Questions

Ben Dover

Are these just as strong as a bog standard crank bolt?

Posted by Ben Dover on 24/12/2010

Reply from TartyBikes on 26/12/2010

Hi Ben - The SL bolts are fairly strong, and I've used mine on their own to install cranks before. However, if you want to make extra sure that they're not being strained too much, you can use a standard steel M15 crank bolt to tighten your crank on, then replace it with the SL bolt to keep the crank fully tightened. Thanks, Mark

Sam

Are these bolts 12mm threaded? Thanks!

Posted by Sam on 11/02/2011

Reply from TartyBikes on 14/02/2011

Hi Sam - The Echo SL bolts are M15. Thanks, Mark

josh

Will these fit in an Onza T-Pro BB square taper?

Posted by josh on 27/02/2011

Reply from TartyBikes on 28/02/2011

Hi Josh - These only fit M15 ISIS BBs. Sorry!

Mike

Hi will these bolts fit on my Reset Ti BB?

Posted by Mike on 29/04/2011

Reply from TartyBikes on 03/05/2011

Hi Mike - They'll fit perfectly. Thanks, Mark

john

hello : ) i wonder, will these fit an "FSA Platinum Pro ISIS Bottom Bracket, 68 x 113mm" i thought best to ask before i buy. thanks for your help.

Posted by john on 29/06/2011

Reply from TartyBikes on 29/06/2011

Hi John - The Platinum Pro uses an M15 spindle so that should work fine. Thanks, Mark

john

hello : ) Do you know if these will fit a truvativ gigapipe team sl isis ? thanks again : )

Posted by john on 29/06/2011

Reply from TartyBikes on 29/06/2011

Hi John - As long as it's definitely the Team SL BB then these should fit as that particular BB uses an M15 spindle. If it's one of the older Gigapipe BBs then they might not fit as I believe they used to use an M12 spindle. Thanks, Mark

Stefan Cretu

Hey! I'm new to trials so please don't judge :D, is 12.26 the price for a pair?

Posted by Stefan Cretu on 01/09/2012

Reply from TartyBikes on 03/09/2012

Hi Stefan - The price shown is for a pair of bolts. Thanks, Mark

Will Sheppard

Hi I was wondering how long are these bolts from the top to the threads?

Posted by Will Sheppard on 12/12/2012

Reply from TartyBikes on 13/12/2012

Hi Will - These bolts, when you have the spacers fitted, have 16mm of thread. Thanks, Mark

Craig dean

Hi, would these bolts fit a raceface bottom bracket, with a middleburn rs7 crank. Thanks Craig.

Posted by Craig dean on 07/09/2013

Reply from TartyBikes on 09/09/2013

Hi Craig - it depends on the model bottom bracket you have. These will fit some RaceFace BB's, but not others. You can easily find out by taking out your current bolt and measuring the diameter of the threaded section. If they're 15mm these will fit, if they're not then they won't. Thanks, Flipp.

John

May be a silly question. But I've bought these as a non-trials rider for a RaceFace XC crank with ISIS BB. Will the bolts sit well in the crank at the correct diamter - i.e. will they not interfere with the threads on the crank for the crank extractor?

Posted by John on 11/05/2014

Reply from TartyBikes on 12/05/2014

Hi John - thanks for your question. No, that won't be a problem - trials oriented cranks have the same threads in them, so these are designed with them taken into account. Thanks, Flipp.

Louie

Hi there! Will these bolts fit for my older edition (green colour) TryAll isis BB? Thanks

Posted by Louie on 27/08/2014

Reply from TartyBikes on 27/08/2014

Hi Louie - yes, these should fit no problem. Thanks, Flipp.

JP

Hi - I seem to be having a lot of trouble finding a decent set of crankbolts - could I enquire what the diameter is of the upper part, as for stability I really need a 20mm head?

Posted by JP on 06/11/2015

Reply from TartyBikes on 06/11/2015

Hi JP - The outer diameter of the Echo bolts is 20.62mm. Most of our M15 crank bolts are within 0.1mm of this diameter too. If you're having issues with crank wobble then it sounds like it may be the case that the splines have stretched/worn a little rather than the bolts being at fault? If you're having problems with the bolts coming loose then using a dab of threadlock on them may help out. Thanks, Mark

JP

In response - the splines are next to new and it's a fairly indestructable Titanium axle too - the issue I was looking to solve here was poor quality bolts that are all over the market; the ones with poor tool take-up, and incorrect bolt head diameters. The ones ('quality' Ti, ho hum) I tried damaged the alloy top surface of the crank interface, where the bottom of the bolt sits on. You seem to be one of the very few with a; hex key interface bored right through, b; correct diameter top section. And, yes, damage was exacerbated by poor mating surfaces of the BB and axle spline as they are from two different manufacturers; FSA KForce and KCNC. This resulted in a little play and annoying creaks, and that issue will be solved by Loctite 760. Unfortunately I can't escape away from(CR)ISIS as nothing else fits this frame.

Posted by JP on 06/11/2015

Reply from TartyBikes on 06/11/2015

Hi JP - Ah, I see. The SL crank bolts at least have a steel spacer with them so although it'll add a small amount of weight but should stop any marking/damaging to the cranks themselves. As a side note, when installing cranks for the first time, we recommend using a steel crank bolt to get the cranks torqued on there correctly as it'll minimise the chances of the alloy bolt stripping if the cranks are a tight fit on the axle. The Echo bolts are very good though - we use them on our own bikes here and they're much nicer to use than a lot of other bolts thanks to the deep broaching on them. I haven't heard of Locktite 760 before, although we have heard of people using Locktite 270 in similar applications before to good effect. Thanks, Mark

Scott

Hi guys will these bolts fit a Truvativ Howitzer bottom bracket?

Posted by Scott on 07/07/2016

Reply from TartyBikes on 08/07/2016

Hi Scott - Unfortunately these won't fit a Truvativ BB, sorry. You would need M12 bolts for that style of BB. Thanks, Mark

Stewart Hall

Hi. What's the recommended torque setting? Cheers.

Posted by Stewart Hall on 04/02/2018

Reply from TartyBikes on 05/02/2018

Hi Stewart - These bolts need to be torqued up to 35-40Nm, but we do recommend using a steel bolt to initially seat your crank on the splines fully. As always, keeping them nipped up after the first few rides is important! Thanks, Mark

Joe Beale

Would this fit the bottom bracket that comes stock on an onza genesis? Thanks, Joe.

Posted by Joe Beale on 09/07/2013

Reply from TartyBikes on 10/07/2013

Hi Joe - thanks for your question. Unfortunately they wouldn't. The bottom bracket in the Genesis takes M12 bolts, and these are M15. Thanks, Flipp.

These look great.

Posted by Cai on 09/01/2011

These are much lighter than standard steel bolts, but are still easily strong enough to bolt your cranks on nice and tight. They also look great!

Dave

Great item

Posted by Dave on 11/02/2011

These not only save weight but they look good and as they are drilled right through there's no chance of rounding that allen key off!

Jamie

Pimp!

Posted by Jamie on 19/05/2013

Look sweet, allen key fits in there nice and snug, not a chance in the world of it slipping while tightening it up. Cheers!

Reply from TartyBikes on 20/05/2013

Hi Jamie - The extra-deep allen key broaching does make them a little more secure than some other alloy crank bolts out there. It's good to hear you like them! Thanks for the review.
