    Girvin Spring

    I recently bought a Girvin Vector girder fork from ebay and was wondering if anyone had some advice on swapping in a spring instead buying new polyurethane or an expensive coilover conversion kit. I have an old mountain bike rear coilover shock with a 750 lb/in spring in it, but I'd rather just...

    flip a girvin fork

    I just picked one up on ebay and after studying it for a while, it occurs to me that flipping it won't change the trail as much as it first appears. Think of the place where the lower links connect to the fork legs as a pivot point. While you're moving the axle forward, you're also tilting the...

    Mongoose Beast Fat Bike build and ideas

    Thanks for the links to your fork and bike builds on the other thread. You ironed out the main wrinkles that make this bike less desirable. For the record, I liked the Stainless Steel color you had it painted in the video too. MHF

    Mongoose Beast Fat Bike build and ideas

    @ Uncle Stretch.......either that's a different/custom frame, or it's highly modified. Either way, could you share some details please ?....especially about the fork !

    ....Springer Fork

    Nice design and well executed. I especially like the "dogbone style" links. You've designed a simple, clean and I'm sure stiffer fork by using those links.

    ....Springer Fork

    Ok, maybe the word "dummy was a bit harsh in describing the little v-twin, but I intend to make it up to you with this post..... This design is absolutely brilliant. It also made me do a double take and study it. At first I didn't see how it could provide any suspension but I see it now and it's...

    ....Springer Fork

    Maybe it's just because I want one so bad, but I have to think if someone would tool up to produce something like this @ 49cc and sold it for $300 or less, they'd have plenty of orders. I once had a Ryobi string trimmer that had a small 4 stroke with exposed pushrod tubes, removable cylinder and...

    ....Springer Fork

    Ok, thought you'd found the holy grail of bicycle engines there......tiny little 4-stroke, 45 degree v-twin with exposed pushrods and intake ports between the V. I was about to beg you for info on it, but on closer inspection it's a dummy....cute but non-functional. MHF

    modern board track racer, special design by me

    Is anyone going to bring up the subject of trail before this guy hurts himself ? jj256, please read the page on this link and the few that follow. The rake and trail (or lack of it) you're building into this project is potentially very dangerous. Pedal powered bicycles might get away with it...

    Kent Bicycles Customer Service

    Some time back I was reading through a thread on the Genesis Onyx 29er and there was some information on contacting Kent Bicycles customer service department. The information was in response to someone's worry over not being able to buy parts for it. There was a name and email address for a...

    Felt on a 29er

    mrfritz on Thu Jun 07, 2012 6:37 am Venice Motor Works sells the forks with disk brake drop outs as well as the drop outs by themselves. There is a new HD version of both. http://venicemotorbikes.com/store/produ ... acad2cf462 That's the Monark style fork, but thanks for looking...

    Felt on a 29er

    I just bought Genesis Onex (Onyx?) 29. Does anyone know if a Felt Abraham springer will fit ? The tire size and steerer tube length are my main concern. I also bought a set of rims from a Genesis 29er MTB to get the front disc and 36 spokes, so I'm hoping someone makes a disc friendly rocker...
