    so I've got a flatbar road bike (hybrid) that has 3x8 trigger shifting, and I'm thinking of converting it to a 2x9 or 2x10... i've been doing Shimano stuff for awhile, but I'm thinking maybe I should give Sram a try... I see on their website a Via GT and Via Centro gruppo of nearly exactly what I want, targetting city and trekking bikes, but I don't see those available online anywheres.
    http://www.sram.com/sram/urban/products/via-gt

    Whats the budget Sram road group I should use? A mix of Apex and S-series? I'm gonna need cranks (50-34 or 48-32 or so), shifters, cassette and derailleurs for this... and probably new wheels too (I assume I can't put a 9 or 10 speed cassette on a 8 speed freehub, eh? anyways, I eventually want to get nicer rims). The mountain groups all seem to have tiny front sprockets...

    Those Via groupsets are new, to me. I've been looking at putting a 2X10 MTB (42/28) crankset on my 'cross. The Via crankset might be the way to go. Hmmm.

    Give these guys a call, about the Via groupsets. They can quickly pull it up and give you a price.

    I think S-series/Apex mix will be about the most budget-friendly way to go.

    We currently run Apex (48/34 with 12-32, for me, and 46/38 with 12-36, for her) on both our bikes. It's solid, reliable stuff. We really like it. Both our MTBs are SRAM, too.

    Damn... beat me to it! I just watched this from a friend's link and was just astounded! What makes it even more epic is that the bike he is riding is from the TdF winner Bradley Wiggins. :huh

    hmm, I don't see the Via stuff in QBP's 2012 catalog at all.

    etc etc.

    so, yeah, must be TOO new. ah well, I'm probably a year out from doing this upgrade.

    Reminds me of the time I got SIX speeding tickets on the ride from Cardiff to London. I didn't pay a single one of them, but I wonder how much the total would have come to. :evil

    Are Shimano freehubs and SRAM cassettes fully interchangable, even in 10sp ?

    do 10 speed cassettes fit on a 8 speed freehub ?

    You *may* need a spacer behind the 10sp cassette, but those're easy to come by.

    edited to add: as long as you're talking about Hyperglide cassettes and not Uniglide cassettes

    "Gummee!" is correct, on the spacer. If the back of the cassette "spider" is flat, you'll need it. Otherwise, the "spider" will have a raised lip around the center hole, which eliminates the need for a spacer. If in doubt, your LBS can make a quick assessment.

    I'm very bad about taking pictures during brevets. Luckily, John Lee Ellis was kind enough to post a few from the Last Chance 1200. From JLE,

    The wet beginning. I'm on the far left and my buddy David is next to me:

    The last turn before the finish line - three of us rode the last 35 miles together.

    Now I know what 1200 km/750 miles in 85 hours feels like. I was damn happy to be out of my cycling shoes too.

    and... wheels.

    WE7256 Handspun Pavement Series 5 Rear Wheel 700c 36h Shimano LX / Mavic A319 / DT Champion All Silver
    WE7254 Handspun Pavement Series 5 Front Wheel 700c 36h Shimano LX / Mavic A319

    (the number is QBP's PN).. those look to be a $200 'touring' wheelset. near as I can tell, Handspun is a QBP house brand for machine made wheels with a range of decent components, obviously these are at the lower end, but last I heard, Deore LX was OK stuff, as are Mavic rims (the A319 are a pinned 6106 alloy box 622x19 rim, recommended for 28 to 47mm tires, so my target range of 32-35mm should be fine... and if I get skinny and start riding farther, I can even put 28s on them).


    thinking about something like this as an upgrade to my hybrid (which has noname rims and hubs), along with eventually switching from the crappy 3x8 alivio/acera/whatever to a sram apex compact 2x10... yes, I know, this ends up costing like $600

    this is hte crankset I'm looking at. can be had as cheap as $116 or so, with an english thread BB.

    Well after 7 years of doing absolutely nothing as far as exercising. I have decided to get the mountain bike out and air the tyres up and try riding. I started last Thursday. I rode 10 miles and had 2 heart attacks a few coronaries and I'm not sure but I believe that I gave birth some where in there. It took me 1 hr and 51mins to ride 10 miles on flat ground. Skipped a day and road 10 miles on Saturday. not to bad I shaved it down to 1 hr and 10 mins and felt ok, besides the muscle burn and knee pain. I road 10 miles Monday and stayed in high gear the entire time with no stops forgot to carry a watch so I don't know how long it took. And it wasn't that bad at all. The only problem is my knees feel like they have ice picks jammed in them during and after. I know that the body posistion and seat height have a lot to do with this. I made sure the when my leg is in the fully extended position that it has a slight bend in it. But what else could I do or do I need to just keep pedaling and it will go away. Answers:ear

    drop the seat another 1/2" or so. stay in a lower gear so you're pedaling faster but easier, that requires more wind but less grunt, and less strain on your knees.

    if that old mtn bike has knobbies on it, and you're mostly riding on bike trails and occasional hard pack, get some slicks or semi-slicks in like 26x1.75 instead of gnarlies in x2.125 or whatever you got now. for mostly pavement, run the tire pressure up near the max and it will roll easier. oh and clean and lube the chain..

    I'll try lowering the seat, the bike does have knobbies on it, I have aired the tyres up to the max and lubed the chain and sprockets. When I bought the bike I didn't know crap about bike riding other than the 1982 to 1990 years while waiting to turn 16 and completely lost interest in riding because I couldn't take chics out. But I figure since I was a large frame I would need a 26in frame. From what I see now I think I should have around a 19in

    That is a SOLID wheelset if they are built well.

    LX is great stuff and A319's are good tough rims.

    This would be a pretty typical budget (but still good) wheel for a loaded tourer around 200lbs rider weight.

    frame geometry has changed considerably since the classic bike days. in the 70s/80s, you wanted the tallest frame you could barely straddle for a road bike, and maybe 2-3" shorter for a pre-suspension mountain bike. with a 34" inseam, yeah a 26 or 27" frame would have been typical in a road bike. I am 6' tall, have 32" inseam, and rode a 24" road bike frame.

    now days, the seattube length is less important, its really the top tube length that counts, and you want that sized to your torso... you can adjust for your leg length with the seat post, and your arm length with the stem and bar rise.. with those numbers, I'd say you're a L to XL bike in most lines.

    if you do get a new mountain bike, look for a '29er' (29" wheels, really 700c mountain bike wheels), these are much better suited for big guys. if you're going to be mostly riding bike paths and occasional hard pack, a hybrid might be the way to go, and if you're going to get serious about speed and long distances, a full out road bike.

    i'm back down to 210 lbs after being weighed in at 230 a few months ago, this is my 'hybrid' trail eater.
