Okay I have two questions for you all wise, all knowing monkies.


First.

I seemed to have stripped the pedal threadson my RF prodigy DH cranks (right side) Now, is there anyway i could drill out the threads, press in a steel insert, and tap it again without compromising Strength?


Or should I get some FSA V-drives from go-ride for 60 bucks and throw away my old cranks? and will they work with my RF bb?

I weigh 195, the cranks will be going on my new Titan hardtail, which will be used for N* and such. Maybe some DJ's thrown in.

Hardly seems worth the effort when you could just replace the crankset for cheap. An RF ISIS bb will work with the V drive and or other ISIS crankset like Hussefelts, Holzfellers, RF Northshores, etc. just make sure you aren't getting the FSA external bb V drive crankset if you want to use your current bb.

Go to a good bike shop. Wheels Manufacturing makes an insert that installs from the backside to repair pedal threads. This is your quick and easy fix. Don't waste your money on those v-drives. You'll strip those out in less than a season.

I see new Hussefelt cranksets on Ebay all the time for less than $70

I'd avoid Hussefelts at all costs. The V-drives are cheaper and last longer. I've had great luck with mine.

Buildyourown has the right idea on the crank savers, though, if that's your inclination.

Personally, I'd buy the v-drives, send the old cranks to RF if they're under warranty, and then keep the replacements as a spare or sell them for the price you paid for the v-drives.

Yeah, the bushing installation is a pretty cheap way of getting that fixed.

I disagree about the V-drives though, I weigh 205 and have used mine for 2 seasons of Ex. DH racing, drops, etc, broken both frames that the cranks were on, and they're still going strong. On the other hand, they don't have the greatest reputation so I may be a really lucky one...

The v-drives are great as long as your not a big guy and not changing pedals a lot. Soft alloy cranks like the v-drives and hussefelts are my pet peeve. I switch between clips and flats a lot and seem to destroy weak pedal threads.

I would do this, But I talked to thge Raceface warrenty guy, and he said the don't warenty cranks that have the pedal threads strip out.

Did you go though a shop. I warrantied a pair of square tapers that got F'ed up cause they were ridden loose. (I let a friend borrow my bike)
They claim that they don't warranty cranks for that either.

Sorry, I want some GOOD cranks this time.


And no, I didn't by them through a shop, I got them from a fellow monkey a few weeks ago.

easy fix, purchase the correct size and thread pitch helicoil insert, drill out old threads and press in the helicoil. I'm sure a machine shop would do this for a minimal charge.

Where would I buy one of these inserts?

You should be able to find a shop with a helicoil/recoil kit for pedal threads, takes a few mins to tap out the thread (no need to drill it bigger), screw in the thread insert with a bit of locking compound (I use superglue, dodgy but works), and then run a thread tap through that to clean it up... put the pedal back in and away you go. I'm suprised that not every shop has such a kit handy, it makes a whole lot of sense to do those sort of repairs to help customers out on the cheap.

If you're a bigger guy (195 is decent size I think) I agree with BYO...avoid the VF's. They are way too soft and will bend, break on you prematurely. Chainwhip was about your size when he bent the heck out of his.
