Anyone put disc brakes on a V-Rex?

Before trying something as involved as a disc conversion, try a brake booster. -- John Foltz --- O _ Baron --- _O _ V-Rex 24 --- _\\/\-%) _________(_)`=()___________________(_)= (_)_____ |

Anyone have any advise or experience adding disc brakes to a V-Rex Like John said, it's a very involved conversion. You'll need a frambuilder to fabricate tabs for the caliper mounts, a paint job to follow, and new hubs and rebuilt wheels over and above the purchasing the disk brake hardware. I can't see getting away from the shop for less than $500. Five hundred bucks buys some darn good caliper brakes. In addition to John's suggestion of a brake booster, I'd try replacing the brake shoes with Kool-Stop salmon colored units: http://harriscyclery.net/site/page.c...=49&SKU=BR1226 . The salmon-colored shoes are the choice of bike couriers here in Portland. They've worked fine for my commuter bike, too. Jeff |

Anyone put disc brakes on a V-Rex?
I just had a ceramic rim and pads put on the rear of my Vision R-50. My LBS
did the all the assembly. This cost me about $165. This was probably about $30 - $40 more than a standard rim. My experience on my road bike has been very good. They give better stopping power in both wet and dry conditions. They don't seem to fade in wet weather. They seem to hold up well in long downhill descents. If you are about ready to switch out rims for any reason you might inquire with your LBS and see what they have to say. I was going through rims about every 4000 miles on my road bike and mountain bike. Even with cleaning the rims every night when I got home. (Riding year round I pick up a lot of grit and the brakes have to work a little harder to stop 225 + lb.s of me and gear.) I put 2000 miles on my road bike after installing the ceramic rims and pads. They show very little wear at this time. They showed me a set of rims that had about 10,000 on them and they still looked very good. "John Foltz" wrote in message ...

Anyone put disc brakes on a V-Rex?
It is a metal or composite arched plate that mounts to the brake studs via
a longer set of screws through the brakes' pivots. It will resist flexing of the chain stays or fork legs as the brake pads apply force to the rim and cause a torque moment about the mounts. The booster improves braking by making the frame/brake mount stiffer. I use a booster on the rear brake of my V-REX. "Bobinator" wrote in message om... I put a rear disc on mine.

A brake booster is a horseshoe-shaped device which attaches to the canti posts. Its purpose is to prevent the stays from bowing out when the brakes are applied. This is especially useful on RANS bikes, which use relatively small diameter tubing for the stays. Preventing the stays from deflecting makes more pressure available on the rim, with obvious benefit to braking power. Brake boosters can cost as much as $50USD, but if you watch for deals they can be had for $5. -- John Foltz --- O _ Baron --- _O _ V-Rex 24 --- _\\/\-%) _________(_)`=()___________________(_)= (_)_____ |
