$60.00 | | Purchased At: | pricepoint | | Strengths: | This was a true set it and forget product for me. No dropped chains, full range of gears, stealthy looks, great price. | | Weaknesses: | The roller is noisy, but I've come to enjoy it as it lets me know when I'm not pedalling hard enough. Also, it's only noticeable on hills and fireroads. | | Similar Products Used: | None | | Bike Setup: | IH SGS, 7x7, basically a burly FR bike with a granny gear. I set the Guide up with RF North Shore cranks and a Truvativ Gigapipe BB | | Bottom Line: | I agree with other posters that the directions are useless, but if you have a basic understanding of what this chain guide is intended for, you should be able to set it up quickly. For what I paid for it, I figured the guide could be a throw away because chainrings and a bashguard should cost more than $60, but the guide has been great. I would buy it again at retail when/if the time comes. Right now I'm planning to put the Dewlie on my Heckler and get a DS-1 for my Iron Horse. | | Value Rating:Overall Rating: |

$60.00 | | Purchased At: | pricepoint | | Strengths: | It keeps the chain on. | | Weaknesses: | The chain guide is fairly easy to mount. The directions however are completely useless. They have one set of directions for ALL of their guides which is no help for the Dewlie. The design of the guide is poor. The inner plate is almost the same diameter as the bash guard. Thus when you bash hard the inner plate takes the hit as well which can cause it to move. The roller is not wide enough. With the front in the granny the chain will bear on the roller. And this is with the correct bottom bracket setup. | | Similar Products Used: | First chain guide so take my review with a grain of salt. | | Bike Setup: | Specialized Enduro Comp 130 2005, modified so it doesnt break. | | Bottom Line: | The guide does not guide adequately for my bike. I tried everything including flipping the roller around and I find it lacking mechanically. | Value Rating: Overall Rating: |

$60.00 | | Purchased At: | Ebay | | Strengths: | Great guide, never drops a chain. Relativly light weight. The replacement rollers are cheap, but I havent had to buy one yet. The roller bearings stand up great to the mud that we get here in the Pacific North-West. Alot cheaper that a E-13 DRS, with the same performance. | | Weaknesses: | A little difficult to mount on my bike. Blackspire web-site is pretty much useless. | | Similar Products Used: | E-13 DRS, Truvative Box-Guide (peice of crap!), MRP (overpriced) and a dual-bash set-up | | Bike Setup: | 2004 Kona Stinky, Kona glow-in-the-dark grips, Kona DH Primo handlebars and stem, Vanilla RC, 66, Single-Track rims on Hadley Hubs, Truvative Hussefelt cranks, Blackspire Ring-God bash guard Kenda Negeval 2.5' tires | | Bottom Line: | Go out and buy this product right now! I have hucked this thing on boulders, logs, rock-gardens, drops, jump, step-up, step-downs, hips, road gaps, you name it. This thing has never dropped a chain. It seemed with the DRS, everytime I came close to bottoming in the rear, I would drop my chain into the granny, or even worse, into the bottom-bracket holder. This is most likely to the chain lenght shrinkage as the shock compresess on my Stinky. Now anymore though, as soon as I set this thing up, I never dropped a chain. This product is so light that I dont even notice it, except for when I charge a rock-garden that I used to drop my chain in all the time, and make it out unscathed. When I pedal up-hill there is no rubbing and the pedals slide as effortlessly as before.
If you havent bought this product already, then there must be something terribly, terribly wrong! | | Value Rating:Overall Rating: |

If you want a great double ring device, buy blackspire. I'm sure it has its flaws, but none that i have found/ had problems with. | | Value Rating:Overall Rating: |

Smooth. | | Weaknesses: | Exposed and unreinforced pulley! | | Bike Setup: | '03 Norco Shore with some extra goodies, now running an Evil DRS | | Bottom Line: | 2nd day on the Shore (after a one year layaway payoff) and I slid left off a log to flat landing of about two feet. Chain grabbed when exiting and I looked down to see the pulley and inner plate bent up causing a complete failure of the retention system. Had to remove the pulley system to even pedal.
Catastrophic engineering flaw in my eyes having the pulley as large, exposed and unreinforced as it is: just one small bolt/axle. | Value Rating: Overall Rating: |

bending.
| | Weaknesses: | None that I can see. It does what it is supposed to do. | | Similar Products Used: | None | | Bike Setup: | rocky Mountain team | | Bottom Line: | This thing woeks great. I had some trouble at the outset
getting the right bb, which caused me all kinds of grief.
The inner plate goes under the bb shell, and it put the chainline outboard, so the chain was always trying to derail. I found this out at the bike shop. They put in an e type bb from tru vativ, and it fixed the problem. Funny thing what not reading the instuctions will do for you.
I would buy this agian and have rec'd it to friends. | | Value Rating:Overall Rating: |

I don't know what the issue is that previous reviewers have had with throwing the chain off while backpedaling. I don't backpedal a lot, mostly when I'm ratcheting the cranks to make sure I'm in the right position to climb over some obstacle, but I've NEVER had it toss the chain while riding. I actually went out and rode the thing for a day and TRIED to get it to throw the chain while backpedaling and it WOULD NOT! Maybe I'm just lucky that my chainline is just right or maybe I didn't try hard enuf... (Don't think so...) LOL!
I've also never smacked the roller or its mounting tab. The REST of the inside plate and outside bashring have more than their share of scars, but the roller is still rolling along in one, unbashed piece.
Maybe this product isn't a perfect fit or spec for every bike, but it works exactly like the best products in the world on my bike: I don't even remember that it's there! Can't get much better than that! | | Value Rating:Overall Rating: |

