    hats off to john, jim and doug

    Thanks for your encouragement, Chuck, I am reminded of two quotes: "Nobody cares as much about your [stuff] as much as you do." "The cutting edge is where all the bleeding occurs." We'll keep keeping on. Thanks for chiming in. Best, Doug

    necessary to have fork backwards?

    Hi There, Turning the fork around serves several purposes: 1. It moves the forlk legs back to allow room for the cassette while expanding the axle clearance from 100 to 135mm, 2. It restores the steering geometry's original rake/trail relationship, keeping the bike stable, 3. And as you...

    Correcting misinformation about wheel discs that I started

    Hello Folks, I'll be blogging later about lessons we learned abouth the Silvio during Maria's incredible performance in the 12-hour. But first I must correct a misdiagnosis I made prior to having all facts in hand. During a nutrient handoff at about midway through the event, Maria had a nasty...

    Seat Back help

    Hi Rod, Try moving the seat back cushion up so it sits slightly higher than the top of the seat back pan. This will relieve any pressure point you might feel there. Works very well on my Silvio. Best, Doug

    Conversion Kit Assembly questions, fork adapter

    Hi Jim, You're dealing with a couple of things here. Typical front axle diameter = 9mm. Bolt that fastens the triangle adapter to the fork = 3/8 inch (roughly 9.5 mm) You'll need to open the front dropout a little with a file, then the bolt will fit fine. Bolt into triangle adapter hole...

    The Scottish Conversion

    Hi Currystomper, Looks like you could put another axle nut on the inside, use it to snug up the spacer, and come out about right... Let us know how you go... Best, Doug

    Wider may be better. And how about mismatched sizes?

    We list 700c x 28mm as the largest recommended tire size for the Silvio. These pictures are of a 700c x 28 tire mounted in a Silvio fork: The crown clearance is a little over 3mm. It should be remembered that actual tire dimensions for different manufacturers under the same nominal size...

    I just got beat up on the internet.

    The issue with rims and high pressure tires is that frequently single-wall rims can spread open under tire pressures of 100 psi or more and release the tire bead. The tube then escapes and encounters the frame or brake and BLAMMO! This is why these bikes are usually delivered with tires with max...

    I just got beat up on the internet.

    You can always find an expert. The tough part is finding someone who knows what they're talking about.

    Just bought the kit...have a few questions

    Hi Jim, Not a bad frame design, particularly if you have a 32" inseam. Is it steel or aluminum? My rule of thumb for seat height has been to make it at least 2 to 3" less than my inseam. This allows you to plant your feet and have more confidence leaving from a stop in traffic. I have to...

    Illinois Avalon

    Excellent bike, Rod. These are proving to be good donor bikes. 2 trips and 31 miles is great progress. Any MTB-compatible trainer will work; the load cell will probably wind up behind the front wheel underneath you. Well done. Doug

    Installing Triple Crankset/9 Speed Cassette on Sofrider

    Hi Rome, Your current front derailleur will work fine. The SRAM left shifter should shift it okay. You may need to adjust the derailleur height in the mount depending on your top ring tooth count. What chainrings do you expect to use, and what crank length are you considering? Lemme know what...

    Hardtail questions.

    Hi ebonetta, Hardtails work fine; I've built two and I think DefJack has built two also. The older Jamis Capri should work and convert to 26" wheels if you change the fork and rear brake: http://www.bikepedia.com/QuickBike/BikeSpecs.aspx?ItemID=92472&Type=bike Isn't the newer Capri 2.4 a 20"...

    New Convert

    Hi, This is what you want. If you can't find it, let me know, my LBS stocks them... http://www.origin-8.com/product_detail.php?short_code=Space&cl1=HANDLEBARS I have them on my SR Proto. Wide, right down angle, lots of knee clearance... Nice bike! Best, Doug

    Sofrider V2 700C Upgrades

    Hi Rome, I have done most of this in pieces, on multiple bikes. The SRv2 will accept 700c wheels very nicely. You will need a set of road calipers to install on the front fork and the rear swing arm, on the brake bridge provided. The cassette change is straightforward; I am using an SRAM...
