Cruzbike Recommendation: SR, Q451 or Q559
Hi Rich,
The Quests are more versatile than the Sofrider, at least in gearing & stopping -- 3 x 9 + disc brakes front & rear. You can add/change these components later on the Sofrider (the front disc is just a bolt on, while you'll have to make/get a rear brake mounting bracket), but the seat is higher on the SR & you can't do anything about that without major frame mods.
Since you're concerned about shorter riders, the Quests would be preferable. [personal opinion] The problem with the Q451 is the lack of tire sizes. The largest size available is 1 3/8. I've got some Maxxis Holy Rollers (20 x 1 3/8) on my wife's Q451 v1. They're quite nice as an all-around tire, performing reasonably well on both paved roads & gravel trails.
I ride a Q559 v1 (modified into a Q29er -- 700c x 37) as my daily commuter. I also ride an older Sofrider V1 with 26 x 2.3 Kenda K-rads in the winter, but only when the roads are not snow-covered or icy (I live in Idaho). All the bikes will handle fenders, but normally fenders limit your tire choices (except for the Q451, where you'll have lots of room).
The roads in Idaho are not as smooth as in regions with milder climates, so I really like having suspension in addition to fatter tires. I've put a Cane Creek Cloud Nine air shock on the back of the Sofrider, so it is possible to tune out most of the chip-seal vibration. Further, I've put on a front disk brake & converted the drivetrain to 3 x 9. The front fork has a little more suspension travel than the Quest V1's & a lot more than the V2's, since they have a rigid fork now.
I like the riding position of the Quests more than the Sofrider. The 'cockpit' seems more open & the handlebars are not so close. The BB is higher on the Quests, also. However, all the bikes are very comfortable. I setup all my bike seats to have the 45 seatback angle of the Silvio. This seems to be a pretty good tradeoff between visibility in traffic & good aerodynamics. The new component upgrades on the V2 Quests are quite nice & may justify the price difference. I've found the short chainstays on the Q451 to be a problem for my wide feet & hitting the rear derailleur while pedaling, unless my heels are splayed out. I've tried some 10mm pedal extenders, which help, but the solution I prefer is to use the longer chainstay yoke from the Q559. I'm 6' 2", so the telescoping top tube is extended a lot.
Here are some measurements to peruse (all the bikes are set up for a 47" X-seam):
model handlebar height seat height BB height notes
Sofrider v2.2 45 (to ctr) 26 1/2 23 1/2 w/ stock 26 x 1.5 tires
Quest 29er v1 47 26 26 w/ 700c x 37 tires
Quest 451 v1 41 5/8 22 19 1/2 w/ 20 x 1 3/8 tires & long chainstay
Have you ridden a MBB bike yet? If not, perhaps we could set something up. My son will be going back to Corvallis for school later this summer, which will give me an excuse to include Oregon City in our travel plans I'd bring the Q451. Or, if you want to take a vacation to Yellowstone, I'm on the way (Idaho Falls, ID) & you could ride all 3. What's your timeframe?
