Rated 5 out of 5 by tres bon produit Tres bon produit fonctionne sans bruit.... pas de problèmes d'installation sur DEMO 8 SPECIALIZED 08 April 2010
Rated 5 out of 5 by It works. Easy set up, compared to E13 DRS. Easier to keep running smoothly as roller is exposed rather than closed in as on DRS. Bigger roller bearings should last longer than DRS too. 23 June 2009
Rated 2 out of 5 by Works, but a pain to fit Good news first - when installed and set up it works well. Not noisy either. The not so good news - it was a pain to fit. BB type on Kona Coilair 2007. If assembled per instructions on a standard 50mm chain line set up, it puts the guide plate too close to the granny ring = chain rubs hard on guide plate. Exchange guide plate and BB spacer and it works out OK, within Blackspire's recommendations. BUT - then the chain does not sit well in the roller groove when on the (36t in this case) middle ring. Modified roller profile in lathe(!). Also the slider is way too wide and strikes the crank. Slider thickness reduced 5mm on milling machine. Slider bolts cut down in length to suit. Will depend on the bike, but for me, on this bike, it doesn't all compute. The value of the slider on a 36t ring is questionable. The slider remains a considerable distance from the front derailleur (Blackspire recommend 4mm,closest I can get is 40mm on this frame). Blackspire must have got something wrong here, if you assemble per instructions and don't swap spacer and guide plate, the roller and slider would be even further wrong. Conclusion - avoid if you're not prepared or equipped to modify parts to suit. You don't get a lot of hardware for your money. Not tried E-13, so can't say if better or worse. 07 June 2009
Rated 5 out of 5 by e13's are sold in the uk by silverfish. there's no mention of they're stuff on the silverfish website though. www.silverfish-uk.com 05 October 2004
Rated 2 out of 5 by Not bad, pretty noisy and well fiddly to set up. Flexes a bit too. A lot cheaper than an MRP but really, I wanna get hold of an e13. Would have bought an e13 but couldn't find anyone selling them in the UK!<br><br>This'll have to do for now but will probaly buy an e13 DRS when I can get hold of one 03 August 2004
