I think cyanoacrylate (crazy glue) would work similarly and benefit from its capillary action. You could bolt everything up and then cement it. Sounds awfully permanent. Best,

Hi Mark, It's a 155mm crank length crankset. 52/39 would make the gain ratios really high. the 50t/36t matches the 155mm crank really nicely, giving adequate low and a "keep the legs moving " high for speedy downhills. best,

... or upgrade for Sofrider V1/Freerider... http://www.chucksbikes.com/store/cr044.htm

Hi Sean, John is referring to the fact that many of the bikes were shipped with the seat mounting bracket reversed. From the pictures it looks like yours is one of the backwards ones. The black seat mounting bracket needs to be turned around 180 degrees. Then the seat pan incline will be what...

Ahhh, all things become possible as batteries improve. Wonder if it works better than Mavic's electronic system that came out a few years ago? Combining Japan's bicycle and electronics dynasties could produce some amazing stuff! No doubt we'll see RF shifting control to replace all those...

Hey Mark, In the spirit of bike porn, show us your Trek frame! Jack, another good one! I think the unsuspended conversions are underrated. I have run pressures up to 90psi on the red bike and the ride is quite acceptable. Us tinkerers gotta stick together! Time for a flood of innovative...

Hi, How tall are you? What is your inseam measurement? Many of your questions can be answered extensively with that information. You'll need to add 1.5 inches to the standover height for most frames to estimate the seat pan height for a conversion bike. The conversion standover height needs...

Jack, Glad to find someone else who's bit by the building bug as badly as I am. good onya. Best,

Hi Jack, These photos are from the company website and show pretty much what we had in mind for ergonomics for the Freerider: Note that the headtube falls right about mid-thigh; this generally will not interfere with your pedalling even during a turn. If you are doing a really tight...

Hi Alan, As Mark says, you'll need one of these: The stem tube clamps over it. There are several solutions for the brake match-up. The brakes Mark listed work; they're also beautiful and unfortunately pricey; these will do the same thing for a little less money...

Well done, Alan. Sounds like you are picking the technique up quite rapidly. I believe the insert you are referring to is a short reinforcing tube provided for the fork steerer tube. If the steerer tube on your fork is thicker than typical, the insert may not fit. There are quite a few...

Hi Dan, The cog size question arises if you have the TFT adjusted to a very short length. This makes the chainstay-to-fork-leg angle very acute, and can allow the chain to rub the inside of the fork leg in top gear, especially when the chain lifts for shifting. The TFT on my Silvio is adjusted...

Jack should be able to chime in on this one - It's very much like the C-dale he converted - He seems very happy with it. Best,

Hi Jon, Very glad you weren't hurt. It sounds like you reacted very skillfully. Looks like the bike was hit on some pretty strong parts- I'm willing to bet the rest of the front end is okay. I'd turn it upside down and verify the wheel is straight, and then use the wheel as a tool to tell if...

Well, Doug, Seems you are working with a straightforward and up-front supplier; they really seem to have your best interests in mind. Single-wall rims are good for about 65 psi on average; any more and you start exploring whether the variation in rim weldling and extruding were on your side...

Hi Bravewave... I built my first conversion on a frame that is functionally identical to the one you're showing, although it was a Toys-r-Us steel bike and weighed a ton. As you can see, I used a different seat, but the comments about seat height are consistent with what I found. The...

Hi David, Thanks very much for letting me know the bike is working for you. I'm particularly pleased that your wife is enjoying the bike. Just hollar is there's anything else you need - there's quite a brain trust around here on these bikes. Any time you wanna chat about V-1 mods, just lemme...

Hello... Looks like a quite suitable frame. I've always liked the rear swing arms that arch over the bottom bracket; you can even remove the bottom bracket if you're careful! The steerer tube shouldn't be a problem. My assumption is the tube has a 25.4 mm outer diameter, which makes this a...

Hi again, Dave... The V2 actually uses the same size tires as the V1 - 1.50 x 26, but they are rated at 100 psi instead of 65 psi. Your tire choice is dictated by what type of riding you'll be doing. I have one of the Interbike display prototype V1's as my personal bike. I have 1.00 x 26...

Hi Dave, The Sofrider V1 uses a fork with a very long steerer tube. There is a "star-fangled nut" installed into the top of the tube, like any threadless headset would use. The adjustable stem that attaches to the steerer tube is a little unusual in that in addition to having two cinch bolts...
