but if the keeper ring on the other side is plastic, do NOT grease it. you insert the BB tool into that ring and torque it on pretty good (specs in Shimano lit here...

    says 50-70 N*m, or 7-10 ft-lbs.

    if the ends of the bottom bracket hanger on your frame aren't smooth and parallel, they won't seat right. a decent bike shop has a tool for facing the ends so they ARE parallel and square

    I agree; provides hours of entertainment.

    Yeah, WTF were they thinking? The contrast makes the index nearly useless.

    Just got in from not quite 2hrs with 2 x 3-lap 'cross races' around my local park.

    That's on top of yesterday's 3:40 or so up and down the hills between my house, Rectortown, Marshall, and Warrenton.

    Ugh are my legs tired.

    Need some advice from the very experienced and knowledgeable riders here.
    I was not real happy with the owner of the Specialized LBS, we have 3 LBS within 1/2 blocks of each other. I went to the Giant LBS to look at some cold weather riding pants. I was on my GSA which has a very distinct paint job and it is street only parking. The older gentleman working commented how he had seen my GSA at the other bike shop and politely asked why I had never shopped with him. I told him I came to the store back in the summer when I was looking to buy a bike but the young man working at the time seemed to have no time for my novice questions and ignored me returning to his conversations who I assumed was his riding buddies. He shook his head and apologized and stated I was the fourth or fifth person he has talked to telling the same general story and he had let that person go about a month ago just for that reason. He said I am the owner and would like to welcome you to the store and showed me his selection of cold weather riding pants. I found a pair of pants I liked and he discounted them 20% I continued to look around. We talked a little and I shared with him my interest in wanting to get a road bike. He said I can make you a great deal on a left over 2012 55.5 Giant Defy Composite 3 cash/check price $1,100 + tax he also said he would take my 2013 Crosstrail in on trade if I wanted to do that but would have to look at it before he could give me a price. I can test ride it anytime but it did not feel bad sitting on it in the store.
    This seems like a lot of bike for a good price but again I am still a cycling noob just wanted some advice Pros Cons or other thoughts before going in for a test ride...

    Craiger, you can get a lot of bike on the used market too. 1100 plus tax for carbon frame and tiagra drive train is OK. Nashbar has a full carbon road bike that has no decals but comes with better components for a similar price plus they do sales constantly and no tax if you are out of state.

    Also consider what you may want to do with the bike. Longer rides and you may want something with built in rack mounts.

    WOW Nashbar just made my head spin... The problem with Nashbar for me is I don't know the components or have enough experience to know what I would be ordering... I just started cycling this summer and had not had a bike since my Schwinn Varsity ten speed 30 years ago. I bought my Hybrid not knowing what type or even if I would like cycling. I needed to find a physical activity I might enjoy and the last few months I have been cycling an avg. 5 or 6 days a week, I am cycling 12 to 17 miles per ride through the week and on weekend rides I have been doing 15 to 25 mile days trying to build my base fitness. I have been road riding in and around town with the occasional trip to the bike trail. Saturday was to be my first fitness test as my goal was to try and do 50 miles Saturday but I had the eggbeater collapse again 10.5 miles into my ride. With 95% of my miles on the road I figured I might like a road bike better than my hybrid for how I have been riding. Just for reference I am 6' 3" 228lbs with a 32" inseam I wondered if I was a little big for a composite bike but the bike shop owner assured me the bike would handle my size....

    plus, you don't get the fitting expertise of your LBS, and you are either going to have to pay them or setup the bike yourself. most LBSs include a 90 day tuneup with a new bike where they tighten all the stuff that loosens up, retrue the wheels (new wheels often loosen up a bit after the first few 100 miles), readjust the derailleurs, etc. this isn't a big deal for someone experienced, but for a relative novice its worth it.

    My Trek Superlfly 100 has been plagued with persistent problems when downshifting under power. The SRAM X9 seems to work flawlessly when the bike is suspended from a stand, but the minute I take it out on the trails and downshift, it either doesn't shift gears at all, or it will shift seconds later, accompanied by a nasty grinding sound. In some instances, it suddenly popped into another gear even when no gearshift has been initiated. Oddly enough, shifting to higher gears goes very smoothly and predictably; I can't recall a single instance in which it has failed to up-shift. I've brought the bike into the Trek store repeatedly, and each time they 'fix' it, it will work for maybe one trail ride, and then begins malfunctioning again. Yesterday the excuse I got was that dirt from the trails may be causing it, yet none of my three other mountain bikes ever exhibited this problem when ridden on the very same trails. :scratch

    At this point I'm inclined to think the X9 unit is defective. It's still under warranty, yet the dealership has been very reluctant to replace it with a new one. The shifter on the handlebar has already been replaced, but that didn't solve the problem, so whatever is going wrong seems to be further down the line. Can anyone suggest what else might be causing this before I pressure the dealership for a replacement?