Date Reviewed: October 2, 2003 | | Favorite Trail: | Too many | | Duration Product Used: | 6 months | | Strengths: | Keeps the chain on most times | | Weaknesses: | If you do any urban stuff the little roller gets bashed into the object you bash ... instead fo the bash ring. | | Similar Products Used: | none | | Bike Setup: | Norco VPS Shore 2003 .. mostly stock except for Chris King Headset, Easton Monkey lite bars, Raceface Diabolus seatpost | | Bottom Line: | This is a pretty good product. I have had similar issue with it as the guy below me when backpedaling, though it is not happening to me withthat much frequency. Actually almost never when I ride. Most when I stop and the pedal goes backwards. Maybe I just don't backpedal enuff when I ride, I dunno, but it doesn't seem as severe. Also when I am doing urban type stuff where balance is and issue and I backpedal, I tend to be in the granny.
My major beef is with the roller bashing up on stuff when I try to get up on a 2-3 foot ledge. Instead of the bashring taking it, the roller gets it first ... so beware of that. I t is still in good shape despite a lot of wacks so it doesn't seem to be much a prob.
value wise .. dunno it came on my bike ... so not too sure. But over all I would say 3-4 chillys ... | | Value Rating:Overall Rating: |

Date Reviewed: September 25, 2003 | | Duration Product Used: | 6 months | | Bottom Line: | To follow up on my previous posts, I contacted Norco about my difficulties with this product since Black Spire offered absolutely no help. And they recommended that I simply flip the roller around, which temporarily solves the chain dropping problem but greatly compromises the chain line while in the granny ring, adding friction and a steep chain angle over the roller. I received a very poor response from Black Spire when i asked for help with their product. All I can say is buyer beware and this seems to be a common theme with much of there products. Hope you have a fix for next year. Cheers. | | Value Rating:Overall Rating: |

Date Reviewed: June 23, 2003 | | Duration Product Used: | Less than 1 month | | Purchased At: | Mountian Magic | | Strengths: | keeps chain tensioned | | Weaknesses: | nothing if you only pedal forward.... | | Similar Products Used: | none | | Bike Setup: | Stock 2003 Norco Shore | | Bottom Line: | The bottom line is this product is great if you only pedal forward. Half a pedal stroke backwards and the chain falls off the top ring and down onto the granny. This happens in 2/3rds of the gear combinations in the top ring. In the middle of a long log ride 20ft in the air this can be very dangerous. I challenge anyone to get their chain to stay on while back pedaling. After emailing the Blackspire Dewlie guys for help on why this is happening I realized it is simply poor engineering and simply a poor product. I’m looking at buying the Evil dual chain guide which has obviously addressed and solved this problem. Secondly I’m ashamed that Norco and Blackspire Dewlie have suckered me into buying such a poorly tested product. Shame on you!! If anyone feels I’m out of line please email me with comments. | | Value Rating:Overall Rating: |

Date Reviewed: June 22, 2003 | | Duration Product Used: | Tested or demo'ed only | | Purchased At: | LBS | | Strengths: | Keeps chain from getting stuck between granny and frame | | Bike Setup: | Stock 2003 Norco Shore | | Bottom Line: | ah...maybe I don't have this setup properly and if anyone disagrees PLEASE help and respond to my email address. This was my first ride on my new shore…and the bike is great, but this chain tension thing is not working so well. It tends to keep the chain in place when riding on the bumps, but in certain gear combinations the chain falls off constantly. I don’t know about everyone else but I tend to back pedal a half stroke here and there to setup for stunts and drops. This usually happens when I’m in the big ring and the upper gears in the back. Since the derailleur has moved the opposite direction to the big ring it will pull off the chain down to the granny in one revolution. For my style of riding this product is complete junk. Sorry Blackspire Dewlie, kudos on trying…but the lack of testing is quite obvious here, better luck next time. | | Value Rating:Overall Rating: |

$125.00 | | Purchased At: | Edmonds Cycle (B.C.) | | Strengths: | Does all it says it will. Chain no longer clanks around on my stays and so far zero chain hopping. I was having a brutal time with my chain falling off, not being in the right gear, and smacking down on the front derailleur and stays. No more of that! | | Weaknesses: | I've never used a guide system before so I don't know if this is normal or if I installed it poorly but it buzzes in certain gears from the chain lightly rubbing the guide wheel. I actually like the buzz except for when I'm riding around campus. | | Similar Products Used: | none | | Bike Setup: | RM7, North Shore cranks, XT everything else. | | Bottom Line: | I was surprised with the ease of installing the Dewlie and really have no regrets with it so far. It wasn't cheap, but to me it is incredibly more worthwhile than a standard guide system. I pedal just as much up hill (steeeep) as I do down on a normal day so I need two rings. Solid product that does all it's supposed to and it looks badass! | | Value Rating:Overall Rating: |
