    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

    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...

    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

    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...

    weighty subject

    A Sofrider V1 weighs 34 lbs. on a calibrated shipping scale. I have a conversion that weighs (or weighed, before I took it apart to "improve" it) 31 lbs, but it's far from a conventional conversion. If you look at a selection of conventional SWB recumbents using steel or aluminum frames, the...

    Noisy rear shock adsorber

    Some gap is normal in the side-to-side direction because the shock has no role in side-to-side location of the rear suspension. The shifter feels "tighter" when shifting against the derailleur return spring; it's lighter when shifting with it. Since the SRV2 uses a "low normal" derailleur...

    deraileur mounting question please

    Hi Bob, You need the screw and plate show with this derailleur hanger: http://www.loosescrews.com/index.cgi?d=single&c=Derailleur&sc=Rear%20Hanger&tc=&item_id=LS-1701PD&id=137338019978 This will allow you to move the axle in the axle slot as needed and won't require you to drill and tap the...

    Confessions of the Cranks

    Bob, Actually... you usually need a crank puller to remove the cranks and frequently a bottom bracket tool to remove the bottom bracket. At $30, it was a wash...

    torque values for Silvio construction

    The fasteners on the Silvio are generic stainless steel fasteners. In some cases they thread into aluminum. Usually a good rule of thumb is to tighten them with a standard-length allen wrench until they are as tight as you can comfortably get them (e.g. you are not bending the wrench). Bear in...

    Bike rack

    Hi, I think you'll be fine with either one. The seat is a little wider than a DF seat, but not so much as to interfere with the back window or the other bike. The V1 and V2 are very compatible with anything that works with traditional MTB's - that's one of the great things about the Sofrider...

    ATTACK!

    Well, my friend, Glad you are okay. Reminds me of what we used to see on the back of a fellow's race car - "Old age and treachery will always defeat youth and skill." He was 76 when he won has last National Championship in SCCA. Really messes with them when you beat them in a defensive...

    trek y-22 for donor? Picture included

    Hi Randy, Normally I'd warn you about seat height, but based on the position of your seat in the picture, you're probably pretty tall. You can relax the rear shock to bring the crossbar height down some. My principal concern is with the seat bracket digging into the carbon fiber. The Cruzbike...

    Showing off @ LBS...

    Bwaahaaa! Well done, Marc.... I've decided to delve back into my kit bikes. I really like the freedom to try stuff with the kit; you can really build anything you want with it. As much as I love my red kit bike, I think I will disassemble it and try something new. We have a newly-opened bike...

    Silvio Newcomer

    Hi Pattrick, Welcome and please feel free to post any questions you might have. I'm not a high-performance rider; I can tell you my Silvio climbs better than any other recumbent I have ridden (and there are 14 recumbents in my garage right now). As for height issues, we've got those handled...
